Tags Share this article 11/24/22 Published Multi-cloud environments create complex IT architectures that are hard to secure. Although cloud computing creates numerous advantages for companies, it also increases the risk of data breaches. Did you know that you can mitigate these risks with a CSPM? Rony Moshkovitch, Prevasio’s co-founder, discusses why modern organizations need to opt for a CSPM solution when migrating to the cloud and also offers three powerful tips to finding and implementing the right one. Cloud Security Can Get Messy if You Let it A cloud-based IT infrastructure can lower your IT costs, boost your agility, flexibility, and scalability, and enhance business resilience. These great advantages notwithstanding, the cloud also has one serious drawback: it is not easy to secure. When you move from an on-premise infrastructure to the cloud, the size of your digital footprint expands. This can attract hackers on the prowl who are looking for the first opportunity to compromise your assets or steal your data. Cloud security solutions include multiple elements that must be managed and protected, such as microservices, containers, and serverless functions. These elements increase cloud complexity, reduce visibility into the cloud estate, and make it harder to secure. For all these reasons, security issues arise in the cloud, increasing the risk of breaches that may result in financial losses, legal liabilities, or reputational damage. To protect the complex and fluid cloud environment, sophisticated automation is essential. Enter cloud security posture management. How to Identify and Implement the Right CSPM Solution 1) It must offer a flat learning curve to accelerate time to value: The CSPM solution can be easy to implement, adopt, and use. It should not burden your security team. Rather, it should simplify cloud security by providing non-intrusive, agentless scans of all cloud accounts, services, and assets. It should also provide actionable information in a single-pane-of-glass view that clearly reveals what needs to be remediated in order to strengthen your cloud security posture. In addition, the solution should generate reports that are easy to understand and share. 2) It must support non-intrusive, agentless, static and dynamic analyses: Some CSPM solutions only support static scans, leaving dynamic scans to other intrusive solutions. The problem with the latter is that they require agents to be deployed, managed, and updated for every scan, increasing the organization’s technical debt and forcing security teams to spend expensive (and scarce) resources on solution management. The best way to minimize the debt and the management burden on security teams is to choose a CSPM that can scan for threats in an agentless manner. It should also perform agentless dynamic analyses on all container applications and images that can reveal valuable information about exposed network ports and other risks. 3) It must be reasonably priced: CSPM is important but it shouldn’t burn a hole in your pocket. The solution should fit your security budget and match your organization’s size, cloud environment complexity, and cloud asset usage. Also, look for a vendor that provides a transparent license model and dynamic security features instead of just dynamic, expensive billing (that could reduce your ability to control your cloud costs). Conclusion and next steps The global CSPM market is set to double from $4.2 billion in 2022 to $8.6 billion by 2027. Already, many CSPM vendors and solutions are available. In order to select the best solution for your organization, make sure to consider the three tips discussed here. Need more tailored advice about the security needs of your enterprise cloud?

Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 7/21/23 Published A Comprehensive Cloud Security Checklist for Your Cloud Environment There’s a lot to consider when securing your cloud environment. Threats range from malware to malicious attacks, and everything in between. With so many threats, a checklist of cloud security best practices will save you time. First we’ll get a grounding in the top cloud security risks and some key considerations. The Top 5 Security Risks in Cloud Computing Understanding the risks involved in cloud computing is a key first step. The top 5 security risks in cloud computing are: 1. Limited visibility Less visibility means less control. Less control could lead to unauthorized practices going unnoticed. 2. Malware Malware is malicious software, including viruses, ransomware, spyware, and others. 3. Data breaches Breaches can lead to financial losses due to regulatory fines and compensation. They may also cause reputational damage. 4. Data loss The consequences of data loss can be severe, especially it includes customer information. 5. Inadequate cloud security controls If cloud security measures aren’t comprehensive, they can leave you vulnerable to cyberattacks. Key Cloud Security Checklist Considerations 1. Managing User Access and Privileges Properly managing user access and privileges is a critical aspect of cloud infrastructure. Strong access controls mean only the right people can access sensitive data. 2. Preventing Unauthorized Access Implementing stringent security measures, such as firewalls, helps fortify your environment. 3. Encrypting Cloud-Based Data Assets Encryption ensures that data is unreadable to unauthorized parties. 4. Ensuring Compliance Compliance with industry regulations and data protection standards is crucial. 5. Preventing Data Loss Regularly backing up your data helps reduce the impact of unforeseen incidents. 6. Monitoring for Attacks Security monitoring tools can proactively identify suspicious activities, and respond quickly. Cloud Security Checklist Understand cloud security risks Establish a shared responsibility agreement with your cloud services provider (CSP) Establish cloud data protection policies Set identity and access management rules Set data-sharing restrictions Encrypt sensitive data Employ a comprehensive data backup and recovery plan Use malware protection Create an update and patching schedule Regularly assess cloud security Set up security monitoring and logging Adjust cloud security policies as new issues emerge Let’s take a look at these in more detail. Full Cloud Security Checklist 1. Understand Cloud Security Risks 1a. Identify Sensitive Information First, identify all your sensitive information. This data could range from customer information to patents, designs, and trade secrets. 1b. Understand Data Access and Sharing Use access control measures, like role-based access control (RBAC), to manage data access. You should also understand and control how data is shared. One idea is to use data loss prevention (DLP) tools to prevent unauthorized data transfers. 1c. Explore Shadow IT Shadow IT refers to using IT tools and services without your company’s approval. While these tools can be more productive or convenient, they can pose security risks. 2. Establish a Shared Responsibility Agreement with Your Cloud Service Provider (CSP) Understanding the shared responsibility model in cloud security is essential. There are various models – IaaS, PaaS, or SaaS. Common CSPs include Microsoft Azure and AWS. 2a. Establish Visibility and Control It’s important to establish strong visibility into your operations and endpoints. This includes understanding user activities, resource usage, and security events. Using security tools gives you a centralized view of your secure cloud environment. You can even enable real-time monitoring and prompt responses to suspicious activities. Cloud Access Security Brokers (CASBs) or cloud-native security tools can be useful here. 2b. Ensure Compliance Compliance with relevant laws and regulations is fundamental. This could range from data protection laws to industry-specific regulations. 2c. Incident Management Despite your best efforts, security incidents can still occur. Having an incident response plan is a key element in managing the impact of any security events. This plan should tell team members how to respond to an incident. 3. Establish Cloud Data Protection Policies Create clear policies around data protection in the cloud . These should cover areas such as data classification, encryption, and access control. These policies should align with your organizational objectives and comply with relevant regulations. 3a. Data Classification You should categorize data based on its sensitivity and potential impact if breached. Typical classifications include public, internal, confidential, and restricted data. 3b. Data Encryption Encryption protects your data in the cloud and on-premises. It involves converting your data so it can only be read by those who possess the decryption key. Your policy should mandate the use of strong encryption for sensitive data. 3c. Access Control Each user should only have the access necessary to perform their job function and no more. Policies should include password policies and changes of workloads. 4. Set Identity and Access Management Rules 4a. User Identity Management Identity and Access Management tools ensure only the right people access your data. Using IAM rules is critical to controlling who has access to your cloud resources. These rules should be regularly updated. 4b. 2-Factor and Multi-Factor Authentication Two-factor authentication (2FA) and multi-factor authentication (MFA) are useful tools. You reduce the risk by implementing 2FA or MFA, even if a password is compromised. 5. Set Data Sharing Restrictions 5a. Define Data Sharing Policies Define clear data-sharing permissions. These policies should align with the principles of least privilege and need-to-know basis. 5b. Implement Data Loss Prevention (DLP) Measures Data Loss Prevention (DLP) tools can help enforce data-sharing policies. These tools monitor and control data movements in your cloud environment. 5c. Audit and Review Data Sharing Activities Regularly review and audit your data-sharing activities to ensure compliance. Audits help identify any inappropriate data sharing and provide insights for improvement. 6. Encrypt Sensitive Data Data encryption plays a pivotal role in safeguarding your sensitive information. It involves converting your data into a coded form that can only be read after it’s been decrypted. 6a. Protect Data at Rest This involves transforming data into a scrambled form while it’s in storage. It ensures that even if your storage is compromised, the data remains unintelligible. 6b. Data Encryption in Transit This ensures that your sensitive data remains secure while it’s being moved. This could be across the internet, over a network, or between components in a system. 6c. Key Management Managing your encryption keys is just as important as encrypting the data itself. Keys should be stored securely and rotated regularly. Additionally, consider using hardware security modules (HSMs) for key storage. 6d. Choose Strong Encryption Algorithms The strength of your encryption depends significantly on the algorithms you use. Choose well-established encryption algorithms. Advanced Encryption Standard (AES) or RSA are solid algorithms. 7. Employ a Comprehensive Data Backup and Recovery Plan 7a. Establish a Regular Backup Schedule Install a regular backup schedule that fits your organization’s needs . The frequency of backups may depend on how often your data changes. 7b. Choose Suitable Backup Methods You can choose from backup methods such as snapshots, replication, or traditional backups. Each method has its own benefits and limitations. 7c. Implement a Data Recovery Strategy In addition to backing up your data, you need a solid strategy for restoring that data if a loss occurs. This includes determining recovery objectives. 7d. Test Your Backup and Recovery Plan Regular testing is crucial to ensuring your backup and recovery plan works. Test different scenarios, such as recovering a single file or a whole system. 7e. Secure Your Backups Backups can become cybercriminals’ targets, so they also need to be secured. This includes using encryption to protect backup data and implementing access controls. 8. Use Malware Protection Implementing robust malware protection measures is pivotal in data security. It’s important to maintain up-to-date malware protection and routinely scan your systems. 8a. Deploy Antimalware Software Deploy antimalware software across your cloud environment. This software can detect, quarantine, and eliminate malware threats. Ensure the software you select can protect against a wide range of malware. 8b. Regularly Update Malware Definitions Anti-malware relies on malware definitions. However, cybercriminals continuously create new malware variants, so these definitions become outdated quickly. Ensure your software is set to automatically update. 8c. Conduct Regular Malware Scans Schedule regular malware scans to identify and mitigate threats promptly. This includes full system scans and real-time scanning. 8d. Implement a Malware Response Plan Develop a comprehensive malware response plan to ensure you can address any threats. Train your staff on this plan to respond efficiently during a malware attack. 8e. Monitor for Anomalous Activity Continuously monitor your systems for any anomalous activity. Early detection can significantly reduce the potential damage caused by malware. 9. Create an Update and Patching Schedule 9a. Develop a Regular Patching Schedule Develop a consistent schedule for applying patches and updates to your cloud applications. For high-risk vulnerabilities, consider implementing patches as soon as they become available. 9b. Maintain an Inventory of Software and Systems You need an accurate inventory of all software and systems to manage updates and patches. This inventory should include the system version, last update, and any known vulnerabilities. 9c. Automation Where Possible Automating the patching process can help ensure that updates are applied consistently. Many cloud service providers offer tools or services that can automate patch management. 9d. Test Patches Before Deployment Test updates in a controlled environment to ensure work as intended. This is especially important for patches to critical systems. 9e. Stay Informed About New Vulnerabilities and Patches Keep abreast of new vulnerabilities and patches related to your software and systems. Being aware of the latest threats and solutions can help you respond faster. 9f. Update Security Tools and Configurations Don’t forget to update your cloud security tools and configurations regularly. As your cloud environment evolves, your security needs may change. 10. Regularly Assess Cloud Security 10a. Set up cloud security assessments and audits Establish a consistent schedule for conducting cybersecurity assessments and security audits. Audits are necessary to confirm that your security responsibilities align with your policies. These should examine configurations, security controls, data protection and incident response plans. 10b. Conduct Penetration Testing Penetration testing is a proactive approach to identifying vulnerabilities in your cloud environment. These are designed to uncover potential weaknesses before malicious actors do. 10c. Perform Risk Assessments These assessments should cover a variety of technical, procedural, and human risks. Use risk assessment results to prioritize your security efforts. 10d. Address Assessment Findings After conducting an assessment or audit, review the findings and take appropriate action. It’s essential to communicate any changes effectively to all relevant personnel. 10f. Maintain Documentation Keep thorough documentation of each assessment or audit. Include the scope, process, findings, and actions taken in response. 11. Set Up Security Monitoring and Logging 11a. Intrusion Detection Establish intrusion detection systems (IDS) to monitor your cloud environment. IDSs operate by recognizing patterns or anomalies that could indicate unauthorized intrusions. 11b. Network Firewall Firewalls are key components of network security. They serve as a barrier between secure internal network traffic and external networks. 11c. Security Logging Implement extensive security logging across your cloud environment. Logs record the events that occur within your systems. 11d. Automate Security Alerts Consider automating security alerts based on triggering events or anomalies in your logs. Automated alerts can ensure that your security team responds promptly. 11e. Implement Information Security and Event Management (SIEM) System A Security Information and Event Management (SIEM) system can your cloud data. It can help identify patterns, security breaches, and generate alerts. It will give a holistic view of your security posture. 11f. Regular Review and Maintenance Regularly review your monitoring and logging practices to ensure they remain effective. as your cloud environment and the threat landscape evolve. 12. Adjust Cloud Security Policies as New Issues Emerge 12a. Regular Policy Reviews Establish a schedule for regular review of your cloud security policies. Regular inspections allow for timely updates to keep your policies effective and relevant. 12b. Reactive Policy Adjustments In response to emerging threats or incidents, it may be necessary to adjust on an as-needed basis. Reactive adjustments can help you respond to changes in the risk environment. 12c. Proactive Policy Adjustments Proactive policy adjustments involve anticipating future changes and modifying your policies accordingly. 12d. Stakeholder Engagement Engage relevant stakeholders in the policy review and adjustment process. This can include IT staff, security personnel, management, and even end-users. Different perspectives can provide valuable insights. 12e. Training and Communication It’s essential to communicate changes whenever you adjust your cloud security policies. Provide training if necessary to ensure everyone understands the updated policies. 12f. Documentation and Compliance Document any policy adjustments and ensure they are in line with regulatory requirements. Updated documentation can serve as a reference for future reviews and adjustments.

Avishai Wool, CTO and co-founder of AlgoSec, looks at how organizations can implement and manage SDN-enabled micro-segmentation... Micro-segmentation Building a Blueprint for a Successful Micro-segmentation Implementation 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 6/22/20 Published Avishai Wool, CTO and co-founder of AlgoSec, looks at how organizations can implement and manage SDN-enabled micro-segmentation strategies Micro-segmentation is regarded as one of the most effective methods to reduce an organization’s attack surface, and a lack of it has often been cited as a contributing factor in some of the largest data breaches and ransomware attacks. One of the key reasons why enterprises have been slow to embrace it is because it can be complex and costly to implement – especially in traditional on-premise networks and data centers. In these, creating internal zones usually means installing extra firewalls, changing routing, and even adding cabling to police the traffic flows between zones, and having to manage the additional filtering policies manually. However, as many organizations are moving to virtualized data centers using Software-Defined Networking (SDN), some of these cost and complexity barriers are lifted. In SDN-based data centers the networking fabric has built-in filtering capabilities, making internal network segmentation much more accessible without having to add new hardware. SDN’s flexibility enables advanced, granular zoning: In principle, data center networks can be divided into hundreds, or even thousands, of microsegments. This offers levels of security that would previously have been impossible – or at least prohibitively expensive – to implement in traditional data centers. However, capitalizing on the potential of micro-segmentation in virtualized data centers does not eliminate all the challenges. It still requires the organization to deploy a filtering policy that the micro-segmented fabric will enforce, and writing this a policy is the first, and largest, hurdle that must be cleared. The requirements from a micro-segmentation policy A correct micro-segmentation filtering policy has three high-level requirements: It allows all business traffic – The last thing you want is to write a micro-segmented policy and have it block necessary business communication, causing applications to stop functioning. It allows nothing else – By default, all other traffic should be denied. It is future-proof – ‘More of the same’ changes in the network environment shouldn’t break rules. If you write your policies too narrowly, when something in the network changes, such as a new server or application, something will stop working. Write with scalability in mind. A micro-segmentation blueprint Now that you know what you are aiming for, how can you actually achieve it? First of all, your organization needs to know what your traffic flows are – what is the traffic that should be allowed. To get this information, you can perform a ‘discovery’ process. Only once you have this information, can you then establish where to place the borders between the microsegments in the data center and how to devise and manage the security policies for each of the segments in their network environment. I welcome you to download AlgoSec’s new eBook , where we explain in detail how to implement and manage micro-segmentation. AlgoSec Enables Micro-segmentation The AlgoSec Security Management Suite (ASMS) employs the power of automation to make it easy to define and enforce your micro-segmentation strategy inside the data center, ensure that it does not block critical business services, and meet compliance requirements. AlgoSec supports micro-segmentation by: Providing application discovery based on netflow information Identifying unprotected network flows that do not cross any firewall and are not filtered for an application Automatically identifying changes that will violate the micro-segmentation strategy Automatically implementing network security changes Automatically validating changes The bottom line is that implementing an effective network micro-segmentation strategy is now possible. It requires careful planning and implementation, but when carried out following a proper blueprint and with the automation capabilities of the AlgoSec Security Management Suite, it provides you with stronger security without sacrificing any business agility.

As you may have heard already, the National Security Agency (NSA) and the Federal Bureau of Investigation (FBI) released a joint... Cloud Security Drovorub’s Ability to Conceal C2 Traffic And Its Implications For Docker Containers Rony Moshkovich 2 min read Rony Moshkovich 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 8/15/20 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.

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.

Cloud Security Understanding and Preventing Kubernetes Attacks and Threats Ava Chawla 2 min read Ava Chawla 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 10/20/21 Published As the most widely adapted open-source container software, Kubernetes provides businesses with efficient processes to schedule, deploy, and scale containers across different machines. The bad news is that cybercriminals have figured out how to exploit the platform’s vulnerabilities , resulting in catastrophic network intrusions across many company infrastructures. A recent report revealed that 94% of respondents reported security incidents in Kubernetes environments. The question is, what is behind this surge of Kubernetes attacks, and how can they be prevented? How Kubernetes is Vulnerable As a container-based platform, a new set of vulnerabilities, permission issues, and specific images set the stage for the increase in attacks. The threats have included fileless malware in containers, leveraging misconfigured Docker API ports, and using container images for attacks. Misconfigured Docker API Ports Exploitation Scanning for misconfigured Docker API ports and using them for deploying images containing malware is a relatively new type of attack. The malware, designed to evade static scanning, has become a popular method to hijack compute cycles for fraudulent cryptomining. This cryptojacking activity steals CPU power to mine currencies such as Ethereum and Monero. By first identifying vulnerable front-end websites and other systems, attackers send a command through the application layer simply by manipulating a domain’s text field or through an exposed API in the website’s URL. The code then enters the container, where it is executed with commands sent to a Docker container’s shell. A wget command is executed to download the malware. To protect against this attack, enterprises must ensure their container files are not writable, establish CPU consumption limits, and enable alerts to detect interactive shell launches. DDoS Attacks With Open Docker Daemons Cybercriminals use misconfigured open Docker daemons to launch DDoS attacks using a botnet of containers. UDP flood and Slowloris were recently identified as two such types of container-based botnet attacks. A recent blog describes an anatomy of these Kubernetes attacks. The attackers first identified open Docker daemons using a scanning tool such as Shodan to scan the internet for IP addresses and find a list of hosts, open ports, and services. By uploading their own dedicated images to the Docker hub, they succeeded in deploying and remotely running the images on the host. Analyzing how the UDP flood attack was orchestrated required an inspection of the binary with IDA. This revealed the start_flood and start_tick threads. The source code for the attack was found on Github. This code revealed a try_gb parameter, with the range of 0 to 1,024, used to configure how much data to input to flood the target. However, it was discovered that attackers are able to modify this open-source code to create a self-compiled binary that floods the host with even greater amounts of UDP packets. In the case of the Slowloris attack, cybercriminals launched DDoS with the slowhttptest utility. The attackers were able to create a self-compiling binary that is unidentifiable in malware scans. Protection from these Kubernetes attacks requires vigilant assurance policies and prevention of images other than compliant ones to run in the system. Non-compliant images will then be blocked when intrusion attempts are made. Man in the Middle Attacks With LoadBalancer or ExternalIPs An attack affecting all versions of Kubernetes involves multi-tenant clusters. The most vulnerable clusters have tenants that are able to create and update services and pods. In this breach, the attacker can intercept traffic from other pods or nodes in the cluster by creating a ClusterIP service and setting the spec.externalIP’s field. Additionally, a user who is able to patch the status of a LoadBalancer service can grab traffic. The only way to mitigate this threat is to restrict access to vulnerable features. This can be done with the admission webhook container, externalip-webhook , which prevents services from using random external IPs. An alternative method is to lock external IPs with OPA Gatekeeper with this sample Constraint Templatecan. Siloscape Malware Security researcher, Daniel Prizmant, describes a newer malware attack that he calls Siloscape. Its primary goal is to escape the container that is mainly implemented in Windows server silo. The malware targets Kubernetes through Windows containers to open a backdoor into poorly configured clusters to run the malicious containers. While other malware attacks focus on cryptojacking, the Siloscape user’s motive is to go undetected and open a backdoor to the cluster for a variety of malicious activities. This is possible since Siloscape is virtually undetectable due to a lack of readable strings in the binary. This type of attack can prove catastrophic. It compromises an entire cluster running multiple cloud applications. Cybercriminals can access critical information including sign-ins, confidential files, and complete databases hosted inside the cluster. Additionally, organizations using Kubernetes clusters for testing and development can face catastrophic damage should these environments be breached. To prevent a Siloscape attack, it is crucial that administrators ensure their Kubernetes clusters are securely configured. This will prevent the malware from creating new deployments and force Siloscape to exit. Microsoft also recommends using only Hyper-V containers as a security boundary for anything relying on containerization. The Threat Matrix The MITRE ATT&CK database details additional tactics and techniques attackers are using to infiltrate Kubernetes environments to access sensitive information, mine cryptocurrency, perform DDoS attacks, and other unscrupulous activities. The more commonly used methods are as follows: 1. Kubernetes file compromise Because this file holds sensitive data such as cluster credentials, an attacker could easily gain initial access to the entire cluster. Only accept kubeconfig files from trusted sources. Others should be thoroughly inspected before they are deployed. 2. Using similar pod names Attackers create similar pod names and use random suffixes to hide them in the cluster. The pods then run malicious code and obtain access to many other resources. 3. Kubernetes Secrets intrusion Attackers exploit any misconfigurations in the cluster with the goal of accessing the API server and retrieving information from the Secrets objects. 4. Internal network access Attackers able to access a single pod that communicates with other pods or applications can move freely within the cluster to achieve their goals. 5. Using the writeable hostPath mount Attackers with permissions to create new containers can create one with a writeable hostPath volume. Kubernetes Attacks: Key Takeaways Kubernetes brings many advantages to organizations but also presents a variety of security risks, as documented above. However, by ensuring their environments are adequately protected through proper configuration and appropriately assigned permissions, the threat of Kubernetes attacks is greatly minimized. Should a container be compromised, properly assigned privileges can severely limit a cluster-wide compromise.

Tags Share this article 7/22/21 Published Prof. Avishai Wool discusses the complexities of mergers and acquisitions for application management and how organizations can securely navigate the transition It comes as no surprise that the number of completed Mergers and Acquisitions (M&As) dropped significantly during the early stages of the pandemic as businesses closed ranks and focused on surviving rather than thriving. However, as we start to find some reprieve, many experts forecast that we’ll see an upturn in activity. In fact, by the end of 2020, M&A experienced a sudden surge and finished the year with only a 3% decline on 2019 levels. Acquiring companies is more than just writing a cheque. There are hundreds of things to consider both big and small, from infrastructure to staffing, which can make or break a merger. With that in mind, what do businesses need to do in order to ensure a secure and successful transition? When two worlds collide For many businesses, a merger or acquisition is highly charged. There’s often excitement about new beginnings mixed with trepidation about major business changes, not least when it comes to IT security. Mergers and acquisitions are like two planets colliding, each with their own intricate ecosystem. You have two enterprises running complex IT infrastructures with hundreds if not thousands of applications that don’t just simply integrate together. More often than not they perform replicated functions, which implies that some need to be used in parallel, while others need to be decommissioned and removed. This means amending, altering, and updating thousands of policies to accommodate new connections, applications, servers, and firewalls without creating IT security risks or outages. In essence, from an IT security perspective, a merger or acquisition is a highly complicated project that, if not planned and implemented properly, can have a long-term impact on business operations. Migrating and merging infrastructures One thing a business will need before it can even start the M&A process is an exhaustive inventory of all business applications spanning both businesses. An auto-discovery tool can assist here, collecting data from any application that is active on the network and adding it to a list. This should allow the main business to create a map of network connectivity flows which will form the cornerstone of the migration from an application perspective. Next comes security. A vulnerability assessment should be carried across both enterprise networks to identify any business-critical applications that may be put at risk. This assessment will give the main business the ability to effectively ‘rank’ applications and devices in terms of risk and necessity, allowing for priority lists to be created. This will help SecOps focus their efforts on crucial areas of the business that contain sensitive customer data, for instance. By following these steps you’ll get a clear organizational view of the entire enterprise environment and be able to identify and map all the critical business applications, linking vulnerabilities and cyber risks to specific applications and prioritize remediation actions based on business-driven needs. The power of automation While the steps outlined above will give you with an accurate picture of your IT topology and its business risk, this is only the first half of the story. Now you need to update security policies to support changes to business applications. Automation is critical when it comes to maintaining security during a merger or acquisition. An alarming number of data breaches are due to firewall misconfigurations, often resulting from attempts to change policies manually in a complex network environment. This danger increases with M&A, because the two merging enterprises likely have different firewall setups in place, often mixing traditional with next-generation firewalls or firewalls that come from different vendors. Automation is therefore essential to ensure the firewall change management process is handled effectively and securely with minimal risk of misconfigurations. Achieving true Zero-Touch automation in the network security domain is not an easy task but over time, you can let your automation solution run handsfree as you conduct more changes and gain trust through increasing automation levels step by step. Our Security Management Solution enables IT and security teams to manage and control all their security devices – from cloud controls in public clouds, SDNs, and on-premise firewalls from one single console. With AlgoSec you can automate time-consuming security policy changes and proactively assess risk to ensure continuous compliance. It is our business-driven approach to security policy management that enables organizations to reduce business risk, ensure security and continuous compliance, and drive business agility. Maintaining security throughout the transition A merger or acquisition presents a range of IT challenges but ensuring business applications can continue to run securely throughout the transition is critical. If you take an application centric approach and utilize automation, you will be in the best position for the merger/migration and will ultimately drive long term success.

Uncategorized Risk Management in Network Security: 7 Best Practices for 2024 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 1/26/24 Published Protecting an organization against every conceivable threat is rarely possible. There is a practically unlimited number of potential threats in the world, and security leaders don’t have unlimited resources available to address them. Prioritizing risks associated with more severe potential impact allows leaders to optimize cybersecurity decision-making and improve the organization’s security posture. Cybersecurity risk management is important because many security measures come with large costs. Before you can implement security controls designed to protect against cyberattacks and other potential risks, you must convince key stakeholders to support the project. Having a structured approach to cyber risk management lets you demonstrate exactly how your proposed changes impact the organization’s security risk profile. This makes it much easier to calculate the return on cybersecurity investment – making it a valuable tool when communicating with board members and executives. Here are seven tips every security leader should keep in mind when creating a risk management strategy: Cultivate a security-conscious risk management culture Use risk registers to describe potential risks in detail Prioritize proactive, low-cost risk remediation when possible Treat risk management as an ongoing process Invest in penetration testing to discover new vulnerabilities Demonstrate risk tolerance by implementing the NIST Cybersecurity Framework Don’t forget to consider false positives in your risk assessment What is a Risk Management Strategy? The first step to creating a comprehensive risk management plan is defining risk. According to the International Organization for Standardization (ISO) risk is “the effect of uncertainty on objectives”. This definition is accurate, but its scope is too wide. Uncertainty is everywhere, including things like market conditions, natural disasters, or even traffic jams. As a cybersecurity leader, your risk management process is more narrowly focused on managing risks to information systems, protecting sensitive data, and preventing unauthorized access. Your risk management program should focus on identifying these risks, assessing their potential impact, and creating detailed plans for addressing them. This might include deploying tools for detecting cyberattacks, implementing policies to prevent them, or investing in incident response and remediation tools to help you recover from them after they occur. In many cases, you’ll be doing all of these things at once. Crucially, the information you uncover in your cybersecurity risk assessment will help you prioritize these initiatives and decide how much to spend on them. Your risk management framework will provide you with the insight you need to address high-risk, high-impact cybersecurity threats first and manage low-risk, low-impact threats later on. 7 Tips for Creating a Comprehensive Risk Management Strategy 1. Cultivate a security-conscious risk management culture No CISO can mitigate security risks on their own. Every employee counts on their colleagues, partners, and supervisors to keep sensitive data secure and prevent data breaches. Creating a risk management strategy is just one part of the process of developing a security-conscious culture that informs risk-based decision-making. This is important because many employees have to make decisions that impact security on a daily basis. Not all of these decisions are critical-severity security scenarios, but even small choices can influence the way the entire organization handles risk. For example, most organizations list their employees on LinkedIn. This is not a security threat on its own, but it can contribute to security risks associated with phishing attacks and social engineering . Cybercriminals may create spoof emails inviting employees to fake webinars hosted by well-known employees, and use the malicious link to infect employee devices with malware. Cultivating a risk management culture won’t stop these threats from happening, but it might motivate employees to reach out when they suspect something is wrong. This gives security teams much greater visibility into potential risks as they occur, and increases the chance you’ll detect and mitigate threats before they launch active cyberattacks. 2. Use risk registers to describe potential risks in detail A risk register is a project management tool that describes risks that could disrupt a project during execution. Project managers typically create the register during the project planning phase and then refer to it throughout execution. A risk register typically uses the following characteristics to describe individual risks: Description : A brief overview of the risk itself. Category: The formal classification of the risk and what it affects. Likelihood: How likely this risk is to take place. Analysis: What would happen if this risk occurred. Mitigation: What would the team need to do to respond in this scenario. Priority: How critical is this risk compared to others. The same logic applies to business initiatives both large and small. Using a risk register can help you identify and control unexpected occurrences that may derail the organization’s ongoing projects. If these projects are actively supervised by a project manager, risk registers should already exist for them. However, there may be many initiatives, tasks, and projects that do not have risk registers. In these cases, you may need to create them yourself. Part of the overall risk assessment process should include finding and consolidating these risk registers to get an idea of the kinds of disruptions that can take place at every level of the organization. You may find patterns in the types of security risks that you find described in multiple risk registers. This information should help you evaluate the business impact of common risks and find ways to mitigate those risks effectively. 3. Prioritize proactive, low-cost risk remediation when possible Your organization can’t afford to prevent every single risk there is. That would require an unlimited budget and on-demand access to technical specialist expertise. However, you can prevent certain high-impact risks using proactive, low-cost policies that can make a significant difference in your overall security posture. You should take these opportunities when they present themselves. Password policies are a common example. Many organizations do not have sufficiently robust password policies in place. Cybercriminals know this –that’s why dictionary-based credential attacks still occur. If employees are reusing passwords across accounts or saving them onto their devices in plaintext, it’s only a matter of time before hackers notice. At the same time, upgrading a password policy is not an especially expensive task. Even deploying an enterprise-wide password manager and investing in additional training may be several orders of magnitude cheaper than implementing a new SIEM or similarly complex security platform. Your cybersecurity risk assessment will likely uncover many opportunities like this one. Take a close look at things like password policies, change management , and security patch update procedures and look for easy, low-cost projects that can provide immediate security benefits without breaking your budget. Once you address these issues, you will be in a much better position to pursue larger, more elaborate security implementations. 4. Treat risk management as an ongoing process Every year, cybercriminals leverage new tactics and techniques against their victims. Your organization’s security team must be ready to address the risks of emerging malware, AI-enhanced phishing messages, elaborate supply chain attacks, and more. As hackers improve their attack methodologies, your organization’s risk profile shifts. As the level of risk changes, your approach to information security must change as well. This means developing standards and controls that adjust according to your organization’s actual information security risk environment. Risk analysis should not be a one-time event, but a continuous one that delivers timely results about where your organization is today – and where it may be in the future. For example, many security teams treat firewall configuration and management as a one-time process. This leaves them vulnerable to emerging threats that they may not have known about during the initial deployment. Part of your risk management strategy should include verifying existing security solutions and protecting them from new and emerging risks. 5. Invest in penetration testing to discover new vulnerabilities There is more to discovering new risks than mapping your organization’s assets to known vulnerabilities and historical data breaches. You may be vulnerable to zero-day exploits and other weaknesses that won’t be immediately apparent. Penetration testing will help you discover and assess risks that you can’t find out about otherwise. Penetration testing mitigates risk by pinpointing vulnerabilities in your environment and showing how hackers could exploit them. Your penetration testing team will provide a comprehensive report showing you what assets were compromised and how. You can then use this information to close those security gaps and build a stronger security posture as a result. There are multiple kinds of penetration testing. Depending on your specific scenario and environment, you may invest in: External network penetration testing focuses on the defenses your organization deploys on internet-facing assets and equipment. The security of any business application exposed to the public may be assessed through this kind of test. Internal network penetration testing determines how cybercriminals may impact the organization after they gain access to your system and begin moving laterally through it. This also applies to malicious insiders and compromised credential attacks. Social engineering testing looks specifically at how employees respond to attackers impersonating customers, third-party vendors, and internal authority figures. This will help you identify risks associated with employee security training . Web application testing focuses on your organization’s web-hosted applications. This can provide deep insight into how secure your web applications are, and whether they can be leveraged to leak sensitive information. 6. Demonstrate risk tolerance by implementing the NIST Cybersecurity Framework The National Institute of Standards and Technology publishes one of the industry’s most important compliance frameworks for cybersecurity risk mitigation. Unlike similar frameworks like PCI DSS and GDPR, the NIST Cybersecurity Framework is voluntary – you are free to choose when and how you implement its controls in your organization. This set of security controls includes a comprehensive, flexible approach to risk management. It integrates risk management techniques across multiple disciplines and combines them into an effective set of standards any organization can follow. As of 2023, the NIST Risk Management Framework focuses on seven steps: Prepare the organization to change the way it secures its information technology solutions. Categorize each system and the type of information it processes according to a risk and impact analysis/ Select which NIST SP 800-53 controls offer the best data protection for the environment. Implement controls and document their deployment. Assess whether the correct controls are in place and operating as intended. Authorize the implementation in partnership with executives, stakeholders, and IT decision-makers. Monitor control implementations and IT systems to assess their effectiveness and discover emerging risks. 7. Don’t forget to consider false positives in your risk assessment False positives refer to vulnerabilities and activity alerts that have been incorrectly flagged. They can take many forms during the cybersecurity risk assessment process – from vulnerabilities that don’t apply to your organization’s actual tech stack to legitimate traffic getting blocked by firewalls. False positives can impact risk assessments in many ways. The most obvious problem they present is skewing your assessment results. This may lead to you prioritizing security controls against threats that aren’t there. If these controls are expensive or time-consuming to deploy, you may end up having an uncomfortable conversation with key stakeholders and decision-makers later on. However, false positives are also a source of security risks. This is especially true with automated systems like next-generation firewalls , extended detection and response (XDR) solutions, and Security Orchestration, Automation, and Response (SOAR) platforms. Imagine one of these systems detects an outgoing video call from your organization. It flags the connection as suspicious and begins investigating it. It discovers the call is being made from an unusual location and contains confidential data, so it blocks the call and terminates the connection. This could be a case of data exfiltration, or it could be the company CEO presenting a report to stockholders while traveling. Most risk assessments don’t explore the potential risk of blocking high-level executive communications or other legitimate communications due to false positives. Use AlgoSec to Identify and Assess Network Security Risks More Accurately Building a comprehensive risk management strategy is not an easy task. It involves carefully observing the way your organization does business and predicting how cybercriminals may exploit those processes. It demands familiarity with almost every task, process, and technology the organization uses, and the ability to simulate attack scenarios from multiple different angles. There is no need to accomplish these steps manually. Risk management platforms like AlgoSec’s Firewall Analyzer can help you map business applications throughout your network and explore attack simulations with detailed “what-if” scenarios. Use Firewall Analyzer to gain deep insight into how your organization would actually respond to security incidents and unpredictable events, then use those insights to generate a more complete risk management approach.

That’s what happened to the social media platform X in January 2023, when it was still Twitter. Hackers exploited an API vulnerability that had been exposed since June the previous year. This gave them access to the platform’s security system and allowed them to leak sensitive information on millions of users. This breach occurred because the organization’s firewalls were not configured to examine API traffic with enough scrutiny. This failure in firewall protection led to the leak of more than 200 million names, email addresses, and usernames, along with other information, putting victims at risk of identity theft . Firewalls are your organization’s first line of defense against malware and data breaches. They inspect all traffic traveling into and out of your network, looking for signs of cyber attacks and blocking malicious activity when they find it. This makes them an important part of every organization’s cybersecurity strategy. Effective firewall management and configuration is vital for preventing cybercrime. Read on to find out how you can protect your organization from attacks that exploit firewall vulnerabilities you may not be aware of. Understanding the 4 Types of Firewalls The first thing every executive and IT leader should know is that there are four basic types of firewalls . Each category offers a different level of protection, with simpler solutions costing less than more advanced ones. Most organizations need to use some combination of these four firewall types to protect sensitive data effectively. Keep in mind that buying more advanced firewalls is not always the answer. Optimal firewall management usually means deploying the right type of firewall for its particular use case. Ideally, these should be implemented alongside multi-layered network security solutions that include network detection and response, endpoint security, and security information and event management (SIEM) technology. 1. Packet Filtering Firewalls These are the oldest and most basic types of firewalls. They operate at the network layer, checking individual data packets for their source IP address and destination IP. They also verify the connection protocol, as well as the source port and destination port against predefined rules. The firewall drops packets that fail to meet these standards, protecting the network from potentially harmful threats. Packet filtering firewalls are among the fastest and cheapest types of firewalls available. Since they can not inspect the contents of data packets, they offer minimal functionality. They also can’t keep track of established connections or enforce rules that rely on knowledge of network connection states. This is why they are considered stateless firewalls. 2. Stateful Inspection Firewalls These firewalls also perform packet inspection, but they ingest more information about the traffic they inspect and compare that information against a list of established connections and network states. Stateful inspection firewalls work by creating a table that contains the IP and port data for traffic sources and destinations, and dynamically check whether data packets are part of a verified active connection. This approach allows stateful inspection firewalls to deny data packets that do not belong to a verified connection. However, the process of checking data packets against the state table consumes system resources and slows down traffic. This makes stateful inspection firewalls vulnerable to Distributed Denial-of-Service (DDoS) attacks. 3. Application Layer Gateways These firewalls operate at the application layer, inspecting and managing traffic based on specific applications or protocols, providing deep packet inspection and content filtering. They are also known as proxy firewalls because they can be implemented at the application layer through a proxy device. In practice, this means that an external client trying to access your system has to send a request to the proxy firewall first. The firewall verifies the authenticity of the request and forwards it to an internal server. They can also work the other way around, providing internal users with access to external resources (like public web pages) without exposing the identity or location of the internal device used. 4. Next-Generation Firewalls (NGFW) Next-generation firewalls combine traditional firewall functions with advanced features such as intrusion prevention, antivirus, and application awareness . They contextualize data packet flows and enrich them with additional data, providing comprehensive security against a wide range of threats. Instead of relying exclusively on IP addresses and port information, NGFWs can perform identity-based monitoring of individual users, applications, and assets. For example, a properly configured NGFW can follow a single user’s network traffic across multiple devices and operating systems, providing an activity timeline even if the user switches between a desktop computer running Microsoft Windows and an Amazon AWS instance controlling routers and iOT devices. How Do These Firewalls Function? Each type of firewall has a unique set of functions that serve to improve the organization’s security posture and prevent hackers from carrying out malicious cyber attacks. Optimizing your firewall fleet means deploying the right type of solution for each particular use case throughout your network. Some of the most valuable functions that firewalls perform include: Traffic Control They regulate incoming and outgoing traffic, ensuring that only legitimate and authorized data flows through the network. This is especially helpful in cases where large volumes of automated traffic can slow down routine operations and disrupt operations. For example, many modern firewalls include rules designed to deny bot traffic. Some non-human traffic is harmless, like the search engine crawlers that determine your website’s ranking against certain keyword searches. However, the vast majority of bot traffic is either unnecessary or malicious. Firewalls can help you keep your infrastructure costs down by filtering out connection attempts from automated sources you don’t trust. Protection Against Cyber Threats Firewalls act as a shield against various cyber threats, including phishing attacks, malware and ransomware attacks . Since they are your first line of defense, any malicious activity that targets your organization will have to bypass your firewall first. Hackers know this, which is why they spend a great deal of time and effort finding ways to bypass firewall protection. They can do this by exploiting technical vulnerabilities in your firewall devices or by hiding their activities in legitimate traffic. For example, many firewalls do not inspect authenticated connections from trusted users. If cybercriminals learn your login credentials and use your authenticated account to conduct an attack, your firewalls may not notice the malicious activity at all. Network Segmentation By defining access rules, firewalls can segment networks into zones with varying levels of trust, limiting lateral movement for attackers. This effectively isolates cybercriminals into the zone they originally infiltrated, and increases the chance they make a mistake and reveal themselves trying to access additional assets throughout your network. Network segmentation is an important aspect of the Zero Trust framework. Firewalls can help reinforce the Zero Trust approach by inspecting traffic traveling between internal networks and dropping connections that fail to authenticate themselves. Security Policy Enforcement Firewalls enforce security policies, ensuring that organizations comply with their security standards and regulatory requirements. Security frameworks like NIST , ISO 27001/27002 , and CIS specify policies and controls that organizations need to implement in order to achieve compliance. Many of these frameworks stipulate firewall controls and features that require organizations to invest in optimizing their deployments. They also include foundational and organizational controls where firewalls play a supporting role, contributing to a stronger multi-layered cybersecurity strategy. Intrusion Detection and Prevention Advanced firewalls include intrusion detection and prevention capabilities, which can identify and block suspicious activities in real-time. This allows security teams to automate their response to some of the high-volume security events that would otherwise drag down performance . Automatically detecting and blocking known exploits frees IT staff to spend more time on high-impact strategic work that can boost the organization’s security posture. Logging and Reporting Firewalls generate logs and reports that assist in security analysis, incident response, and compliance reporting. These logs provide in-depth data on who accessed the organization’s IT assets, and when the connection occurred. They enable security teams to conduct forensic investigations into security incidents, driving security performance and generating valuable insights into the organization’s real-world security risk profile. Organizations that want to implement SIEM technology must also connect their firewall devices to the platform and configure them to send log data to their SIEM for centralized analysis. This gives security teams visibility into the entire organization’s attack surface and enables them to adopt a Zero Trust approach to managing log traffic. Common Vulnerabilities & Weaknesses Firewalls Share Firewalls are crucial for network security, but they are not immune to vulnerabilities. Common weaknesses most firewall solutions share include: Zero-day vulnerabilities These are vulnerabilities in firewall software or hardware that are unknown to the vendor or the general public. Attackers can exploit them before patches or updates are available, making zero-day attacks highly effective. Highly advanced NGFW solutions can protect against zero-day attacks by inspecting behavioral data and using AI-enriched analysis to detect unknown threats. Backdoors Backdoors are secret entry points left by developers or attackers within a firewall’s code. These hidden access points can be exploited to bypass security measures. Security teams must continuously verify their firewall configurations to identify the signs of backdoor attacks. Robust and effective change management solutions help prevent backdoors from remaining hidden. Header manipulation Attackers may manipulate packet headers to trick firewalls into allowing unauthorized traffic or obscuring their malicious intent. There are multiple ways to manipulate the “Host” header in HTTP traffic to execute attacks. Security teams need to configure their firewalls and servers to validate incoming HTTP traffic and limit exposure to header vulnerabilities. How Cyber Criminals Exploit These Vulnerabilities Unauthorized Access Exploiting a vulnerability can allow cybercriminals to penetrate a network firewall, gaining access to sensitive data, proprietary information, or critical systems. Once hackers gain unauthorized access to a network asset, only a well-segmented network operating on Zero Trust principles can reliably force them to reveal themselves. Otherwise, they will probably remain hidden until they launch an active attack. Data Breaches Once inside your network, attackers may exfiltrate sensitive information, including customer data, intellectual property, and financial records (like credit cards), leading to data breaches. These complex security incidents can lead to major business disruptions and reputational damage, as well as enormous recovery costs. Malware Distribution Attackers may use compromised firewalls to distribute malware, ransomware, or malicious payloads to other devices within the network. This type of attack may focus on exploiting your systems and network assets, or it may target networks adjacent to your own – like your third-party vendors, affiliate partners, or customers. Denial of Service (DDoS) Exploited firewalls can be used in DDoS attacks, potentially disrupting network services and rendering them unavailable to users. This leads to expensive downtime and reputational damage. Some hackers try to extort their victims directly, demanding organizations pay money to stop the attack. 6 Techniques Used to Bypass Firewalls 1. Malware and Payload Delivery Attackers use malicious software and payloads to exploit firewall vulnerabilities, allowing them to infiltrate networks or systems undetected. This often occurs due to unpatched security vulnerabilities in popular firewall operating systems. For example, in June 2023 Fortinet addressed a critical-severity FortiOS vulnerability with a security patch. One month later in July, there were still 300,000 Fortinet firewalls still using the unpatched operating system. 2. Phishing Attacks Phishing involves tricking individuals into divulging sensitive information or executing malicious actions. Attackers use deceptive emails or websites that may bypass firewall filters. If they gain access to privileged user account credentials, they may be able to bypass firewall policies entirely, or even reconfigure firewalls themselves. 3. Social Engineering Tactics Cybercriminals manipulate human psychology to deceive individuals into disclosing confidential information, effectively bypassing technical security measures like firewalls. This is typically done through social media, email, or by telephone. Attackers may impersonate authority figures both inside and outside the organization and demand access to sensitive assets without going through the appropriate security checks. 4. Deep Packet Inspection Evasion Attackers employ techniques to disguise malicious traffic, making it appear benign to firewalls using deep packet inspection, allowing it to pass through undetected. Some open-source tools like SymTCP can achieve this by running symbolic executions on the server’s TCP implementation, scanning the resulting execution paths, and sending malicious data through any handling discrepancies identified. 5. VPNs and Remote Access Attackers may use Virtual Private Networks (VPNs) and remote access methods to circumvent firewall restrictions and gain unauthorized entry into networks. This is particularly easy in cases where simple geo restrictions block traffic from IP addresses associated with certain countries or regions. Attackers may also use more sophisticated versions of this technique to access exposed services that don’t require authentication, like certain containerized servers . 6. Intrusion Prevention Systems (IPS) Bypass Sophisticated attackers attempt to evade IPS systems by crafting traffic patterns or attacks that go undetected, enabling them to compromise network security. For example, they may use technologies to decode remote access tool executable files hidden inside certificate files, allowing them to reassemble the malicious file after it passes through the IPS. Protecting Against Firewall Vulnerabilities Multi-factor Authentication (MFA) MFA adds an extra layer of security by requiring users to provide multiple forms of identification, such as a password and a one-time code sent to their mobile device, before they gain access. This prevents attackers from accessing sensitive network assets immediately after stealing privileged login credentials. Knowing an account holder’s password and username is not enough. Two-factor Authentication (2FA) 2FA is a subset of MFA that involves using two authentication factors, typically something the user knows (password) and something the user has (a mobile device or security token), to verify identity and enhance firewall security. Other versions use biometrics like fingerprint scanning to authenticate the user. Intrusion Prevention Systems (IPS) IPS solutions work alongside firewalls to actively monitor network traffic for suspicious activity and known attack patterns, helping to block or mitigate threats before they can breach the network. These systems significantly reduce the amount of manual effort that goes into detecting and blocking known malicious attack techniques. Web Application Firewalls (WAF) WAFs are specialized firewalls designed to protect web applications from a wide range of threats, including SQL injection, cross-site scripting (XSS), and other web-based attacks. Since these firewalls focus specifically on HTTP traffic, they are a type of application level gateway designed specifically for web applications that interact with users on the public internet. Antivirus Software and Anti-malware Tools Deploying up-to-date antivirus and anti-malware software on endpoints, servers, and Wi-Fi network routers helps detect and remove malicious software, reducing the risk of firewall compromise. In order to work effectively, these tools must be configured to detect and mitigate the latest threats alongside the organization’s other security tools and firewalls. Automated solutions can help terminate unauthorized processes before attackers get a chance to deliver malicious payloads. Regular Updates and Patch Management Keeping firewalls and all associated software up-to-date with the latest security patches and firmware updates is essential for addressing known vulnerabilities and ensuring optimal security. Security teams should know when configuration changes are taking place, and be equipped to respond quickly when unauthorized changes take place. Implementing a comprehensive visibility and change management platform like AlgoSec makes this possible. With AlgoSec, you can simulate the effects of network configuration changes and proactively defend against sophisticated threats before attackers have a chance to strike. Monitoring Network Traffic for Anomalies Continuous monitoring of network traffic helps identify unusual patterns or behaviors that may indicate a security incident. Anomalies can trigger alerts for further investigation and response. Network detection and response solutions grant visibility into network activities that would otherwise go unnoticed, potentially giving security personnel early warning when unannounced changes or suspicious behaviors take place.

This includes ensuring access to corporate data is secured, connectivity to the data center from both internal and external users is secured, and that critical security updates are installed. Now comes the big question: what if you have to migrate your security policy to a new platform? With cloud computing and distributed data centers across the world nothing in technology is ever constant anymore. So how do you control and manage a firewall migration? What if you use multiple vendors’ solutions with both virtual and physical appliances? A firewall migration can be as simple as moving from one model to another, or a lot more complicated. As an experienced cloud architect, I’ve been a part of a number of firewall migration projects. Here are three tips to help make your firewall migration project a little bit easier. Create powerful firewall and security visibility map. All aspects of your firewall must be documented and well planned before doing a migration, and you must plan for both current as well as future needs. Start by gathering information: create a visual, dynamic map of your firewall architecture and traffic, which should include all technical connectivity data. Understand, document and prepare policy migration. Once you have your visual firewall map it’s time to look under the hood. One firewall might be easy, but is it ever really just one security appliance? The dynamic nature of the modern data center means that multiple security vendors can live under one roof. So how do you create a policy migration plan around heterogeneous platforms? You need to identify and document all the security policies and services and network algorithms for each firewall end-point. Analyze business impact and create a migration path. How do your applications interact with various security policies? Do you have specific business units relying on specific firewall traffic? How are various data centers being segmented by your security policies? Migrating a firewall will have a business-wide impact. You must ensure that this impact is absolutely minimal. You need to understand how your entire business model interacts with firewall and security technologies and if any piece of the business is forgotten technological headaches may be the least of your worries. Migrating a firewall doesn’t have to be hard, but it must be well planned. With so much information traversing the modern data center, it’s imperative to have complete visibility across the security architecture. Ultimately, with the right tools to help you plan, map and actually implement a firewall change process, and lots of cups of coffee, you can greatly reduce security migration complexity. #FirewallMigration Schedule a demo Related Articles 2025 in review: What innovations and milestones defined AlgoSec’s transformative year in 2025?
