Tags Share this article 1/18/24 Published For your organization to implement robust security policies, it must have clear information on the security risks it is exposed to. An effective IT security plan must take the organization’s unique set of systems and technologies into account. This helps security professionals decide where to deploy limited resources for improving security processes. Cybersecurity risk assessments provide clear, actionable data about the quality and success of the organization’s current security measures. They offer insight into the potential impact of security threats across the entire organization, giving security leaders the information they need to manage risk more effectively. Conducting a comprehensive cyber risk assessment can help you improve your organization’s security posture, address security-related production bottlenecks in business operations, and make sure security team budgets are wisely spent. This kind of assessment is also a vital step in the compliance process . Organizations must undergo information security risk assessments in order to meet regulatory requirements set by different authorities and frameworks, including: The Health Insurance Portability and Accountability Act (HIPAA), The International Organization for Standardization (ISO) The National Institute of Standards and Technology (NIST) Cybersecurity Framework The Payment Card Industry Data Security Standard (PCI DSS) General Data Protection Regulation (GDPR) What is a Security Risk Assessment? Your organization’s security risk assessment is a formal document that identifies, evaluates, and prioritizes cyber threats according to their potential impact on business operations. Categorizing threats this way allows cybersecurity leaders to manage the risk level associated with them in a proactive, strategic way. The assessment provides valuable data about vulnerabilities in business systems and the likelihood of cyber attacks against those systems. It also provides context into mitigation strategies for identified risks, which helps security leaders make informed decisions during the risk management process. For example, a security risk assessment may find that the organization needs to be more reliant on its firewalls and access control solutions . If a threat actor uses phishing or social engineering to bypass these defenses (or take control of them entirely), the entire organization could suffer a catastrophic data breach. In this case, the assessment may recommend investing in penetration testing and advanced incident response capabilities. Organizations that neglect to invest in network security risk assessments won’t know their weaknesses until after they are actively exploited. By the time hackers launch a ransomware attack, it’s too late to consider whether your antivirus systems are properly configured against malware. Who Should Perform Your Organization’s Cyber Risk Assessment? A dedicated internal team should take ownership over the risk assessment process . The process will require technical personnel with a deep understanding of the organization’s IT infrastructure. Executive stakeholders should also be involved because they understand how information flows in the context of the organization’s business logic, and can provide broad insight into its risk management strategy . Small businesses may not have the resources necessary to conduct a comprehensive risk analysis internally. While a variety of assessment tools and solutions are available on the market, partnering with a reputable managed security service provider is the best way to ensure an accurate outcome. Adhering to a consistent methodology is vital, and experienced vulnerability assessment professionals ensure the best results. How to Conduct a Network Security Risk Assessment 1. Develop a comprehensive asset map The first step is accurately mapping out your organization’s network assets. If you don’t have a clear idea of exactly what systems, tools, and applications the organization uses, you won’t be able to manage the risks associated with them. Keep in mind that human user accounts should be counted as assets as well. The Verizon 2023 Data Breach Investigation Report shows that the human element is involved in more than a quarter of all data breaches. The better you understand your organization’s human users and their privilege profiles, the more effectively you can protect them from potential threats and secure critical assets effectively. Ideally, all of your organization’s users should be assigned and managed through a centralized system. For Windows-based networks, Active Directory is usually the solution that comes to mind. Your organization may have a different system in place if it uses a different operating system. Also, don’t forget about information assets like trade secrets and intellectual property. Cybercriminals may target these assets in order to extort the organization. Your asset map should show you exactly where these critical assets are stored, and provide context into which users have permission to access them. Log and track every single asset in a central database that you can quickly access and easily update. Assign security value to each asset as you go and categorize them by access level . Here’s an example of how you might want to structure that categorization: Public data. This is data you’ve intentionally made available to the public. It includes web page content, marketing brochures, and any other information of no consequence in a data breach scenario. Confidential data. This data is not publicly available. If the organization shares it with third parties, it is only under a non-disclosure agreement. Sensitive technical or financial information may end up in this category. Internal use only. This term refers to data that is not allowed outside the company, even under non-disclosure terms. It might include employee pay structures, long-term strategy documents, or product research data. Intellectual property. Any trade secrets, issued patents, or copyrighted assets are intellectual property. The value of the organization depends in some way on this information remaining confidential. Compliance restricted data. This category includes any data that is protected by regulatory or legal obligations. For a HIPAA-compliant organization, that would include patient data, medical histories, and protected personal information. This database will be one of the most important security assessment tools you use throughout the next seven steps. 2. Identify security threats and vulnerabilities Once you have a comprehensive asset inventory, you can begin identifying risks and vulnerabilities for each asset. There are many different types of tests and risk assessment tools you can use for this step. Automating the process whenever possible is highly recommended, since it may otherwise become a lengthy and time-consuming manual task. Vulnerability scanning tools can automatically assess your network and applications for vulnerabilities associated with known threats. The scan’s results will tell you exactly what kinds of threats your information systems are susceptible to, and provide some information about how you can remediate them. Be aware that these scans can only determine your vulnerability to known threats. They won’t detect insider threats , zero-day vulnerabilities and some scanners may overlook security tool misconfigurations that attackers can take advantage of. You may also wish to conduct a security gap analysis. This will provide you with comprehensive information about how your current security program compares to an established standard like CMMC or PCI DSS. This won’t help protect against zero-day threats, but it can uncover information security management problems and misconfigurations that would otherwise go unnoticed. To take this step to the next level, you can conduct penetration testing against the systems and assets your organization uses. This will validate vulnerability scan and gap analysis data while potentially uncovering unknown vulnerabilities in the process. Pentesting replicates real attacks on your systems, providing deep insight into just how feasible those attacks may be from a threat actor’s perspective. When assessing the different risks your organization faces, try to answer the following questions: What is the most likely business outcome associated with this risk? Will the impact of this risk include permanent damage, like destroyed data? Would your organization be subject to fines for compliance violations associated with this risk? Could your organization face additional legal liabilities if someone exploited this risk? 3. Prioritize risks according to severity and likelihood Once you’ve conducted vulnerability scans and assessed the different risks that could impact your organization, you will be left with a long list of potential threats. This list will include more risks and hazards than you could possibly address all at once. The next step is to go through the list and prioritize each risk according to its potential impact and how likely it is to happen. If you implemented penetration testing in the previous step, you should have precise data on how likely certain attacks are to take place. Your team will tell you how many steps they took to compromise confidential data, which authentication systems they had to bypass, and what other security functionalities they disabled. Every additional step reduces the likelihood of a cybercriminal carrying out the attack successfully. If you do not implement penetration testing, you will have to conduct an audit to assess the likelihood of attackers exploiting your organization’s vulnerabilities. Industry-wide threat intelligence data can give you an idea of how frequent certain types of attacks are. During this step, you’ll have to balance the likelihood of exploitation with the severity of the potential impact for each risk. This will require research into the remediation costs associated with many cyberattacks. Remediation costs should include business impact – such as downtime, legal liabilities, and reputational damage – as well as the cost of paying employees to carry out remediation tasks. Assigning internal IT employees to remediation tasks implies the opportunity cost of diverting them from their usual responsibilities. The more completely you assess these costs, the more accurate your assessment will be. 4. Develop security controls in response to risks Now that you have a comprehensive overview of the risks your organization is exposed to, you can begin developing security controls to address them. These controls should provide visibility and functionality to your security processes, allowing you to prevent attackers from exploiting your information systems and detect them when they make an attempt. There are three main types of security control available to the typical organization: Physical controls prevent unauthorized access to sensitive locations and hardware assets. Security cameras, door locks, and live guards all contribute to physical security. These controls prevent external attacks from taking place on premises. Administrative controls are policies, practices, and workflows that secure business assets and provide visibility into workplace processes. These are vital for protecting against credential-based attacks and malicious insiders. Technical controls include purpose-built security tools like hardware firewalls, encrypted data storage solutions, and antivirus software. Depending on their configuration, these controls can address almost any type of threat. These categories have further sub-categories that describe how the control interacts with the threat it is protecting against. Most controls protect against more than one type of risk, and many controls will protect against different risks in different ways. Here are some of the functions of different controls that you should keep in mind: Detection-based controls trigger alerts when they discover unauthorized activity happening on the network. Intrusion detection systems (IDS) and security information and event management (SIEM) platforms are examples of detection-based solutions. When you configure one of these systems to detect a known risk, you are implementing a detection-based technical control. Prevention-based controls block unauthorized activity from taking place altogether. Authentication protocols and firewall rules are common examples of prevention-based security controls. When you update your organization’s password policy, you are implementing a prevention-based administrative control. Correction and compensation-based controls focus on remediating the effects of cyberattacks once they occur. Disaster recovery systems and business continuity solutions are examples. When you copy a backup database to an on-premises server, you are establishing physical compensation-based controls that will help you recover from potential threats. 5. Document the results and create a remediation plan Once you’ve assessed your organization’s exposure to different risks and developed security controls to address those risks, you are ready to condense them into a cohesive remediation plan . You will use the data you’ve gathered so far to justify the recommendations you make, so it’s a good idea to present that data visually. Consider creating a risk matrix to show how individual risks compare to one another based on their severity and likelihood. High-impact risks that have a high likelihood of occurring should draw more time and attention than risks that are either low-impact, unlikely, or both. Your remediation plan will document the steps that security teams will need to take when responding to each incident you describe. If multiple options exist for a particular vulnerability, you may add a cost/benefit analysis of multiple approaches. This should provide you with an accurate way to quantify the cost of certain cyberattacks and provide a comparative cost for implementing controls against that type of attack. Comparing the cost of remediation with the cost of implementing controls should show some obvious options for cybersecurity investment. It’s easy to make the case for securing against high-severity, high-likelihood attacks with high remediation costs and low control costs. Implementing security patches is an example of this kind of security control that costs very little but provides a great deal of value in this context. Depending on your organization’s security risk profile, you may uncover other opportunities to improve security quickly. You will probably also find opportunities that are more difficult or expensive to carry out. You will have to pitch these opportunities to stakeholders and make the case for their approval. 6. Implement recommendations and evaluate the effectiveness of your assessment Once you have approval to implement your recommendations, it’s time for action. Your security team can now assign each item in the remediation plan to the team member responsible and oversee their completion. Be sure to allow a realistic time frame for each step in the process to be completed – especially if your team is not actively executing every task on its own. You should also include steps for monitoring the effectiveness of their efforts and documenting the changes they make to your security posture. This will provide you with key performance metrics that you can compare with future network security assessments moving forward, and help you demonstrate the value of your remediation efforts overall. Once you have implemented the recommendations, you can monitor and optimize the performance of your information systems to ensure your security posture adapts to new threats as they emerge. Risk assessments are not static processes, and you should be prepared to conduct internal audits and simulate the impact of configuration changes on your current deployment. You may wish to repeat your risk evaluation and gap analysis step to find out how much your organization’s security posture has changed. You can use automated tools like AlgoSec to conduct configuration simulations and optimize the way your network responds to new and emerging threats. Investing time and energy into these tasks now will lessen the burden of your next network security risk assessment and make it easier for you to gain approval for the recommendations you make in the future.

Tags Share this article 2/12/24 Published Network vulnerability scanning provides in-depth insight into your organization’s security posture and highlights the specific types of vulnerabilities attackers may exploit when targeting it. These tools work by systematically scanning your network environment — including all desktops, laptops, mobile endpoints, servers, and other assets for known weaknesses and misconfigurations. Your analyzer then produces a detailed report that tells you exactly how hackers might breach your systems. Find out how these important tools contribute to successfully managing your security policies and protecting sensitive assets from cybercriminals and malware. What is Network Vulnerability Management? Network vulnerability scanners are cybersecurity solutions typically delivered under a software-as-a-service (SaaS) model. These solutions match your network asset configurations with a comprehensive list of known misconfigurations and security threats, including unpatched software, open ports, and other security issues. By comparing system details against a comprehensive database of known vulnerabilities, network scanning helps pinpoint areas of weakness that could potentially be exploited by threat actors. This proactive approach is essential for maintaining robust network security and protecting sensitive data from unauthorized access and cyberattacks. This provides your organization with several valuable benefits: Early detection of known security vulnerabilities. If your organization is exposed to security threats that leverage known vulnerabilities, you’ll want to address these security gaps as soon as possible. Comprehensive data for efficient risk management. Knowing exactly how many security vulnerabilities your organization is exposed to gives you clear data for conducting in-depth risk management . Regulatory compliance. Many regulatory compliance frameworks like SOC 2, ISO 27001, and PCI DSS require organizations to undergo regular vulnerability scanning. Reduced costs. Automating the process of scanning for vulnerabilities reduces the costs associated with discovering and remediating security weaknesses manually. Key Features and Functions The best network security vulnerability scanners have several important features in common: Prioritized vulnerability assessment tools. You need to be able to assess and prioritize vulnerabilities based on their severity. This allows you to commit security resources to addressing high-priority vulnerabilities first, and taking care of low-impact weaknesses afterwards. Automation and real-time analysis. Manual scanning is a difficult and time-consuming process. Your vulnerability scanner must support automated, ongoing scanning for real-time vulnerability detection, providing on-demand insights into your security risk profile. Integration with remediation tools: The best network vulnerability scanners integrate with other security tools for quick mitigation and remediation. This lets security teams quickly close security gaps and move on to the next, without having to spend time accessing and managing a separate set of security tools. How Network Vulnerability Scanning Tools Work Step 1. Scanning Process Initial network mapping is the first step in the vulnerability scanning process. At this point, your scanner maps your entire network and identifies every device and asset connected to it. This includes all web servers, workstations, firewalls , and network devices. The automatic discovery process should produce a comprehensive map showing how your network is connected, and show detailed information about each network device. It should include comprehensive port scanning to identify open ports that attackers could use to gain entry to the network. Step 2. Detection Techniques The next step in the process involves leveraging advanced detection techniques to identify known vulnerabilities in the network. Most network vulnerability scanners rely on two specific techniques to achieve this: Signature-Based Detection: The scanner checks for known vulnerabilities by comparing system details against a database of known issues. This database is drawn from extensive threat intelligence feeds and public records like the MITRE CVE Program . Heuristic Analysis: This technique relies on heuristic and behavioral techniques to identify unknown or zero-day vulnerabilities based on unusual system behavior or configurations. It may detect suspicious activities that don’t correspond to known threats, prompting further investigation. Step 3. Vulnerability Identification This step involves checking network assets for known vulnerabilities according to their unique risk profile. This includes scanning for outdated software and operating system versions, and looking for misconfigurations in network devices and settings. Most network scanners achieve this by pinging network-accessible systems, sending them TCP/UDP packets, and remotely logging into compatible systems to gather detailed information about them. Highly advanced network vulnerability scanning tools have more comprehensive sets of features for identifying these vulnerabilities, because they recognize a wider, more up-to-date range of network devices. Step 4. Assessment and Reporting This step describes the process of matching network data to known vulnerabilities and prioritizing them based on their severity. Advanced network scanning devices may use automation and sophisticated scripting to produce a list of vulnerabilities and exposed network components. First, each vulnerability is assessed for its potential impact and risk level, often based on industry-wide compliance standards like NIST. Then the tool prioritizes each vulnerability based on its severity, ease of exploitation, and potential impact on the network. Afterwards, the tool generates a detailed report outlining every vulnerability assessed and ranking it according to its severity. These reports guide the security teams in addressing the identified issues. Step 5. Continuous Monitoring and Updates Scanning for vulnerabilities once is helpful, but it won’t help you achieve the long-term goal of keeping your network protected against new and emerging threats. To do that, you need to continuously monitor your network for new weaknesses and establish workflows for resolving security issues proactively. Many advanced scanners provide real-time monitoring, constantly scanning the network for new vulnerabilities as they emerge. Regular updates to the scanner’s vulnerability database ensure it can recognize the latest known vulnerabilities and threats. If your vulnerability scanner doesn’t support these two important features, you may need to invest additional time and effort into time-consuming manual operations that achieve the same results. Step 6. Integration with Other Security Measures Security leaders must pay close attention to what happens after a vulnerability scan detects an outdated software patch or misconfiguration. Alerting security teams to the danger represented by these weaknesses is only the first step towards actually resolving them, and many scanning tools offer comprehensive integrations for launching remediation actions. Remediation integrations are valuable because they allow security teams to quickly address vulnerabilities immediately upon discovering them. The alternative is creating a list of weaknesses and having the team manually go through them, which takes time and distracts from higher-impact security tasks. Another useful integration involves large-scale security posture analytics. If your vulnerability assessment includes analysis and management tools for addressing observable patterns in your network vulnerability scans, it will be much easier to dedicate resources to the appropriate security-enhancing initiatives. Choosing a Network Vulnerability Scanning Solution There are two major categories of features that network vulnerability scanning tools must offer in order to provide best-in-class coverage against sophisticated threats. Keep these aspects in mind when reviewing your options for deploying vulnerability scans in your security workflow. Important Considerations Comprehensive Vulnerability Database. Access to an extensive CVE database is vital. Many of these are open-source and available to the general public, but the sheer number of CVE records can drag down performance. The best vulnerability management tools have highly optimized APIs capable of processing these records quickly. Customizability and Templates. Tailoring scans to specific needs and environments is important for every organization, but it takes on special significance for organizations seeking to demonstrate regulatory compliance. That’s because the outcome of compliance assessments and audits will depend on the quality of data included in your reports. False Positive Management. All vulnerability scanners are susceptible to displaying false positives, but some manage these events better than others. This is especially important in misconfiguration cases, because it can cause security teams to mistakenly misconfigure security tools that were configured correctly in the first place. Business Essentials Support for Various Platforms. Your vulnerability scan must ingest data from multiple operating systems like Windows, Linux, and a variety of cloud platforms. If any of these systems are not compatible with the scanning process, you may end up with unstable performance or unreliable data. Reporting and Analytics. Detailed reports and analytics help you establish a clear security posture assessment. Your vulnerability management tool must provide clear reports that are easy for non-technical stakeholders to understand. This will help you make the case for necessary security investments in the future. Scalability and Flexibility. These solutions must scale with the growth of your organization’s IT infrastructure . Pay attention to the usage and payment model each vulnerability scanning vendor uses. Some of them may be better suited to small, growing organizations while others are more appropriate for large enterprises and government agencies. Top 5 Network Vulnerability Scanning Providers 1.

Risk Management and Vulnerabilities Removing insecure protocols In networks Matthew Pascucci 2 min read Matthew Pascucci Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 7/15/14 Published Insecure Service Protocols and Ports Okay, we all have them… they’re everyone’s dirty little network security secrets that we try not to talk about. They’re the protocols that we don’t mention in a security audit or to other people in the industry for fear that we’ll be publicly embarrassed. Yes, I’m talking about cleartext protocols which are running rampant across many networks. They’re in place because they work, and they work well, so no one has had a reason to upgrade them. Why upgrade something if it’s working right? Wrong. These protocols need to go the way of records, 8-tracks and cassettes (many of these protocols were fittingly developed during the same era). You’re putting your business and data at serious risk by running these insecure protocols. There are many insecure protocols that are exposing your data in cleartext, but let’s focus on the three most widely used ones: FTP, Telnet and SNMP. FTP (File Transfer Protocol) This is by far the most popular of the insecure protocols in use today. It’s the king of all cleartext protocols and one that needs to be smitten from your network before it’s too late. The problem with FTP is that all authentication is done in cleartext which leaves little room for the security of your data. To put things into perspective, FTP was first released in 1971, almost 45 years ago. In 1971 the price of gas was 40 cents a gallon, Disneyland had just opened and a company called FedEx was established. People, this was a long time ago. You need to migrate from FTP and start using an updated and more secure method for file transfers, such as HTTPS, SFTP or FTPS. These three protocols use encryption on the wire and during authentication to secure the transfer of files and login. Telnet If FTP is the king of all insecure file transfer protocols then telnet is supreme ruler of all cleartext network terminal protocols. Just like FTP, telnet was one of the first protocols that allowed you to remotely administer equipment. It became the defacto standard until it was discovered that it passes authentication using cleartext. At this point you need to hunt down all equipment that is still running telnet and replace it with SSH, which uses encryption to protect authentication and data transfer. This shouldn’t be a huge change unless your gear cannot support SSH. Many appliances or networking gear running telnet will either need the service enabled or the OS upgraded. If both of these options are not appropriate, you need to get new equipment, case closed. I know money is an issue at times, but if you’re running a 45 year old protocol on your network with the inability to update it, you need to rethink your priorities. The last thing you want is an attacker gaining control of your network via telnet. Its game over at this point. SNMP (Simple Network Management Protocol) This is one of those sneaky protocols that you don’t think is going to rear its ugly head and bite you, but it can! escortdate escorts . There are multiple versions of SNMP, and you need to be particularly careful with versions 1 and 2. For those not familiar with SNMP, it’s a protocol that enables the management and monitoring of remote systems. Once again, the strings can be sent via cleartext, and if you have access to these credentials you can connect to the system and start gaining a foothold on the network, including managing, applying new configurations or gaining in-depth monitoring details of the network. In short, it a great help for attackers if they can get hold of these credentials. Luckily version 3.0 of SNMP has enhanced security that protects you from these types of attacks. So you must review your network and make sure that SNMP v1 and v2 are not being used. These are just three of the more popular but insecure protocols that are still in heavy use across many networks today. By performing an audit of your firewalls and systems to identify these protocols, preferably using an automated tool such as AlgoSec Firewall Analyzer , you should be able to pretty quickly create a list of these protocols in use across your network. It’s also important to proactively analyze every change to your firewall policy (again preferably with an automated tool for security change management ) to make sure no one introduces insecure protocol access without proper visibility and approval. Finally, don’t feel bad telling a vendor or client that you won’t send data using these protocols. If they’re making you use them, there’s a good chance that there are other security issues going on in their network that you should be concerned about. It’s time to get rid of these protocols. They’ve had their usefulness, but the time has come for them to be sunset for good. Schedule a demo Related Articles Q1 at AlgoSec: What innovations and milestones defined our start to 2026?

Tags Share this article 8/15/20 Published As you may have heard already, the National Security Agency (NSA) and the Federal Bureau of Investigation (FBI) released a joint Cybersecurity Advisory about previously undisclosed Russian malware called Drovorub. According to the report, the malware is designed for Linux systems as part of its cyber espionage operations. Drovorub is a Linux malware toolset that consists of an implant coupled with a kernel module rootkit, a file transfer and port forwarding tool, and a Command and Control (C2) server. The name Drovorub originates from the Russian language. It is a complex word that consists of 2 roots (not the full words): “drov” and “rub” . The “o” in between is used to join both roots together. The root “drov” forms a noun “drova” , which translates to “firewood” , or “wood” . The root “rub” /ˈruːb/ forms a verb “rubit” , which translates to “to fell” , or “to chop” . Hence, the original meaning of this word is indeed a “woodcutter” . What the report omits, however, is that apart from the classic interpretation, there is also slang. In the Russian computer slang, the word “drova” is widely used to denote “drivers” . The word “rubit” also has other meanings in Russian. It may mean to kill, to disable, to switch off. In the Russian slang, “rubit” also means to understand something very well, to be professional in a specific field. It resonates with the English word “sharp” – to be able to cut through the problem. Hence, we have 3 possible interpretations of ‘ Drovorub ‘: someone who chops wood – “дроворуб” someone who disables other kernel-mode drivers – “тот, кто отрубает / рубит драйвера” someone who understands kernel-mode drivers very well – “тот, кто (хорошо) рубит в драйверах” Given that Drovorub does not disable other drivers, the last interpretation could be the intended one. In that case, “Drovorub” could be a code name of the project or even someone’s nickname. Let’s put aside the intricacies of the Russian translations and get a closer look into the report. DISCLAIMER Before we dive into some of the Drovorub analysis aspects, we need to make clear that neither FBI nor NSA has shared any hashes or any samples of Drovorub. Without the samples, it’s impossible to conduct a full reverse engineering analysis of the malware. Netfilter Hiding According to the report, the Drovorub-kernel module registers a Netfilter hook. A network packet filter with a Netfilter hook ( NF_INET_LOCAL_IN and NF_INET_LOCAL_OUT ) is a common malware technique. It allows a backdoor to watch passively for certain magic packets or series of packets, to extract C2 traffic. What is interesting though, is that the driver also hooks the kernel’s nf_register_hook() function. The hook handler will register the original Netfilter hook, then un-register it, then re-register the kernel’s own Netfilter hook. According to the nf_register_hook() function in the Netfilter’s source , if two hooks have the same protocol family (e.g., PF_INET ), and the same hook identifier (e.g., NF_IP_INPUT ), the hook execution sequence is determined by priority. The hook list enumerator breaks at the position of an existing hook with a priority number elem->priority higher than the new hook’s priority number reg->priority : int nf_register_hook ( struct nf_hook_ops * reg) { struct nf_hook_ops * elem; int err; err = mutex_lock_interruptible( & nf_hook_mutex); if (err < 0 ) return err; list_for_each_entry(elem, & nf_hooks[reg -> pf][reg -> hooknum], list) { if (reg -> priority < elem -> priority) break ; } list_add_rcu( & reg -> list, elem -> list.prev); mutex_unlock( & nf_hook_mutex); ... return 0 ; } In that case, the new hook is inserted into the list, so that the higher-priority hook’s PREVIOUS link would point into the newly inserted hook. What happens if the new hook’s priority is also the same, such as NF_IP_PRI_FIRST – the maximum hook priority? In that case, the break condition will not be met, the list iterator list_for_each_entry will slide past the existing hook, and the new hook will be inserted after it as if the new hook’s priority was higher. By re-inserting its Netfilter hook in the hook handler of the nf_register_hook() function, the driver makes sure the Drovorub’s Netfilter hook will beat any other registered hook at the same hook number and with the same (maximum) priority. If the intercepted TCP packet does not belong to the hidden TCP connection, or if it’s destined to or originates from another process, hidden by Drovorub’s kernel-mode driver, the hook will return 5 ( NF_STOP ). Doing so will prevent other hooks from being called to process the same packet. Security Implications For Docker Containers Given that Drovorub toolset targets Linux and contains a port forwarding tool to route network traffic to other hosts on the compromised network, it would not be entirely unreasonable to assume that this toolset was detected in a client’s cloud infrastructure. According to Gartner’s prediction , in just two years, more than 75% of global organizations will be running cloud-native containerized applications in production, up from less than 30% today. Would the Drovorub toolset survive, if the client’s cloud infrastructure was running containerized applications? Would that facilitate the attack or would it disrupt it? Would it make the breach stealthier? To answer these questions, we have tested a different malicious toolset, CloudSnooper, reported earlier this year by Sophos. Just like Drovorub, CloudSnooper’s kernel-mode driver also relies on a Netfilter hook ( NF_INET_LOCAL_IN and NF_INET_LOCAL_OUT ) to extract C2 traffic from the intercepted TCP packets. As seen in the FBI/NSA report, the Volatility framework was used to carve the Drovorub kernel module out of the host, running CentOS. In our little lab experiment, let’s also use CentOS host. To build a new Docker container image, let’s construct the following Dockerfile: FROM scratch ADD centos-7.4.1708-docker.tar.xz / ADD rootkit.ko / CMD [“/bin/bash”] The new image, built from scratch, will have the CentOS 7.4 installed. The kernel-mode rootkit will be added to its root directory. Let’s build an image from our Dockerfile, and call it ‘test’: [root@localhost 1]# docker build . -t test Sending build context to Docker daemon 43.6MB Step 1/4 : FROM scratch —> Step 2/4 : ADD centos-7.4.1708-docker.tar.xz / —> 0c3c322f2e28 Step 3/4 : ADD rootkit.ko / —> 5aaa26212769 Step 4/4 : CMD [“/bin/bash”] —> Running in 8e34940342a2 Removing intermediate container 8e34940342a2 —> 575e3875cdab Successfully built 575e3875cdab Successfully tagged test:latest Next, let’s execute our image interactively (with pseudo-TTY and STDIN ): docker run -it test The executed image will be waiting for our commands: [root@8921e4c7d45e /]# Next, let’s try to load the malicious kernel module: [root@8921e4c7d45e /]# insmod rootkit.ko The output of this command is: insmod: ERROR: could not insert module rootkit.ko: Operation not permitted The reason why it failed is that by default, Docker containers are ‘unprivileged’. Loading a kernel module from a docker container requires a special privilege that allows it doing so. Let’s repeat our experiment. This time, let’s execute our image either in a fully privileged mode or by enabling only one capability – a capability to load and unload kernel modules ( SYS_MODULE ). docker run -it –privileged test or docker run -it –cap-add SYS_MODULE test Let’s load our driver again: [root@547451b8bf87 /]# insmod rootkit.ko This time, the command is executed silently. Running lsmod command allows us to enlist the driver and to prove it was loaded just fine. A little magic here is to quit the docker container and then delete its image: docker rmi -f test Next, let’s execute lsmod again, only this time on the host. The output produced by lsmod will confirm the rootkit module is loaded on the host even after the container image is fully unloaded from memory and deleted! Let’s see what ports are open on the host: [root@localhost 1]# netstat -tulpn Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1044/sshd With the SSH server running on port 22 , let’s send a C2 ‘ping’ command to the rootkit over port 22 : [root@localhost 1]# python client.py 127.0.0.1 22 8080 rrootkit-negotiation: hello The ‘hello’ response from the rootkit proves it’s fully operational. The Netfilter hook detects a command concealed in a TCP packet transferred over port 22 , even though the host runs SSH server on port 22 . How was it possible that a rootkit loaded from a docker container ended up loaded on the host? The answer is simple: a docker container is not a virtual machine. Despite the namespace and ‘control groups’ isolation, it still relies on the same kernel as the host. Therefore, a kernel-mode rootkit loaded from inside a Docker container instantly compromises the host, thus allowing the attackers to compromise other containers that reside on the same host. It is true that by default, a Docker container is ‘unprivileged’ and hence, may not load kernel-mode drivers. However, if a host is compromised, or if a trojanized container image detects the presence of the SYS_MODULE capability (as required by many legitimate Docker containers), loading a kernel-mode rootkit on a host from inside a container becomes a trivial task. Detecting the SYS_MODULE capability ( cap_sys_module ) from inside the container: [root@80402f9c2e4c /]# capsh –print Current: = cap_chown, … cap_sys_module, … Conclusion This post is drawing a parallel between the recently reported Drovorub rootkit and CloudSnooper, a rootkit reported earlier this year. Allegedly built by different teams, both of these Linux rootkits have one mechanism in common: a Netfilter hook ( NF_INET_LOCAL_IN and NF_INET_LOCAL_OUT ) and a toolset that enables tunneling of the traffic to other hosts within the same compromised cloud infrastructure. We are still hunting for the hashes and samples of Drovorub. Unfortunately, the YARA rules published by FBI/NSA cause False Positives. For example, the “Rule to detect Drovorub-server, Drovorub-agent, and Drovorub-client binaries based on unique strings and strings indicating statically linked libraries” enlists the following strings: “Poco” “Json” “OpenSSL” “clientid” “—–BEGIN” “—–END” “tunnel” The string “Poco” comes from the POCO C++ Libraries that are used for over 15 years. It is w-a-a-a-a-y too generic, even in combination with other generic strings. As a result, all these strings, along with the ELF header and a file size between 1MB and 10MB, produce a false hit on legitimate ARM libraries, such as a library used for GPS navigation on Android devices: f058ebb581f22882290b27725df94bb302b89504 56c36bfd4bbb1e3084e8e87657f02dbc4ba87755 Nevertheless, based on the information available today, our interest is naturally drawn to the security implications of these Linux rootkits for the Docker containers. Regardless of what security mechanisms may have been compromised, Docker containers contribute an additional attack surface, another opportunity for the attackers to compromise the hosts and other containers within the same organization. The scenario outlined in this post is purely hypothetical. There is no evidence that supports that Drovorub may have affected any containers. However, an increase in volume and sophistication of attacks against Linux-based cloud-native production environments, coupled with the increased proliferation of containers, suggests that such a scenario may, in fact, be plausible.

At a time when many organizations are moving their resources to the cloud and security threats are at an all-time high, focusing on your cloud security architecture has never been more critical. While cloud adoption has revolutionized businesses, it has also brought complex challenges. For example, cloud environments can be susceptible to numerous security threats. Besides, there are compliance regulations that you must address. This is why it’s essential to implement the right methods, frameworks, and best practices in cloud environments. Doing so can protect your organization’s sensitive cloud resources, help you meet compliance regulations, and maintain customer trust. Understanding Cloud Security Architecture Cloud security architecture is the umbrella term that covers all the hardware, software, and technologies used to protect your cloud environment. It encompasses the configurations and secure activities that protect your data, workloads, applications, and infrastructure within the cloud. This includes identity and access management (IAM), application and data protection, compliance monitoring, secure DevOps, governance, and physical infrastructure security. A well-defined security architecture also enables manageable decompositions of cloud deployments, including mixed SaaS, PaaS, and IaaS deployments. This helps you highlight specific security needs in each cloud area. Additionally, it facilitates integration between clouds, zones, and interfaces, ensuring comprehensive coverage of all deployment aspects. Cloud security architects generally use a layered approach when designing cloud security. Not only does this improve security, but it also allows companies to align business needs with technical security practices. As such, a different set of cloud stakeholders, including business teams and technical staff, can derive more value. The Fundamentals of Cloud Security Architecture Every cloud computing architecture has three core fundamental capabilities; confidentiality, integrity, and availability. This is known as the CIA triad. Understanding each capability will guide your efforts to build, design, and implement safer cloud environments. 1. Confidentiality This is the ability to keep information hidden and inaccessible to unauthorized entities, such as attackers, malware, and people in your organization, without the appropriate access level. Privacy and trust are also part of confidentiality. When your organization promises customers to handle their data with utmost secrecy, you’re assuring them of confidentiality. 2. Integrity Integrity means that the services, systems, and applications work and behave exactly how you expect. That is, their output is consistent, accurate, and trustworthy. If these systems and applications are compromised and produce unexpected or misleading results, your organization may suffer irreparable damage. 3. Availability As the name implies, availability assures your cloud resources are consistently accessible and operational when needed. So, suppose an authorized user (whether customers or employees) needs data and applications in the cloud, such as your products or services. In that case, they can access it without interruption or significant downtime. Cybercriminals sometimes use denial-of-service (DoS) attacks to prevent the availability of cloud resources. When this happens, your systems become unavailable to you or your customers, which isn’t ideal. So, how do you stop that from happening and ensure your cloud security architecture provides these core capabilities? Approaches to Cloud Security Architecture There are multiple security architecture approaches, including frameworks and methodologies, to support design and implementation steps. Cloud Security Frameworks and Methodologies A cloud security framework outlines a set of guidelines and controls your organizations can use when securing data, applications, and infrastructures within the cloud computing environment. Frameworks provide a structured approach to detecting risks and implementing appropriate security protocols to prevent them. Without a consistent cloud security framework, your organization exposes itself to more vulnerabilities. You may lack the comprehensive visibility to ensure your data and applications are adequately secure from unauthorized access, data exposure, malware, and other security threats. Plus, you may have limited incident response capabilities, inconsistent security practices, and increased operational risks. A cloud security framework also helps you stay compliant with regulatory requirements. Lastly, failing to have appropriate security frameworks can erode customer trust and confidence in your ability to protect their privacy. This is why you must implement a recognized framework to significantly reduce potential risks associated with cloud security and ensure the CIA of data and systems. There are numerous security frameworks. Some are for governance (e.g., COBIT and COSO), architecture (e.g., SABSA), and the NIST cybersecurity framework. While these generally apply broadly to technology, they may also apply to cloud environments. Other cloud-specific frameworks include the ISO/IEC 27017:2015, Cloud Control Matrix (CCM), Cloud Security Alliance, and the FedRAMP. 1. NIST Cybersecurity Framework (NIST CSF) The National Institute of Standards and Technology’s Cybersecurity Framework (NIST CSF) outlines a set of guidelines for securing security systems. It has five core capabilities: Identify, Protect, Detect, Respond, and Recover. Identify – What processes, assets, and systems need protection? Protect – Develop and implement the right safeguards to ensure critical infrastructure services delivery. Detect – Implement the appropriate mechanisms to enable the timely discovery of cybersecurity incidents. Respond – Develop techniques to contain the impact of potential cybersecurity incidents. Recover – Implement appropriate measures to restore business capabilities and services affected by cybersecurity events. While the NIST CSF is a general framework for the security of your organization’s systems, these five pillars can help you assess and manage cloud-related security risks. 2. ISO/IEC 27017:2015 ISO 27017 is a cloud security framework that defines guidelines on information security issues specific to the cloud. The framework’s security controls add to the ISO/IEC 27002 and ISO/IEC 27001 standards’ recommendations. The framework also offers specific security measures and implementation advice for cloud service providers and applications. 3. Sherwood Applied Business Security Architecture (SABSA) First developed by John Sherwood, SABSA is an Enterprise Security Architecture Framework that provides guidelines for developing business-driven, risk, and opportunity-focused security architectures to support business objectives. The SABSA framework aims to prioritize your business needs, meaning security services are designed and developed to be an integral part of your business and IT infrastructure. Here are some core principles of the Gartner-recommended SABSA framework for enterprises: It is business-driven. SABSA ensures security is integrated into your entire business strategy. This means there’s a strong emphasis on understanding your organization’s business objectives. So, any security measure is aligned with those objectives. SABSA is a risk-based approach. It considers security vulnerabilities, threats, and their potential impacts to prioritize security operations and investments. This helps your organization allocate resources effectively to address the most critical risks first. It promotes a layered security architecture. Earlier, we mentioned how a layered approach can help you align business and technical needs. So, it’s expected that this is a core principle of SABSA. This allows you to deploy multiple security controls across different layers, such as physical security, network security, application security, and data security. Each layer focuses on a specific security aspect and provides special controls and measures. Transparency: SABSA provides two-way traceability; that is, a clear two-way relationship exists between aligning security requirements and business goals. This provides a clear overview of where expenditure is made ad the value that is returned. Modular approach: SABSA offers agility for ease of implementation and management. This can make your business flexible when meeting changing market or economic conditions. 4. MITRE ATT&CK The MITRE ATT&CK framework is a repository of techniques and tactics that threat hunters, defenders, red teams, and security architects can use to classify, identify, and assess attacks. Instead of focusing on security controls and mechanisms to mitigate threats, this framework targets the techniques that hackers and other threat actors use in the cloud. So, using this framework can be excellent if you want to understand how potential attack vectors operate. It can help you become proactive and strengthen your cloud security posture through improved detection and incident response. 5. Cloud Security Alliance Cloud Controls Matrix (CSA CCM) The CSA CCM is a cybersecurity control framework specifically for cloud computing. It contains 197 control objectives structured in 17 domains that cover every critical aspect of cloud technology. Cloud customers and cloud service providers (CSPs) can use this tool to assess cloud implementation systematically. It also guides customers on the appropriate security controls for implementation by which actor in the cloud supply chain. 6. Cloud Security Alliance Security Trust Assurance and Risk (CSA STAR) The CSA STAR framework is for CSPs. It combines the principles of transparency, thorough auditing, and harmonization of standards. What CSA STAR does is to help you, as a cloud customer, assess a cloud service provider’s reliability and security posture. There are two ways this can happen: CSA STAR Certification: This is a rigorous third-party assessment of the CSP’s security controls, posture, and practices. The CSP undergoes a thorough audit based on the CSA’s Cloud Control Matrix (CCM), which is a set of cloud security controls aligned with industry standards. CSA STAR Self-Assessment: The CSA also has a Consensus Assessment Initiative Questionnaire (CAIQ). CSPs can use this to test and report on their security controls and practices. Since it’s a self-assessment procedure, it allows CSPs to be transparent, enabling customers like you to understand a CSP’s security capabilities before adopting their services. Challenges and Considerations in Cloud Security Architecture Before any cloud deployment, it’s important to understand the threats you may face, such as privilege-based attacks and malware, and be prepared for them. Since there are many common threats, we’ll quickly run through the most high-profile ones with the most devastating impacts. It’s important to remember some threats may also be specific to the type of cloud service model. 1. Insider risks This includes the employees in your organization who have access to data, applications, and systems, as well as CSP administrators. Whenever you subscribe to a CSP’s services, you entrust your workloads to the staff who maintain the CSP architecture. 2. DoS attacks Direct denial-of-service (DDoS) attacks are critical issues in cloud environments. Although security perimeters can deflect temporary DDoS attacks to filter out repeated requests, permanent DoS attacks are more damaging to your firmware and render the server unbootable. If this happens, you may need to physically reload the firmware and rebuild the system from the ground up, resulting in business downtime for weeks or longer. 3. Data availability You also want to consider how much of your data is accessible to the government. Security professionals are focusing on laws and examples that demonstrate when and how government authorities can access data in the cloud, whether through legal processes or court rulings. 4. Cloud-connected Edge Systems The concept of “cloud edge” encompasses both edge systems directly connected to the cloud and server architecture that is not directly controlled by the cloud service provider (CSP). To extend their services to smaller or remote locations, global CSPs often rely on partners as they cannot have facilities worldwide. Consequently, CSPs may face limitations in fully regulating hardware monitoring, ensuring physical box integrity, and implementing attack defenses like blocking USB port access. 5. Hardware Limitations Having the most comprehensive cloud security architecture still won’t help you create stronger passwords. While your cloud security architects focus on the firmware, hardware, and software, it’s down to the everyday users to follow best practices for staying safe. Best Practices in Cloud Security Architecture The best practices in Cloud Security Architecture are highlighted below: 1. Understand the shared responsibility model Cloud security is implemented with a shared responsibility model. Although, as the cloud customer, you may have most of the obligation, the cloud provider also shares some of the responsibility. Most vendors, such as Amazon Web Services (AWS) and Microsoft Azure, have documentation that clearly outlines your specific responsibilities depending on the deployment type. It’s important to clearly understand your shared responsibility model and review cloud vendor policies. This will prevent miscommunications and security incidents due to oversight. 2. Secure network design and segmentation This is one of the principles of cloud security architecture – and by extension, a best practice. Secure network design and segmentation involve dividing the network into isolated segments to avoid lateral movements during a breach. Implementing network segmentation allows your organization to contain potential risks and attacks within a specific segment. This can minimize the effects of an incident on your entire network and protect critical assets within the cloud infrastructure. 3. Deploy an Identity and access management (IAM) solution Unauthorized access is one of the biggest problems facing cloud security. Although hackers now use sophisticated tools to gain access to sensitive data, implementing a robust identity and access management (IAM) system can help prevent many threats. Consider access policies like role-based access control (RBAC) permissions, multi-factor authentication (MFA), and continuous threat monitoring. 4. Consider a CASB or Cloud Security Solution (e.g., Cloud-Native Application Protection (CNAPP) and Cloud Workload Protection Platforms (CWPP) Cloud Access Security Brokers (CASBs) provide specialized tools to enforce cloud security policies. Implementing a CASB solution is particularly recommended if you have a multi-cloud environment involving different vendors. Since a CASB acts as an intermediary between your organization’s on-premise infrastructure and CSPs, it allows your business to extend security policies and controls to the cloud. CASBs can enhance your data protection through features like data loss prevention, tokenization, and encryption. Plus, they help you discover and manage shadow IT through visibility into unauthorized cloud services and applications. Besides CASB solutions, you should also consider other solutions for securing your cloud environments. This includes cloud-native application protection (CNAPP) and cloud workload protection platforms (CWPP). For example, a CNAPP like Horizon ACE can improve your cloud security architecture with tailored solutions and automated security management. 5. Conduct Audits, Penetration Testing, and Vulnerability Testing Whether or not you outsource security, performing regular penetration tests and vulnerability is necessary. This helps you assess the effectiveness of your cloud security measures and identify potential weaknesses before hackers exploit them. You should also perform security audits that evaluate cloud security vendors’ capabilities and ensure appropriate access controls are in place. This can be achieved by using the guidelines of some frameworks we mentioned earlier, such as the CSA STAR. 6. Train Your Staff Rather than hiring new hires, training your current staff may be beneficial. Your employees have been at your company for a while and are already familiar with the organization’s culture, values, and processes. This could give them an advantage over new hires. As most existing IT skills can be reused, upskilling employees is more efficient and may help you meet the immediate need for a cloud IT workforce. Train your staff on recognizing simple and complex cybersecurity threats, such as creating strong passwords, identifying social engineering attacks, and advanced topics like risk management. 7. Mitigate Cloud Misconfigurations A misconfigured bucket could give access to anyone on the internet. To minimize cloud misconfigurations and reduce security risks, managing permissions in cloud services carefully is crucial. Misconfigurations, such as granting excessive access permissions to external users, can enable unauthorized access and potential data breaches. Attackers who compromise credentials can escalate their privileges, leading to further data theft and broader attacks within the cloud infrastructure. Therefore, it is recommended that IT, storage, or security teams, with assistance from development teams, personally configure each cloud bucket, ensuring proper access controls and avoiding default permissions. 8. Ensure compliance with regulatory requirements Most organizations today need to comply with strict regulatory requirements. This is especially important if you collect personally identifiable information (PII) or if your business is located in certain regions. Before you adopt a new cloud computing service, assess their compliance requirements and ensure they can fulfill data security needs. Failure to meet compliance requirements can lead to huge penalties. Other best practices for your cloud security include continuous monitoring and threat intelligence, data encryption at rest and in transit, and implementing intrusion detection and intrusion prevention systems. Conclusion When establishing a robust cloud security architecture, aligning business objectives and technical needs is important. Your organization must understand the shared responsibility model, risks, the appropriate implementation framework, and best practices. However, designing and developing cloud computing architectures can be complicated. Horizon ACE can secure your multi-cloud environment in minutes.

Let's break down the challenges: Hybrid is the new normal: Gartner predicts that by 2025, a whopping 90% of organizations will be running hybrid cloud environments. This means juggling the complexities of both on-premises and cloud security, demanding a broader skillset and a more holistic approach. Forget silos – we need to be fluent in both worlds. The skills gap is a chasm: (ISC)²'s 2022 Cybersecurity Workforce Study revealed a global cybersecurity workforce gap of 3.4 million. This talent shortage puts immense pressure on existing security professionals to do more with less. We're stretched thin, and something's gotta give. Threats are evolving faster than ever: The cloud introduces new attack vectors and vulnerabilities we haven't even imagined yet. McAfee reported a staggering 630% increase in cloud-native attacks in 2022. Staying ahead of these threats requires constant vigilance, continuous learning, and a proactive mindset. Level up your cloud security game So, how can you thrive in this chaotic environment and ensure your career (and your company's security posture) doesn't go down in flames? Here's your survival guide: Automate or die: Manual processes are a relic of the past. Embrace automation tools to manage complex security policies, respond to threats faster, and free up your time for strategic initiatives. Think of it as your force multiplier in the fight against complexity. Become a cloud-native ninja: Deepen your understanding of cloud platforms like AWS, Azure, and GCP. Master their security features, best practices, and quirks. The more you know, the more you can protect. Sharpen your soft skills: Technical chops alone won't cut it. Communication, collaboration, and problem-solving are critical. You need to clearly articulate security risks to stakeholders, build bridges with different teams, and drive solutions.

Uncategorized How To Prevent Firewall Breaches (The 2024 Guide) Tsippi Dach 2 min read Tsippi Dach Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 1/12/24 Published Properly configured firewalls are vital in any comprehensive cybersecurity strategy. However, even the most robust configurations can be vulnerable to exploitation by attackers. No single security measure can offer absolute protection against all cyber threats and data security risks . To mitigate these risks, it’s crucial to understand how cybercriminals exploit firewall vulnerabilities. The more you know about their tactics, techniques, and procedures, the better-equipped you are to implement security policies that successfully block unauthorized access to network assets. In this guide, you’ll understand the common cyber threats that target enterprise firewall systems with the goal of helping you understand how attackers exploit misconfigurations and human vulnerabilities. Use this information to protect your network from a firewall breach. Understanding 6 Tactics Cybercriminals Use to Breach Firewalls 1. DNS Leaks Your firewall’s primary use is making sure unauthorized users do not gain access to your private network and the sensitive information it contains. But firewall rules can go both ways – preventing sensitive data from leaving the network is just as important. If enterprise security teams neglect to configure their firewalls to inspect outgoing traffic, cybercriminals can intercept this traffic and use it to find gaps in your security systems. DNS traffic is particularly susceptible to this approach because it shows a list of websites users on your network regularly visit. A hacker could use this information to create a spoofed version of a frequently visited website. For example, they might notice your organization’s employees visit a third-party website to attend training webinars. Registering a fake version of the training website and collecting employee login credentials would be simple. If your firewall doesn’t inspect DNS data and confirm connections to new IP addresses, you may never know. DNS leaks may also reveal the IP addresses and endpoint metadata of the device used to make an outgoing connection. This would give cybercriminals the ability to see what kind of hardware your organization’s employees use to connect to external websites. With that information in hand, impersonating managed service providers or other third-party partners is easy. Some DNS leaks even contain timestamp data, telling attackers exactly when users requested access to external web assets. How to protect yourself against DNS leaks Proper firewall configuration is key to preventing DNS-related security incidents. Your organization’s firewalls should provide observability and access control to both incoming and outgoing traffic. Connections to servers known for hosting malware and cybercrime assets should be blocked entirely. Connections to servers without a known reputation should be monitored closely. In a Zero Trust environment , even connections to known servers should benefit from scrutiny using an identity-based security framework. Don’t forget that apps can connect to external resources, too. Consider deploying web application firewalls configured to prevent DNS leaks when connecting to third-party assets and servers. You may also wish to update your security policy to require employees to use VPNs when connecting to external resources. An encrypted VPN connection can prevent DNS information from leaking, making it much harder for cybercriminals to conduct reconnaissance on potential targets using DNS data. 2. Encrypted Injection Attacks Older, simpler firewalls analyze traffic by looking at different kinds of data packet metadata. This provides clear evidence of certain denial-of-service attacks, clear violations of network security policy , and some forms of malware and ransomware . They do not conduct deep packet inspection to identify the kind of content passing through the firewall. This provides cybercriminals with an easy way to bypass firewall rules and intrusion prevention systems – encryption . If malicious content is encrypted before it hits the firewall, it may go unnoticed by simple firewall rules. Only next-generation firewalls capable of handling encrypted data packets can determine whether this kind of traffic is secure or not. Cybercriminals often deliver encrypted injection attacks through email. Phishing emails may trick users into clicking on a malicious link that injects encrypted code into the endpoint device. The script won’t decode and run until after it passes the data security threshold posed by the firewall. After that, it is free to search for personal data, credit card information, and more. Many of these attacks will also bypass antivirus controls that don’t know how to handle encrypted data. Task automation solutions like Windows PowerShell are also susceptible to these kinds of attacks. Even sophisticated detection-based security solutions may fail to recognize encrypted injection attacks if they don’t have the keys necessary to decrypt incoming data. How to protect yourself against encrypted injection attacks Deep packet inspection is one of the most valuable features next-generation firewalls provide to security teams. Industry-leading firewall vendors equip their products with the ability to decrypt and inspect traffic. This allows the firewall to prevent malicious content from entering the network through encrypted traffic, and it can also prevent sensitive encrypted data – like login credentials – from leaving the network. These capabilities are unique to next-generation firewalls and can’t be easily replaced with other solutions. Manufacturers and developers have to equip their firewalls with public-key cryptography capabilities and obtain data from certificate authorities in order to inspect encrypted traffic and do this. 3. Compromised Public Wi-Fi Public Wi-Fi networks are a well-known security threat for individuals and organizations alike. Anyone who logs into a password-protected account on public Wi-Fi at an airport or coffee shop runs the risk of sending their authentication information directly to hackers. Compromised public Wi-Fi also presents a lesser-known threat to security teams at enterprise organizations – it may help hackers breach firewalls. If a remote employee logs into a business account or other asset from a compromised public Wi-Fi connection, hackers can see all the data transmitted through that connection. This may give them the ability to steal account login details or spoof endpoint devices and defeat multi-factor authentication. Even password-protected private Wi-Fi connections can be abused in this way. Some Wi-Fi networks still use outdated WEP and WPA security protocols that have well-known vulnerabilities. Exploiting these weaknesses to take control of a WEP or WPA-protected network is trivial for hackers. The newer WPA2 and WPA3 standards are much more resilient against these kinds of attacks. While public Wi-Fi dangers usually bring remote workers and third-party service vendors to mind, on-premises networks are just as susceptible. Nothing prevents a hacker from gaining access to public Wi-Fi networks in retail stores, receptions, or other areas frequented by customers and employees. How to protect yourself against compromised public Wi-Fi attacks First, you must enforce security policies that only allow Wi-Fi traffic secured by WPA2 and WPA3 protocols. Hardware Wi-Fi routers that do not support these protocols must be replaced. This grants a minimum level of security to protected Wi-Fi networks. Next, all remote connections made over public Wi-Fi networks must be made using a secure VPN. This will encrypt the data that the public Wi-Fi router handles, making it impossible for a hacker to intercept without gaining access to the VPN’s secret decryption key. This doesn’t guarantee your network will be safe from attacks, but it improves your security posture considerably. 4. IoT Infrastructure Attacks Smartwatches, voice-operated speakers, and many automated office products make up the Internet of Things (IoT) segment of your network. Your organization may be using cloud-enriched access control systems, cost-efficient smart heating systems, and much more. Any Wi-Fi-enabled hardware capable of automation can safely be included in this category. However, these devices often fly under the radar of security team’s detection tools, which often focus on user traffic. If hackers compromise one of these devices, they may be able to move laterally through the network until they arrive at a segment that handles sensitive information. This process can take time, which is why many incident response teams do not consider suspicious IoT traffic to be a high-severity issue. IoT endpoints themselves rarely process sensitive data on their own, so it’s easy to overlook potential vulnerabilities and even ignore active attacks as long as the organization’s mission-critical assets aren’t impacted. However, hackers can expand their control over IoT devices and transform them into botnets capable of running denial-of-service attacks. These distributed denial-of-service (DDoS) attacks are much larger and more dangerous, and they are growing in popularity among cybercriminals. Botnet traffic associated with DDoS attacks on IoT networks has increased five-fold over the past year , showing just how promising it is for hackers. How to protect yourself against IoT infrastructure attacks Proper network segmentation is vital for preventing IoT infrastructure attacks . Your organization’s IoT devices should be secured on a network segment that is isolated from the rest of the network. If attackers do compromise the entire network, you should be protected from the risk of losing sensitive data from critical business assets. Ideally, this protection will be enforced with a strong set of firewalls managing the connection between your IoT subnetwork and the rest of your network. You may need to create custom rules that take your unique security risk profile and fleet of internet-connected devices into account. There are very few situations in which one-size-fits-all rulemaking works, and this is not one of them. All IoT devices – no matter how small or insignificant – should be protected by your firewall and other cybersecurity solutions . Never let these devices connect directly to the Internet through an unsecured channel. If they do, they provide attackers with a clear path to circumvent your firewalls and gain access to the rest of your network with ease. 5. Social Engineering and Phishing Social engineering attacks refer to a broad range of deceptive practices used by hackers to gain access to victims’ assets. What makes this approach special is that it does not necessarily depend on technical expertise. Instead of trying to hack your systems, cybercriminals are trying to hack your employees and company policies to carry out their attacks. Email phishing is one of the most common examples. In a typical phishing attack , hackers may spoof an email server to make it look like they are sending emails from a high-level executive in the company you work for. They can then impersonate this executive and demand junior accountants pay fictitious invoices or send sensitive customer data to email accounts controlled by threat actors. Other forms of social engineering can use your organization’s tech support line against itself. Attackers may pretend to represent large customer accounts and will leverage this ruse to gain information about how your company works. They may impersonate a third-party vendor and request confidential information that the vendor would normally have access to. These attacks span the range from simple trickery to elaborate confidence scams. Protecting against them can be incredibly challenging, and your firewall capabilities can make a significant difference in your overall state of readiness. How to protect yourself against social engineering attacks Employee training is the top priority for protecting against social engineering attacks . When employees understand the company’s operating procedures and security policies, it’s much harder for social engineers to trick them. Ideally, training should also include in-depth examples of how phishing attacks work, what they look like, and what steps employees should take when contacted by people they don’t trust. 6. Sandbox Exploits Many organizations use sandbox solutions to prevent file-based malware attacks. Sandboxes work by taking suspicious files and email attachments and opening them in a secure virtual environment before releasing them to users. The sandbox solution will observe how the file behaves and quarantine any file that shows malicious activity. In theory, this provides a powerful layer of defense against file-based attacks. But in practice, cybercriminals are well aware of how to bypass these solutions. For example, many sandbox solutions can’t open files over a certain size. Hackers who attach malicious code to large files can easily get through. Additionally, many forms of malware do not start executing malicious tasks the second they are activated. This delay can provide just enough of a buffer to get through a sandbox system. Some sophisticated forms of malware can even detect when they are being run in a sandbox environment – and will play the part of an innocent program until they are let loose inside the network. How to protect yourself against sandbox exploits Many next-generation firewalls include cloud-enabled sandboxing capable of running programs of arbitrary size for a potentially unlimited amount of time. More sophisticated sandbox solutions go to great lengths to mimic the system specifications of an actual endpoint so malware won’t know it is being run in a virtual environment. Organizations may also be able to overcome the limitations of the sandbox approach using Content Disarm and Reconstruction (CDR) techniques. This approach keeps potentially malicious files off the network entirely and only allows a reconstructed version of the file to enter the network. Since the new file is constructed from scratch, it will not contain any malware that may have been attached to the original file.

Security Policy Management Deploying NSPM to Implement a Gartner Analyst’s Work from Home Network Security Advice Jeffrey Starr 2 min read Jeffrey Starr Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 4/27/20 Published Recommendations from Rajpreet Kaur, Senior Principal Analyst at Gartner, in her recent blog on remote working, and a perspective on how Network Security Policy Management systems can help enterprises act upon this guidance The COVID-19 pandemic has been the catalyst for a global migration to remote home working. Managing and mitigating the network security risks this presents, on such an unprecedented scale and for a long period of time, poses a significant challenge even for companies that had remote access working plans in place before the pandemic. Not only are cybercriminals taking advantage of network insecurities to leverage attacks, they are also exploiting human anxiety around the crisis to break through security barriers. In fact, a recent survey found that 40 percent of companies reported seeing increased cyberattacks as they enable remote working. So how should organizations manage their security during these massive changes in network usage? In a recent blog , Rajpreet Kaur , Gartner Senior Principal Analyst, and a specialized expert on both hybrid environment network security and NSPM tools, offered recommendations to organizations on how to handle remote infrastructure security challenges, many of which closely align with a focus on network policy automation and application security. Here’s how network security policy management systems can support and enable Rajpreet Kaur’s key recommendations. 1. Don’t panic and start moving things to the cloud without a proper architectural design in place. Panicking and starting a large-scale move to the cloud without a proper plan in place can lead to poor security controls and ill-prepared migration. Before moving to the cloud, organizations must consider their network’s architectural design, which should always start with analysis. The analytical and discovery capabilities of NSPM systems automate this process by discovering and mapping network connectivity and providing a network map, which helps you to understand your network components, making migrations easier, faster and glitch-free. 2. Design a proper network security architecture and plan considering limited disruption and supporting work from home. Implementing these immediate and urgent network changes can only be done effectively and securely with robust change management processes. As with network analysis, NSPM automation capabilities are also vital in rapid change management. Security automation dramatically accelerates change processes, with request generation to implementation time drastically shortened and enables better enforcement and auditing for regulatory compliance. It also helps organizations overcome skill gaps and staffing limitations, which may have already been impacted by the current crisis. NSPM solutions enable full end-to-end change analysis and automation, including what if security checks, automation design, push of changes, and full documentation and audit trail. This ensures that changes can be implemented rapidly, and applied consistently and efficiently, with a full audit trail of every change. 3. Plan for what you need now, don’t try to implement a long-term strategic solution to fix your immediate needs. The current widespread move to home working is adding an extra layer of complexity to remote network security, since organizations are finding themselves having to implement new security policies and roll out adoption in a very short timeframe. Considering this, it’s important for organizations to focus on short-term needs, rather than attempting to develop a long-term strategic solution. Trying to develop a long-term solution in such a short window can be overwhelming and increase the risk of opening security vulnerabilities. Using NSPM speeds up the configuration and implementation process, allowing you to get your remote network security firewall policies up and running as soon as possible, with minimum disruption to your remote workforce. Once you have dealt with the critical immediate needs, you can then focus on developing a more long-term strategy. 4. Try to support your existing work from home employees by doing minimal changes to the existing architecture, like meeting throughput requirements and upgrading the equipment or restricting the access to a group of employees at times. Managing application connectivity and accessibility is key to ensuring minimal work disruption as employees move to remote working. An effective NSPM solution allows you to discover, identify and map business applications to ensure that they are safe and have the necessary connectivity flows. Having such a view of all the applications that are accessing the network allows security teams to map the workflow and provides visibility of the application’s required connectivity in order to minimise outages. 5. For any new network changes and upgrades, or new deployments, consider developing a work from home first strategy. Developing a work from home (WFH) strategy has never been more essential. The challenge is that WFH is a more vulnerable environment; employees are accessing sensitive data from a range of home devices, via outside networks, that may not have the same security controls. On top of this, cyber threats have already seen a sharp increase as cybercriminals exploit the widespread anxiety and vulnerabilities caused by the global crisis. IT security and networking staff are therefore having to do more, with the same staffing levels, whilst also navigating the challenges of doing this remotely from home. NSPM capabilities can help in overcoming these WFH issues. Security teams may, for example, need to change many Firewall rules to allow secure access to sensitive data. An effective NSPM solution can facilitate this and enable fast deployment by providing the ability to make changes to applications’ firewall openings from a single management interface. 6. Enhance security around public facing applications to protect against COVID-19 related cyber-attacks. With the move to remote working, organizations are increasingly relying on applications to carry out their work from home. Ensuring that business-critical applications stay available and secure while shifting to remote work is key to avoiding workflow disruption. It’s essential to take an application centric approach to application security, and an effective NSPM solution can help you to better manage and secure your business-critical applications . As discussed above, application visibility is key here. NSPM systems provides comprehensive application visibility, security operation teams can monitor critical applications for risks and vulnerabilities to ensure that they are safe. Gartner’s Rajpreet Kaur has delivered a good combination of practical and timely guidance along with the logical insights underlying the useful recommendations. These tips bring helpful guidance on the Work from Home security challenge that stands out for its clear relevance when there is now so much other noise out there. A robust NSPM can help you rapidly implement these invaluable recommendations. Schedule a demo Related Articles Q1 at AlgoSec: What innovations and milestones defined our start to 2026?

Network Segmentation Host-based firewalls vs. network-based firewalls for network security? Prof. Avishai Wool 2 min read Prof. Avishai Wool Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 8/28/23 Published Before your organization can move business applications to the cloud, it must deploy network security solutions that can reliably block cybercrime and malware. Firewalls are essential cybersecurity tools that protect network traffic against threat actors. There are many different types of firewalls available, but put the same basic principles in action. Before finding out which types of firewalls offer the best security performance for your cloud implementation, it’s important to cover how firewalls work and what characteristics set them apart. How firewalls work: Different types of firewalls explained Firewalls are best explained through analogy. Think of firewalls as 24/7 security guards with deep knowledge of millions of criminals. Whenever the security guard sees a criminal approaching an access point, they block access and turn the criminal away. This kind of access control is accomplished in a few different ways. Some firewalls inspect packets for suspicious characteristics. Others use stateful inspection to identify malicious traffic. Some incorporate contextual awareness to tell the difference between harmless traffic and cyberattacks . Here are some of the major types of firewalls and how they work: Packet filtering firewalls inspect data traveling through inline junction points like routers and switches. They don’t route data packets themselves, but compare them to a list of firewall rules. For example, they may filter packets that are traveling to untrusted IP addresses and drop them. Circuit-level gateways monitor TCP handshake data and other protocol messages for signs of unauthorized access. These firewalls don’t inspect individual packets or application layer monitoring, though. Proxy firewalls apply application layer filtering that filters data according to a wide range of characteristics. This category includes web application firewalls, which are a type of reverse proxy firewall – they protect the server from malicious traffic by filtering clients before they reach the server. Stateful inspection firewalls examine and compare multiple packets to find out if they are part of an established network session. This offers a high degree of control over incoming and outgoing traffic while providing comprehensive logs on network connections. Next-generation firewalls combine packet inspection, stateful inspection, antivirus, and additional technologies to protect organizations against unknown threats and vulnerabilities. These firewalls are expensive and have high bandwidth requirements, but they also offer a high level of protection. All of these firewalls exist in different forms. Traditional hardware firewalls are physical devices that sit between network devices and the internet. Network-based firewalls are software-defined apps designed to do the same thing. Hardware, software, or cloud? firewall deployment methods compared Organizations have multiple options when deciding to host firewalls on their private networks. The market offers a vast number of security devices and firewall providers, ranging from Cisco hardware to software solutions like Microsoft’s Windows firewall. Large enterprises use a combination of firewall solutions to adopt a multi-layered security posture. This allows them to achieve network scalability and segmentation while offering different levels of protection to data centers, individual devices, and user endpoints. As firewall technology becomes more accessible, smaller organizations are following suit. Here are some of the delivery formats that firewall solutions commonly come in: Network-based Firewalls are self-contained hardware appliances. They typically run custom operating systems using Linux distributions designed for secure computer networking. They can be challenging to configure and deploy, but are appropriate for a wide range of use cases. Host-based Firewalls run as software on a server or other device. You can run host-based firewalls on individual computers, or at the host level of a cloud environment. The firewalls offer granular control over security rules and individual hosts, but consume resources in the process. Cloud Hosted Firewalls are provided by third-party security partners as a service. These firewalls may be entirely managed by a third-party partner, making them ideal for small organizations that can’t afford building their own security infrastructure from the ground up. How to select an optimal firewall solution for your organization Every organization has a unique security risk profile. Finding the right firewall deployment for your organization requires in-depth knowledge of your network’s security vulnerabilities and potential for long-term growth. Some of the issues you have to consider include: Identifying technical objectives for individual firewalls. There are no one-size-fits-all firewall solutions. One solution may match a particular use case that another does not. Both stateless packet inspection firewalls and sophisticated next-generation solutions operate at different levels of the OSI model, which means each device should serve a well-defined purpose. Selecting firewall solutions that match your team’s expertise. Consider your IT team’s technical qualifications. If configuring a sophisticated next-generation firewall requires adding talent with specialized certifications to your team, the cost of that deployment will rise considerably. Deploying firewalls in ways that improve security performance while reducing waste. Optimal firewall architecture requires effective network segmentation and good security policies. Deploying a secure local area network (LAN) and using virtual private networks (VPNs) can help optimize firewall placement throughout the organization. Determining which kinds of traffic inspection are necessary. Different types of network connections require different levels of security. For example, a public-facing Wi-Fi router is far more likely to encounter malicious traffic than an internal virtual local area network (VLAN) that only authenticated employees can access. How to choose between host-based firewalls and network-based firewalls when moving to the cloud Organizations that are transitioning to cloud infrastructure need to completely rethink their firewall deployment strategy. Firewalls are the cornerstone of access control, and cloud-hosted infrastructure comes with the shared responsibility model that puts pressure on security leaders to carefully deploy security resources. In many cases, you’ll face tough decisions concerning which type of firewall to deploy at particular points in your network. Building an optimal deployment means working through the pros and cons of each option on a case-by-case basis. Host-based firewalls and network-based firewalls are the two main options you’ll encounter for most use cases. Let’s look at what each of those options look like from a complete network security perspective . 1. Host-based firewalls offer flexibility but may introduce vulnerabilities A cloud-native organization that exclusively uses host-based firewalls will have a cloud environment filled with virtual machines that take the place of servers and individual computers. To protect those devices, the organization will implement host-based firewalls on every virtual machine and configure them accordingly. This provides the organization with a great deal of flexibility. IT team members can clone virtual machines and move them within the cloud on demand. The host-based firewalls that protect these machines can move right alongside them, ensuring consistent security policies are enforced without painstaking manual configuration. It’s even possible to move virtual machines between cloud environments – like moving a virtual server from Amazon AWS to Microsoft Azure – without having to create completely new security policies in the process. This makes it easy for IT teams to work securely without introducing friction. However, if attackers gain privileged access to host-based firewalls, they gain the same level of control. They may switch off the firewall or install malicious code in ways that other security technologies cannot detect. Even highly secure organizations are subject to this kind of risk. Imagine an attacker compromises the credentials of a system administrator with firewall configuration privileges. Very few obstacles stand between an insider threat and the sensitive data they wish to exfiltrate. Network-based firewalls offer independent security Compared to host-based firewall products, it’s much harder for a malicious insider to compromise a network-based firewall solution managed by a cloud provider. That’s because the physical hardware is operating on a completely separate system from the host. In a cloud-native environment, the network-based firewall would be a fully hardened device managed by a third-party provider running their own intrusion detection systems. This makes it much harder for attackers to successfully infiltrate and compromise systems without being noticed. At the same time, independent network-based firewall architecture means that the attacker would have to compromise both your network and the cloud provider’s network without triggering security alerts from either. This adds a great deal of complexity to any attack, and significantly increases the chance it will be detected. However, few organizations can afford to exclusively deploy hardware firewalls at every layer of their network. Even those that can afford it will run into significant challenges when planning for growth and scalability. Segment your network for optimal protection While they offer increased security, hardware firewalls are costly to deploy and maintain. Most organizations segment their networks in ways that offer extensive multi-layered protection to their most sensitive data while allowing more flexible host-based firewalls to protect less critical assets. Every organization has a unique balance between optimal network-based firewall and host-based firewall deployment. This depends heavily on the volume of sensitive data the organization regularly accesses, and the security of its connections with users and third-party service providers. Proper network segmentation helps reduce the organization’s attack surface and decrease the risk of business disruption.
