Tags Share this article 2/11/24 Published Modern organizations face a wide and constantly changing range of network security threats, and security leaders must constantly update their security posture against them. As threat actors change their tactics, techniques, and procedures, exploit new vulnerabilities , and deploy new technologies to support their activities — it’s up to security teams to respond by equipping themselves with solutions that address the latest threats. The arms race between cybersecurity professionals and cybercriminals is ongoing. During the COVID-19 pandemic, high-profile ransomware attacks took the industry by storm. When enterprise security teams responded by implementing secure backup functionality and endpoint detection and response, cybercriminals shifted towards double extortion attacks. The cybercrime industry constantly invests in new capabilities to help hackers breach computer networks and gain access to sensitive data. Security professionals must familiarize themselves with the latest network security threats and deploy modern solutions that address them. What are the Biggest Network Security Threats? 1. Malware-based Cyberattacks Malware deserves a category of its own because so many high-profile attacks rely on malicious software to work. These include everything from the Colonial Pipeline Ransomware attack to historical events like Stuxnet . Broadly speaking, cyberattacks that rely on launching malicious software on computer systems are part of this category. There are many different types of malware-based cyberattacks, and they vary widely in scope and capability. Some examples include: Viruses. Malware that replicates itself by inserting its own code into other applications are called viruses. They can spread across devices and networks very quickly. Ransomware. This type of malware focuses on finding and encrypting critical data on the victim’s network and then demanding payment for the decryption key. Cybercriminals typically demand payment in the form of cryptocurrency, and have developed a sophisticated industrial ecosystem for conducting ransomware attacks. Spyware. This category includes malware variants designed to gather information on victims and send it to a third party without your consent. Sometimes cybercriminals do this as part of a more elaborate cyberattack. Other times it’s part of a corporate espionage plan. Some spyware variants collect sensitive information that cybercriminals value highly. Trojans. These are malicious applications disguised as legitimate applications. Hackers may hide malicious code inside legitimate software in order to trick users into becoming victims of the attack. Trojans are commonly hidden as an email attachment or free-to-download file that launches its malicious payload after being opened in the victim’s environment. Fileless Malware. This type of malware leverages legitimate tools native to the IT environment to launch an attack. This technique is also called “living off the land” because hackers can exploit applications and operating systems from inside, without having to download additional payloads and get them past firewalls. 2. Network-Based Attacks These are attacks that try to impact network assets or functionality, often through technical exploitations. Network-based attacks typically start at the edge of the network, where it sends and receives traffic to the public internet. Distributed Denial-of-Service (DDoS) Attacks. These attacks overwhelm network resources, leading to downtime and service unavailability, and in some cases, data loss . To launch DDoS attacks, cybercriminals must gain control over a large number of compromised devices and turn them into bots. Once thousands (or millions) of bots using unique IP addresses request server resources, the server breaks down and stops functioning. Man-in-the-Middle (MitM) Attacks: These attacks let cybercriminals eavesdrop on communications between two parties. In some cases, they can also alter the communications between both parties, allowing them to plan and execute more complex attacks. Many different types of man-in-the-middle attacks exist, including IP spoofing, DNS spoofing, SSL stripping, and others. 3. Social Engineering and Phishing These attacks are not necessarily technical exploits. They focus more on abusing the trust that human beings have in one another. Usually, they involve the attacker impersonating someone in order to convince the victim to give up sensitive data or grant access to a secure asset. Phishing Attacks. This is when hackers create fake messages telling victims to take some kind of action beneficial to the attacker. These deceptive messages can result in the theft of login credentials, credit card information, or more. Most major institutions are regularly impersonated by hackers running phishing scams, like the IRS . Social Engineering Attacks. These attacks use psychological manipulation to trick victims into divulging confidential information. A common example might be a hacker contacting a company posing as a third-party technology vendor, asking for access to a secure system, or impersonating the company CEO and demanding an employee pay a fictitious invoice. 4. Insider Threats and Unauthorized Access These network security threats are particularly dangerous because they are very difficult to catch. Most traditional security tools are not configured to detect malicious insiders, who generally have permission to access sensitive data and assets. Insider Threats. Employees, associates, and partners with access to sensitive data may represent severe security risks. If an authorized user decides to steal data and sell it to a hacker or competitor, you may not be able to detect their attack using traditional security tools. That’s what makes insider threats so dangerous, because they are often undetectable. Unauthorized Access. This includes a broad range of methods used to gain illegal access to networks or systems. The goal is usually to steal data or alter it in some way. Attackers may use credential-stuffing attacks to access sensitive networks, or they can try brute force methods that involve automatically testing millions of username and password combinations until they get the right one. This often works because people reuse passwords that are easy to remember. Solutions to Network Security Threats Each of the security threats listed above comes with a unique set of risks, and impacts organizations in a unique way. There is no one-size-fits-all solution to navigating these risks. Every organization has to develop a cybersecurity policy that meets its specific needs. However, the most secure organizations usually share the following characteristics. Fundamental Security Measures Well-configured Firewalls. Firewalls control incoming and outgoing network traffic based on security rules. These rules can deny unauthorized traffic attempting to connect with sensitive network assets and block sensitive information from traveling outside the network. In each case, robust configuration is key to making the most of your firewall deployment . Choosing a firewall security solution like AlgoSec can dramatically improve your defenses against complex network threats. Anti-malware and Antivirus Software. These solutions detect and remove malicious software throughout the network. They run continuously, adapting their automated scans to include the latest threat detection signatures so they can block malicious activity before it leads to business disruption. Since these tools typically rely on threat signatures, they cannot catch zero-day attacks that leverage unknown vulnerabilities. Advanced Protection Tools Intrusion Prevention Systems. These security tools monitor network traffic for behavior that suggests unauthorized activity. When they find evidence of cyberattacks and security breaches, they launch automated responses that block malicious activity and remove unauthorized users from the network. Network Segmentation. This is the process of dividing networks into smaller segments to control access and reduce the attack surface. Highly segmented networks are harder to compromise because hackers have to repeatedly pass authentication checks to move from one network zone to another. This increases the chance that they fail, or generate activity unusual enough to trigger an alert. Security and Information Event Management (SIEM) platforms. These solutions give security analysts complete visibility into network and application activity across the IT environment. They capture and analyze log data from firewalls, endpoint devices, and other assets and correlate them together so that security teams can quickly detect and respond to unauthorized activity, especially insider threats. Endpoint Detection and Response (EDR). These solutions provide real-time visibility into the activities of endpoint devices like laptops, desktops, and mobile phones. They monitor these devices for threat indicators and automatically respond to identified threats before they can reach the rest of the network. More advanced Extended Detection and Response (XDR) solutions draw additional context and data from third party security tools and provide in-depth automation . Authentication and Access Control Multi-Factor Authentication (MFA). This technology enhances security by requiring users to submit multiple forms of verification before accessing sensitive data. This makes it useful against phishing attacks, social engineering, and insider threats, because hackers need more than just a password to gain entry to secure networks. MFA also plays an important role in Zero Trust architecture. Strong Passwords and Access Policies. There is no replacement for strong password policies and securely controlling user access to sensitive data. Security teams should pay close attention to password policy compliance, making sure employees do not reuse passwords across accounts and avoid simple memory hacks like adding sequential numbers to existing passwords. Preventing Social Engineering and Phishing While SIEM platforms, MFA policies and strong passwords go a long way towards preventing social engineering and phishing attacks, there are a few additional security measures worth taking to reduce these risks: Security Awareness Training. Leverage a corporate training LMS to educate employees about phishing and social engineering tactics. Phishing simulation exercises can help teach employees how to distinguish phishing messages from legitimate ones, and pinpoint the users at highest risk of falling for a phishing scam. Email Filtering and Verification: Email security tools can identify and block phishing emails before they arrive in the inbox. They often rely on scanning the reputation of servers that send incoming emails, and can detect discrepancies in email metadata that suggest malicious intent. Even if these solutions generally can’t keep 100% of malicious emails out of the inbox, they significantly reduce email-related threat risks. Dealing with DDoS and MitM Attacks These technical exploits can lead to significant business disruption, especially when undertaken by large-scale threat actors with access to significant resources. Your firewall configuration and VPN policies will make the biggest difference here: DDoS Prevention Systems. Protect against distributed denial of service attacks by implementing third-party DDoS prevention solutions, deploying advanced firewall configurations, and using load balancers. Some next generation firewalls (NGFWs) can increase protection against DDoS attacks by acting as a handshake proxy and dropping connection requests that do not complete the TCP handshake process. VPNs and Encryption: VPNs provide secure communication channels that prevent MitM attacks and data eavesdropping. Encrypted traffic can only be intercepted by attackers who go through the extra step of obtaining the appropriate decryption key. This makes it much less likely they focus on your organization instead of less secure ones that are easier to target. Addressing Insider Threats Insider threats are a complex security issue that require deep, multi-layered solutions to address. This is especially true when malicious insiders are actually employees with legitimate user credentials and privileges. Behavioral Auditing and Monitoring: Regular assessments and monitoring of user activities and network traffic are vital for detecting insider threats . Security teams need to look beyond traditional security deployments and gain insight into user behaviors in order to catch authorized users doing suspicious things like escalating their privileges or accessing sensitive data they do not normally access. Zero Trust Security Model. Assume no user or device is trustworthy until verified. Multiple layers of verification between highly segmented networks — with multi-factor authentication steps at each layer — can make it much harder for insider threats to steal data and conduct cyberattacks. Implementing a Robust Security Strategy Directly addressing known threats should be just one part of your cybersecurity strategy. To fully protect your network and assets from unknown risks, you must also implement a strong security posture that can address risks associated with new and emerging cyber threats. Continual Assessment and Improvement The security threat landscape is constantly changing, and your security posture must adapt and change in response. It’s not always easy to determine exactly how your security posture should change, which is why forward-thinking security leaders periodically invest in vulnerability assessments designed to identify security vulnerabilities that may have been overlooked. Once you have a list of security weaknesses you need to address, you can begin the process of proactively addressing them by configuring your security tech stack and developing new incident response playbooks. These playbooks will help you establish a coordinated, standardized response to security incidents and data breaches before they occur. Integration of Security Tools Coordinating incident response plans isn’t easy when every tool in your tech stack has its own user interface and access control permissions. You may need to integrate your security tools into a single platform that allows security teams to address issues across your entire network from a single point of reference. This will help you isolate and address security issues on IoT devices and mobile devices without having to dedicate a particular team member exclusively to that responsibility. If a cyberattack that targets mobile apps occurs, your incident response plan won’t be limited by the bottleneck of having a single person with sufficient access to address it. Similarly, highly integrated security tools that leverage machine learning and automation can enhance the scalability of incident response and speed up incident response processes significantly. Certain incident response playbooks can be automated entirely, providing near-real-time protection against sophisticated threats and freeing your team to focus on higher-impact strategic initiatives. Developing and Enforcing Security Policies Developing and enforcing security policies is one of the high-impact strategic tasks your security team should dedicate a great deal of time and effort towards. Since the cybersecurity threat landscape is constantly changing, you must commit to adapting your policies in response to new and emerging threats quickly. That means developing a security policy framework that covers all aspects of network and data security. Similarly, you can pursue compliance with regulatory standards that ensure predictable outcomes from security incidents. Achieving compliance with standards like NIST, CMMC, PCI-DSS, and HIPPA can help you earn customers’ trust and open up new business opportunities.

Cloud Security Best Practices for Docker Containers’ Security 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 7/27/20 Published Containers aren’t VMs. They’re a great lightweight deployment solution, but they’re only as secure as you make them. You need to keep them in processes with limited capabilities, granting them only what they need. A process that has unlimited power, or one that can escalate its way there, can do unlimited damage if it’s compromised. Sound security practices will reduce the consequences of security incidents. Don’t grant absolute power It may seem too obvious to say, but never run a container as root. If your application must have quasi-root privileges, you can place the account within a user namespace , making it the root for the container but not the host machine. Also, don’t use the –privileged flag unless there’s a compelling reason. It’s one thing if the container does direct I/O on an embedded system, but normal application software should never need it. Containers should run under an owner that has access to its own resources but not to other accounts. If a third-party image requires the –privileged flag without an obvious reason, there’s a good chance it’s badly designed if not malicious. Avoid running a Docker socket in a container. It gives the process access to the Docker daemon, which is a useful but dangerous power. It includes the ability to control other containers, images, and volumes. If this kind of capability is necessary, it’s better to go through a proper API. Grant privileges as needed Applying the principle of least privilege minimizes container risks. A good approach is to drop all capabilities using –cap-drop=all and then enabling the ones that are needed with –cap-add . Each capability expands the attack surface between the container and its environment. Many workloads don’t need any added capabilities at all. The no-new-privileges flag under security-opt is another way to protect against privilege escalation. Dropping all capabilities does the same thing, so you don’t need both. Limiting the system resources which a container guards not only against runaway processes but against container-based DoS attacks. Beware of dubious images When possible, use official Docker images. They’re well documented and tested for security issues, and images are available for many common situations. Be wary of backdoored images . Someone put 17 malicious container images on Docker Hub, and they were downloaded over 5 million times before being removed. Some of them engaged in cryptomining on their hosts, wasting many processor cycles while generating $90,000 in Monero for the images’ creator. Other images may leak confidential data to an outside server. Many containerized environments are undoubtedly still running them. You should treat Docker images with the same caution you’d treat code libraries, CMS plugins, and other supporting software, Use only code that comes from a trustworthy source and is delivered through a reputable channel. Other considerations It should go without saying, but you need to rebuild your images regularly. The libraries and dependencies that they use get security patches from time to time, and you need to make sure your containers have them applied. On Linux, you can gain additional protection from security profiles such as secomp and AppArmor . These modules, used with the security-opt settings, let you set policies that will be automatically enforced. Container security presents its distinctive challenges. Experience with traditional application security helps in many ways, but Docker requires an additional set of practices. Still, the basics apply as much as ever. Start with trusted code. Don’t give it the power to do more than it needs to do. Use the available OS and Docker features for enhancing security. Monitor your systems for anomalous behavior. If you take all these steps, you’ll ward off the large majority of threats to your Docker environment.

Firewall Change Management To NAT or not to NAT – It’s not really a question 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 11/26/13 Published NAT Network Security I came across some discussions regarding Network Address Translation (NAT) and its impact on security and the network. Specifically the premise that “ NAT does not add any real security to a network while it breaks almost any good concepts of a structured network design ” is what I’d like to address. When it comes to security, yes, NAT is a very poor protection mechanism and can be circumvented in many ways. It causes headaches to network administrators. So now that we’ve quickly summarized all that’s bad about NAT, let’s address the realization that most organizations use NAT because they HAVE to, not because it’s so wonderful. The alternative to using NAT has a prohibitive cost and is possibly impossible. To dig into what I mean, let’s walk through the following scenario… Imagine you have N devices in your network that need an IP address (every computer, printer, tablet, smartphone, IP phone, etc. that belongs to your organization and its guests). Without NAT you would have to purchase N routable IP addresses from your ISP. The costs would skyrocket! At AlgoSec we run a 120+ employee company in numerous countries around the globe. We probably use 1000 IP addresses. We pay for maybe 3 routable IP addresses and NAT away the rest. Without NAT the operational cost of our IP infrastructure would go up by a factor of x300. NAT Security With regards to NAT’s impact on security, just because NAT is no replacement for a proper firewall doesn’t mean it’s useless. Locking your front door also provides very low-grade security – people still do it, since it’s a lot better than not locking your front door.

A data breach can be devastating, leading to financial losses, legal headaches, and irreparable damage to your reputation. Cloud encryption is your key to protecting your valuable data and ensuring peace of mind in the cloud. In this article, we'll explore cloud encryption and how AlgoSec can help you implement it effectively. We'll cover the basics of encryption, its benefits, the challenges you might face, and best practices to ensure your data stays safe. What Is Cloud Encryption? Cloud encryption is like creating a secret code for your data. It scrambles your information so that only authorized people with the key can read it. This process ensures that even if someone gains unauthorized access to your data, they won't be able to understand or use it. Cloud encryption is essential for protecting sensitive information like customer data, financial records, and intellectual property. It helps organizations meet compliance requirements, maintain data privacy, and safeguard their reputation. Encryption in Action: Protecting Data at Rest and in Transit Cloud encryption can be used to protect data in two states: Data at Rest: This refers to data that is stored in the cloud, such as in databases or storage buckets. Encryption ensures that even if someone gains access to the storage, they can't read the data without the encryption key. Data in Transit: This refers to data that is moving between locations, such as between your computer and a cloud server. Encryption protects the data while it travels over the internet, preventing eavesdropping and unauthorized access. How does it work? Cloud encryption uses algorithms to transform your data into an unreadable format. Think of it like this: Symmetric encryption: You and the recipient have the same key to lock (encrypt) and unlock (decrypt) the data. It's like using the same key for your front and back door. Asymmetric encryption: There are two keys: a public key to lock the data and a private key to unlock it. It's like having a mailbox with a slot for anyone to drop mail in (public key), but only you have the key to open the mailbox (private key). Why Encrypt Your Cloud Data? Cloud encryption offers a wide range of benefits: Compliance: Avoid costly fines and legal battles by meeting compliance requirements like GDPR, HIPAA, and PCI DSS. Data Protection: Safeguard your sensitive data, whether it's financial transactions, customer information, or intellectual property. Control and Ownership: Maintain control over your data and who can access it. Insider Threat Protection: Reduce the risk of data breaches caused by malicious or negligent employees. Multi-Tenancy Security: Enhance data security and isolation in shared cloud environments. Cloud Encryption Challenges (and How AlgoSec Helps) While cloud encryption is essential, it can be complex to manage. Here are some common challenges: Key Management: Securely managing encryption keys is crucial. Losing or mismanaging keys can lead to data loss. AlgoSec Solution: AlgoSec provides a centralized key management system to simplify and secure your encryption keys. Compliance: Meeting various regional and industry-specific regulations can be challenging. AlgoSec Solution: AlgoSec helps you navigate compliance requirements and implement appropriate encryption controls. Shared Responsibility: Understanding the shared responsibility model and your role in managing encryption can be complex. AlgoSec Solution: AlgoSec provides clear guidance and tools to help you fulfill your security responsibilities. Cloud Encryption Best Practices Encrypt Everything: Encrypt data both at rest and in transit. Choose Strong Algorithms: Use strong encryption algorithms like AES-256. Manage Keys Securely: Use a key management system (KMS) like the one provided by AlgoSec to automate and secure key management. Control Access: Implement strong access controls and identity management systems. Stay Compliant: Adhere to industry standards and regulations. Monitor and Audit: Regularly monitor your encryption implementation and conduct audits to ensure ongoing effectiveness. Conclusion Protecting your data in the cloud is non-negotiable. Cloud encryption is a fundamental security measure that every organization should implement. By understanding the benefits, challenges, and best practices of cloud encryption, you can make informed decisions to safeguard your sensitive information.

Tags Share this article 8/9/23 Published Firewall misconfigurations are one of the most common and preventable security issues that organizations face. Comprehensively managing access control, addressing vulnerabilities, and detecting configuration mistakes under these conditions is not easy It’s especially challenging for organizations that use the default firewall rules provided by their vendor. Your firewall policies should reflect your organization’s unique cybersecurity risk profile. This requires some degree of customization, and intelligence into kinds of cyber attacks hackers use to target your organization. Understanding security misconfigurations and their impact on network security Security misconfigurations happen when elements of your security tech stack expose preventable vulnerabilities that hackers can exploit. These misconfigurations can take a variety of forms, putting a wide range of security tools and open ports at risk. Network firewall misconfigurations can have a wide-ranging impact on your organization’s overall security posture. Hackers that target vulnerable infrastructure pose a threat to the entire application stack. They may be able to gain access to network services, application servers, and virtual machines. Depending on the specific misconfiguration, they may be able to compromise hardware routers and endpoints as well. In organizations with complex firewall deployments, attackers may be able to exploit misconfigurations, bypass security policies, and escalate their own privileges to make arbitrary changes to firewall security. From this point, attackers can easily modify access control lists (ACLs) to specifically allow the malware they wish to run, compromising the first line of defense against data breaches. This is exactly why Gartner recommends implementing a centralized solution for firewall management . Centralized visibility and control is crucial for maintaining effective firewall configurations and updating them accordingly. Otherwise, ensuring compliance with security best practices like the principle of least privilege becomes difficult or impossible. Routing network traffic through complex cloud-native infrastructure securely requires deep visibility into firewall configuration status, effective authentication processes, and automation-friendly security solutions. How hackers exploit misconfigured firewalls Common misconfigurations include implementing overly permissive rules, disabling critical security features, and neglecting to protect open ports against unauthorized access. This leaves organizations vulnerable to Distributed Denial-of-Service (DDoS) attacks, remote control, and data breaches . Here are some of the ways cybercriminals can exploit misconfigured firewalls: 1. Taking advantage of permissions misconfigurations Overly permissive firewall rules are a common problem among organizations with complex cloud-enabled infrastructure. Often, the organization’s demand for productivity and connectivity take precedence over the need to protect sensitive data from unauthorized network traffic. Additionally, IT team members may misunderstand the cloud provider’s shared responsibility model and assume that the provider has already secured the data center from all potential threats. These situations are particularly risky when the organization is undergoing change. For example, many security professionals start with completely open permissions and tighten them as they learn more about the network’s needs. Obvious and highly visible permissions get secured first, while less visible parts of the security framework are deprioritized – or never addressed at all. Hackers can exploit this situation by focusing on less obvious access points first. Instead of sending malicious traffic to IP addresses associated with core business servers, they might infiltrate the network through an unsecured API, or look for an unpatched operating system somewhere in the network. 2. Exploiting disabled security features Many firewalls offer advanced security features to organizations willing to configure them. However, security teams are often strained for time and resources. They may already be flooded with a backlog of high-priority security alerts to address, making it challenging to spend extra time configuring advanced firewall policies or fine-tuning their security posture. Even organizations that can enable advanced features don’t always do it. Features like leak detection and port scan alerts can put additional strain on limited computing resources, impacting performance. Other features may generate false positives, which only add to the security workload. But many of these features offer clear benefits to organizations that use them. Sophisticated technologies like application and identity-based inspection allow organizations to prioritize firewall performance more efficiently throughout the network. If threat actors find out that advanced security features like these are disabled, they are free to deploy the attack techniques these features protect against. For example, in the case of identity-based inspection, a hacker may be able to impersonate an unidentified administrator-level account and gain access to sensitive security controls without additional authentication. 3. Scanning for unsecured open ports Hackers use specialized penetration testing tools to scan for open ports. Tools like Nmap, Unicornscan , and Angry IP Scanner can find open ports and determine the security controls that apply to them. If a hacker finds out that your ACLs neglect to cover a particular port, they will immediately look for ways to exploit that vulnerability and gain access to your network. These tools are the same network discovery tools that system administrators and network engineers use on a routine basis. Tools like Nmap allow IT professionals to run security audits on local and remote networks, identifying hosts responding to network requests, discovering operating system names and versions, and more. Threat actors can even determine what kind of apps are running and find the version number of those apps. They also allow threat actors to collect data on weak points in your organization’s security defenses. For example, they might identify a healthcare organization using an outdated app to store sensitive clinical trial data. From there, it’s easy to look up the latest patch data to find out what exploits the outdated app is vulnerable to. How to optimize firewall configuration Protecting your organization from firewall breaches demands paying close attention to the policies, patch versions, and additional features your firewall provider offers. Here are three steps security leaders can take to address misconfiguration risks and ensure a robust security posture against external threats: 1. Audit your firewall policies regularly This is especially important for organizations undergoing the transition to cloud-native infrastructure. It’s virtually guaranteed that certain rules and permissions will no longer be needed as the organization adjusts to this period of change over time. Make sure that your firewall rules are constantly updated to address these changes and adapt to them accordingly. Auditing should take place under a strict change management framework . Implement a change log and incorporate it into your firewall auditing workflow so that you can easily access information about historical configuration changes. This change log will provide security professionals with readymade data about who implemented configuration changes, what time those changes took place, and why they were made in the first place. This gives you at-a-glance coverage of historical firewall performance, which puts you one step closer to building a unified, centralized solution for handling firewall policies. 2. Update and patch firewall software frequently Like every element in your security tech stack, firewall software needs to be updated promptly when developers release new patches. This applies both to hardware firewalls operating on-premises and software firewalls working throughout your network. These patches address known vulnerabilities, and they are often the first line of defense against rapidly emerging threats. The sooner you can deploy software patches to your firewalls, the more robust your network security posture will be. These changes should also be noted in a change log. This provides valuable evidence for the strength of your security posture against known emerging threats. If hackers start testing your defenses by abusing known post-patch vulnerabilities, you will be prepared for them. 3. Implement an intrusion detection system (IDS) Firewalls form the foundation of good network security, and intrusion detection systems supplement their capabilities by providing an additional line of defense. Organizations with robust IDS capabilities are much harder to compromise without triggering alerts. IDS solutions passively monitor traffic for signs of potential threats. When they detect a threat, they generate an alert, allowing security operations personnel to investigate and respond. This adds additional layers of value to the basic function of the firewall – allowing or denying traffic based on ACLs and network security rules. Many next-generation firewalls include intrusion detection system capabilities as part of an integrated solutions. This simplifies security management considerably and reduces the number of different devices and technologies security teams must gain familiarity with. Pay attention to firewall limitations – and prepare for them Properly configured firewalls offer valuable security performance to organizations with complex network infrastructure. However, they can’t prevent every cyber attack and block every bit of malicious code. Security leaders should be aware of firewall limitations and deploy security measures that compensate appropriately. Even with properly configured firewalls, you’ll have to address some of the following issues: Zero-day attacks Firewalls may not block attacks that exploit new and undiscovered vulnerabilities. Since these are not previously known vulnerabilities, security teams have not yet had time to develop patches or fixes that address them. These types of attacks are generally able to bypass more firewall solutions. However, some next-generation firewalls do offer advanced features capable of addressing zero-day attacks. Identity-based inspection is one example of a firewall technology that can detect these attacks because it enforces security policies based on user identity rather than IP address. Sandboxes are another next-generation firewall technology capable of blocking zero-day attacks. However, no single technology can reliably block 100% of all zero-day attacks. Some solutions are better-equipped to handle these types of attacks than others, but it takes a robust multi-layered security posture to consistently protect against unknown threats. Timely incident response Firewall configuration plays an important role in incident response. Properly configured firewalls help provide visibility into your security posture in real-time, enabling security teams to create high-performance incident response playbooks. Custom playbooks ensure timely incident response by prioritizing the types of threats found in real-world firewall data. If your firewalls are misconfigured, your incident response playbooks may reflect a risk profile that doesn’t match with your real-world security posture. This can lead to security complications that reduce the effectiveness of incident response processes down the line. Planned outages when updating firewalls Updating firewalls is an important part of maintaining an optimal firewall configuration for your organization. However, the update process can be lengthy. At the same time, it usually requires scheduling an outage in advance, which will temporarily expose your organization to the threats your firewall normally protects against. In some cases, there may be compatibility issues with incoming version of the firewall software being updated. This may lengthen the amount of time that the organization has to endure a service outage, which complicates firewall security. This is one reason why many security leaders intentionally delay updating their firewalls. As with many other aspects of running and maintaining good security policies, effective change management is an important aspect of planning firewall updates. Security leaders should stagger their scheduled updates to avoid reducing risk exposure and provide the organization with meaningful security controls during the update process.

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 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?

Auditing and Compliance Compliance Made Easy: How to improve your risk posture with automated audits Tal Dayan 2 min read Tal Dayan 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 4/29/21 Published Tal Dayan, security expert for AlgoSec, discusses the secret to passing audits seamlessly and how to introduce automated compliance Compliance standards come in many different shapes and sizes. Some organizations set their own internal policies, while others are subject to regimented global frameworks such as PCI DSS , which protects customers’ card payment details; SOX to safeguard financial information or HIPAA , which protects patients’ healthcare data. Regardless of which industry you operate in, regular auditing is key to ensuring your business retains its risk posture whilst also remaining compliant. The problem is that running manual risk and security audits can be a long, drawn-out, and tedious affair. A 2020 report from Coalfire and Omdia  found that for the majority of organizations, growing compliance obligations are now consuming 40% or more of IT security budgets and threaten to become an unsustainable cost.  The report suggests two reasons for this growing compliance burden.  First, compliance standards are changing from point-in-time reviews to continuous, outcome-based requirements. Second, the ongoing cyber-skills shortage is stretching organizations’ abilities to keep up with compliance requirements. This means businesses tend to leave them until the last moment, leading to a rushed audit that isn’t as thorough as it could be, putting your business at increased risk of a penalty fine or, worse, a data breach that could jeopardize the entire organization. The auditing process itself consists of a set of requirements that must be created for organizations to measure themselves against. Each rule must be manually analyzed and simulated before it can be implemented and used in the real world. As if that wasn’t time-consuming enough, every single edit to a rule must also be logged meticulously. That is why automation plays a key role in the auditing process. By striking the right balance between automated and manual processes, your business can achieve continuous compliance and produce audit reports seamlessly. Here is a six-step strategy that can set your business on the path to sustainable and successful ongoing auditing preservation: Step 1: Gather information This step will be the most arduous but once completed it will become much easier to sustain. This is when you’ll need to gather things like security policies, firewall access logs, documents from previous audits and firewall vendor information – effectively everything you’d normally factor into a manual security audit. Step 2: Define a clear change management process A good change management process is essential to ensure traceability and accountability when it comes to firewall changes. This process should confirm that every change is properly authorized and logged as and when it occurs, providing a picture of historical changes and approvals. Step 3: Audit physical & OS security With the pandemic causing a surge in the number of remote workers and devices used, businesses must take extra care to certify that every endpoint is secured and up-to-date with relevant security patches. Crucially, firewall and management services should also be physically protected, with only designated personnel permitted to access them. Step 4: Clean up & organize rule base As with every process, the tidier it is, the more efficient it is. Document rules and naming conventions should be enforced to ensure the rule base is as organized as possible, with identical rules consolidated to keep things concise. Step 5: Assess & remediate risk Now it’s time to assess each rule and identify those that are particularly risky and prioritize them by severity. Are there any that violate corporate security policies? Do some have “ANY” and a permissive action? Make a list of these rules and analyze them to prepare plans for remediation and compliance. Step 6: Continuity & optimization Now it’s time to simply hone the first five steps and make these processes as regular and streamlined as possible. By following the above steps and building out your own process, you can make day-to-day compliance and auditing much more manageable. Not only will you improve your compliance score, you’ll also be able to maintain a sustainable level of compliance without the usual disruption and hard labor caused by cumbersome and expensive manual processes.

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?

Firewall traffic analysis (FTA) is a network security operation that grants visibility into the data packets that travel through your network’s firewalls. Cybersecurity professionals conduct firewall traffic analysis as part of wider network traffic analysis (NTA) workflows. The traffic monitoring data they gain provides deep visibility into how attacks can penetrate your network and what kind of damage threat actors can do once they succeed. NTA vs. FTA Explained NTA tools provide visibility into things like internal traffic inside the data center, inbound VPN traffic from external users, and bandwidth metrics from Internet of Things (iOT) endpoints. They inspect on-premises devices like routers and switches, usually through a unified, vendor-agnostic interface. Network traffic analyzers do inspect firewalls, but might stop short of firewall-specific network monitoring and management. FTA tools focus more exclusively on traffic patterns through the organization’s firewalls. They provide detailed information on how firewall rules interact with traffic from different sources. This kind of tool might tell you how a specific Cisco firewall conducts deep packet inspection on a certain IP address, and provide broader metrics on how your firewalls operate overall. It may also provide change management tools designed to help you optimize firewall rules and security policies . Firewall Rules Overview Your firewalls can only protect against security threats effectively when they are equipped with an optimized set of rules. These rules determine which users are allowed to access network assets and what kind of network activity is allowed. They play a major role in enforcing network segmentation and enabling efficient network management. Analyzing device policies for an enterprise network is a complex and time-consuming task. Minor mistakes can lead to critical risks remaining undetected and expose network devices to cyberattacks. For this reason, many security leaders use automated risk management solutions that include firewall traffic analysis. These tools perform a comprehensive analysis of firewall rules and communicate the risks of specific rules across every device on the network. This information is important because it will inform the choices you make during real-time traffic analysis. Having a comprehensive view of your security risk profile allows you to make meaningful changes to your security posture as you analyze firewall traffic. Performing Real-Time Traffic Analysis AlgoSec Horizon Security Analyzer captures information on the following traffic types: External IP addresses Internal IP addresses (public and private, including NAT addresses) Protocols (like TCP/IP, SMTP, HTTP, and others) Port numbers and applications for sources and destinations Incoming and outgoing traffic Potential intrusions The platform also supports real-time network traffic analysis and monitoring. When activated, it will periodically inspect network devices for changes to their policy rules, object definitions, audit logs, and more. You can view the changes detected for individual devices and groups, and filter the results to find specific network activities according to different parameters. For any detected change, Horizon Security Analyzer immediately aggregates the following data points: Device – The device where the changes happened. Date/Time – The exact time when the change was made. Changed by – Tells you which administrator performed the change. Summary – Lists the network assets impacted by the change. Many devices supported by Horizon Security Analyzer are actually systems of devices that work together. You can visualize the relationships between these assets using the device tree format. This presents every device as a node in the tree, giving you an easy way to manage and view data for individual nodes, parents nodes, and global categories. For example, Horizon Security Analyzer might discover a redundant rule copied across every firewall in your network. If its analysis shows that the rule triggers frequently, it might recommend moving to a higher node on the device tree. If it turns out the rule never triggers, it may recommend adjusting the rule or deleting it completely. If the rule doesn’t trigger because it conflicts with another firewall rule, it’s clear that some action is needed. Importance of Visualization and Reporting Open source network analysis tools typically work through a command-line interface or a very simple graphic user interface. Most of the data you can collect through these tools must be processed separately before being communicated to non-technical stakeholders. High-performance firewall analysis tools like AlgoSec Horizon Security Analyzer provide additional support for custom visualizations and reports directly through the platform. Visualization allows non-technical stakeholders to immediately grasp the importance of optimizing firewall policies, conducting netflow analysis, and improving the organization’s security posture against emerging threats. For security leaders reporting to board members and external stakeholders, this can dramatically transform the success of security initiatives. AlgoSec Horizon Security Analyzer includes a Visualize tab that allows users to create custom data visualizations. You can save these visualizations individually or combine them into a dashboard. Some of the data sources you can use to create visualizations include: Interactive searches Saved searches Other saved visualizations Traffic Analysis Metrics and Reports Custom visualizations enhance reports by enabling non-technical audiences to understand complex network traffic metrics without the need for additional interpretation. Metrics like speed, bandwidth usage, packet loss, and latency provide in-depth information about the reliability and security of the network. Analyzing these metrics allows network administrators to proactively address performance bottlenecks, network issues, and security misconfigurations. This helps the organization’s leaders understand the network’s capabilities and identify the areas that need improvement. For example, an organization that is planning to migrate to the cloud must know whether its current network infrastructure can support that migration. The only way to guarantee this is by carefully measuring network performance and proactively mitigating security risks. Network traffic analysis tools should do more than measure simple metrics like latency. They need to combine latency into complex performance indicators that show how much latency is occuring, and how network conditions impact those metrics. That might include measuring the variation in delay between individual data packets (jitter), Packet Delay Variation (PDV), and others. With the right automated firewall analysis tool, these metrics can help you identify and address security vulnerabilities as well. For example, you could automate the platform to trigger alerts when certain metrics fall outside safe operating parameters. Exploring AlgoSec’s Network Traffic Analysis Tool AlgoSec Horizon Security Analyzer provides a wide range of operations and optimizations to security teams operating in complex environments. It enables firewall performance improvements and produces custom reports with rich visualizations demonstrating the value of its optimizations. Some of the operations that Horizon Security Analyzer supports include: Device analysis and change tracking reports. Gain in-depth data on device policies, traffic, rules, and objects. It analyzes the routing table that produces a connectivity diagram illustrating changes from previous reports on every device covered. Traffic and routing queries. Run traffic simulations on specific devices and groups to find out how firewall rules interact in specific scenarios. Troubleshoot issues that emerge and use the data collected to prevent disruptions to real-world traffic. This allows for seamless server IP migration and security validation. Compliance verification and reporting. Explore the policy and change history of individual devices, groups, and global categories. Generate custom reports that meet the requirements of corporate regulatory standards like Sarbanes-Oxley, HIPAA, PCI DSS, and others. Rule cleanup and auditing. Identify firewall rules that are either unused, timed out, disabled, or redundant. Safely remove rules that fail to improve your security posture, improving the efficiency of your firewall devices. List unused rules, rules that don’t conform to company policy, and more. Horizon Security Analyzer can even re-order rules automatically, increasing device performance while retaining policy logic. User notifications and alerts. Discover when unexpected changes are made and find out how those changes were made. Monitor devices for rule changes and send emails to pre-assigned users with device analyses and reports. Network Traffic Analysis for Threat Detection and Response By monitoring and inspecting network traffic patterns, firewall analysis tools can help security teams quickly detect and respond to threats. Layer on additional technologies like Intrusion Detection Systems (IDS), Network Detection and Response (NDR), and Threat Intelligence feeds to transform network analysis into a proactive detection and response solution. IDS solutions can examine packet headers, usage statistics, and protocol data flows to find out when suspicious activity is taking place. Network sensors may monitor traffic that passes through specific routers or switches, or host-based intrusion detection systems may monitor traffic from within a host on the network. NDR solutions use a combination of analytical techniques to identify security threats without relying on known attack signatures. They continuously monitor and analyze network traffic data to establish a baseline of normal network activity. NDR tools alert security teams when new activity deviates too far from the baseline. Threat intelligence feeds provide live insight on the indicators associated with emerging threats. This allows security teams to associate observed network activities with known threats as they develop in real-time. The best threat intelligence feeds filter out the huge volume of superfluous threat data that doesn’t pertain to the organization in question. Firewall Traffic Analysis in Specific Environments On-Premises vs. Cloud-hosted Environments Firewall traffic analyzers exist in both on-premises and cloud-based forms. As more organizations migrate business-critical processes to the cloud, having a truly cloud-native network analysis tool is increasingly important. The best of these tools allow security teams to measure the performance of both on-premises and cloud-hosted network devices, gathering information from physical devices, software platforms, and the infrastructure that connects them. Securing the Internet of Things It’s also important that firewall traffic analysis tools take Internet of Things (IoT) devices in consideration. These should be grouped separately from other network assets and furnished with firewall rules that strictly segment them. Ideally, if threat actors compromise one or more IoT devices, network segmentation won’t allow the attack to spread to other parts of the network. Conducting firewall analysis and continuously auditing firewall rules ensures that the barriers between network segments remain viable even if peripheral assets (like IoT devices) are compromised. Microsoft Windows Environments Organizations that rely on extensive Microsoft Windows deployments need to augment the built-in security capabilities that Windows provides. On its own, Windows does not offer the kind of in-depth security or visibility that organizations need. Firewall traffic analysis can play a major role helping IT decision-makers deploy technologies that improve the security of their Windows-based systems. Troubleshooting and Forensic Analysis Firewall analysis can provide detailed information into the causes of network problems, enabling IT professionals to respond to network issues more quickly. There are a few ways network administrators can do this: Analyzing firewall logs. Log data provides a wealth of information on who connects to network assets. These logs can help network administrators identify performance bottlenecks and security vulnerabilities that would otherwise go unnoticed. Investigating cyberattacks. When threat actors successfully breach network assets, they can leave behind valuable data. Firewall analysis can help pinpoint the vulnerabilities they exploited, providing security teams with the data they need to prevent future attacks. Conducting forensic analysis on known threats. Network traffic analysis can help security teams track down ransomware and malware attacks. An organization can only commit resources to closing its security gaps after a security professional maps out the killchain used by threat actors to compromise network assets. Key Integrations Firewall analysis tools provide maximum value when integrated with other security tools into a coherent, unified platform. Security information and event management (SIEM) tools allow you to orchestrate network traffic analysis automations with machine learning-enabled workflows to enable near-instant detection and response. Deploying SIEM capabilities in this context allows you to correlate data from different sources and draw logs from devices across every corner of the organization – including its firewalls. By integrating this data into a unified, centrally managed system, security professionals can gain real-time information on security threats as they emerge. AlgoSec’s Horizon Security Analyzer integrates seamlessly with leading SIEM solutions, allowing security teams to monitor, share, and update firewall configurations while enriching security event data with insights gleaned from firewall logs. Horizon Security Analyzer uses a REST API to transmit and receive data from SIEM platforms, allowing organizations to program automation into their firewall workflows and manage their deployments from their SIEM.
