Tags Share this article 11/27/20 Published With the rapid proliferation of cloud computing, lean deployment methods, such as containers, have become common practice. According to CIO.com, 70% of global companies are expected to be running multiple apps simultaneously using a containerized framework, like Kubernetes in the next few years. But as Kubernetes’ use becomes more widespread, so do the vulnerabilities inherent to containerization. According to a 2019 Forbes article , Kubernetes had at least 7,000 identified vulnerabilities at the beginning of 2019 alone. Couple that with the fact that cyber-attacks involving containerization have increased a whopping 240% since 2018, and you’ll understand the value of security should your company use a solution like Kubernetes to handle its container orchestration. What Causes Kubernetes Security Blindspots? To understand how to best optimize your Kubernetes experience, it’s worthwhile to understand the basic ways security issues arise in a containerized framework. Images are the core building blocks of containerization; they are the executable process at the centre of your container. As a result, anything that exposes an image to a broader audience puts the container at risk of being hijacked. One of the primary ways this occurs is by using out-of-date software. Using old software gives malicious actors a small incongruence that they can exploit within the code. Another problem is poorly defined user access roles. If sensible changes aren’t made to an orchestration tool’s default settings, inappropriate parties may have access to alter the container’s core executable. Containerization gives you a way to manage a large number of processes easily and with increased adaptability. As a result, automation makes it impossible to keep your eyes on everything at once. Here are some best practices that can help you counter the wide range of vulnerabilities inherent to containerization and Kubernetes in general. Kubernetes Security Best Practices Given the architecture of the Kubernetes framework, security risks are a constant and evolving threat. Luckily, Google made Kubernetes an open-source application under the auspices of the Cloud Native Computing Foundation where solutions to new security issues are actively crowdsourced by the community. Regardless, there are a number of things that you can do during the build, deployment, and runtime phases to make your Kubernetes implementation more secure. Take care of your images Images are the heart of every container. Executable functions are essential, so images must be well-maintained and in good working order. Only use up-to-date images, scanning them regularly for security issues. As a rule of thumb, you should also avoid including unnecessary tools and functions in your image coding as they can inadvertently give hackers an access route. Ensure that your secrets remain secret The term “secrets” refers to any private information such as login credentials, tokens, or other sensitive data. While it’s not customary to keep sensitive data stored adjacent to the container’s image, the scenario has come up before. Keep secret data as far from the image as possible in order to increase security. Keep up-to-date with scans and security patches The community does a good job of patching Kubernetes when issues arise. If you don’t take the time to update both your OS and Kubernetes’ security, you give malware additional avenues of attack. Updates should be performed at least every nine months, if not more often. Due to the nature of how Kubernetes works, if you are using an outdated version, you could actively be spreading issues when the container is deployed elsewhere. Take advantage of customization to define user roles and access A container orchestration tool like Kubernetes is a complex web running thousands of processes across numerous machines. That means hundreds of end-users involved with the application. Take advantage of Kubernetes administrative functions to clearly define user roles, limiting full access for those who don’t need it. As they say, too many cooks spoil the broth. Keeping Kubernetes Simple and Safe Containers are an agile, lightweight framework for cloud computing, but manually deploying the correct containers to their destinations can quickly become overwhelming. An orchestration tool like Kubernetes is the perfect solution to managing your containerization, but the security risks inherent to this model can be restrictive. By keeping a few key practices in mind when implementing Kubernetes into your workflow, you can help to promote safety while streamlining your processes. To Sum It All Up Kubernetes has become the centrepiece of the cloud Native landscape and a notable advantage for organizations to rapidly manage and deploy their containerized business logic. But certain security best practices must be followed such as working with reliable docker images, properly defined resource quotas, network policies, work with namespaces for access control and authentication\authorization, and more.

    One of the market’s most comprehensive annual vendor-agnostic studies found that rapid cloud expansion, distributed workloads, and AI-driven traffic patterns are driving increased demand for unified policy control and end-to-end transparency AlgoSec’s 2026 State of Network Security Report Reveals Rising Demand for Consolidation and Control One of the market’s most comprehensive annual vendor-agnostic studies found that rapid cloud expansion, distributed workloads, and AI-driven traffic patterns are driving increased demand for unified policy control and end-to-end transparency February 4, 2026 Speak to one of our experts RIDGEFIELD PARK, NJ, February 4, 2026 – Global cybersecurity leader AlgoSec has released its annual State of Network Security Report, providing a comprehensive vendor-agnostic analysis of today’s network security landscape. The report identifies a decisive shift in how organizations are responding to network evolution and hybrid architecture sprawl, with the focus shifting back towards consolidation; defined by unification, automation and control as businesses look to manage visibility of risk and resilience posture. Based on comparative year-on-year findings, AlgoSec’s research includes over 500 responses from security, network and cloud professionals across 28 countries and evaluates market leaders including AWS, Cisco, Microsoft Azure, GCP, Check Point, Palo Alto Networks, Fortinet and more. Key findings from the report include: AI-powered threats and defences go mainstream – Artificial intelligence has become both the newest threat vector and the next frontier of defence. For the first time, AlgoSec’s research asked how organizations are adjusting to the rise of AI-powered attacks. The majority (65%) have already adapted their strategies, with 23.6% making major structural changes and 40.9% implementing moderate adjustments. Cloud firewall strategies prioritize consolidation - The move toward cloud-based firewalls continues, but with a change in tone. Nearly a quarter (24%) of respondents plan to move primarily to cloud firewalls over the next two years, confirming that cloud-native controls are no longer a consideration, but a baseline expectation. Security becomes the deciding factor in cloud platform selection – The rise of AI-driven workloads, compliance requirements and cross-platform orchestration has made security the critical benchmark for platform selection, with 54.7% of organizations stating that security capabilities carry the most weight when selecting a cloud platform. SD-WAN further cements its role – As organizations expand their hybrid environments and distributed workforces, the demand for secure, high-performance connectivity has solidified SD-WAN’s role. Fortinet (31%) has become the most widely used SD-WAN solution while Cisco (30.7%) remains a close second. SASE moves from exploration to standardization – For the third year running, the share of organizations without a SASE solution has declined, down to 27.5% from 40% in 2024. This consistent decrease signals that SASE adoption is no longer exploratory, but a planned progression for most enterprises. “Compared to last year, we are now seeing a transition from experimentation to optimization,” said Eran Shiff, Chief Product Officer at AlgoSec. “After several years of rapid expansion across multi-cloud environments, AI-powered operations and hybrid architectures, organizations are entering a new phase of consolidation and control.

  • Firewall audit checklist for security policy rules review | AlgoSec

    Ensure your network security is up to par with a comprehensive firewall audit checklist. Review and optimize security policy rules to prevent vulnerabilities. Firewall audit checklist for security policy rules review Ensuring continuous compliance More regulations and standards relating to information security, such as the Payment Card Industry Data Security Standard (PCI-DSS), the General Data Protection Regulation (GDPR), Sarbanes-Oxley (SOX), Health Insurance Portability and Accountability Act (HIPAA), California Consumer Privacy Act (CCPA) and ISO 27001, have forced enterprises to put more emphasis—in terms of time and money—on compliance and the regular and ad hoc auditing of security policies and controls. While regulatory and internal audits cover a broad range of security checks, the firewall is featured prominently since it is the first and main line of defense between the public and the corporate network. The number of enterprises that are not affected by regulations is shrinking. But even if you do not have to comply with specific government or industrial regulations and security standards, it is now commonplace to conduct regular, thorough audits of your firewalls. Not only do these audits ensure that your firewall configurations and rules meet the proper requirements of external regulations or internal security policy, but these audits can also play a critical role in reducing risk and actually improve firewall performance by optimizing the firewall rule base. In today’s complex, multi-vendor network environments, typically including tens or hundreds of firewalls running thousands of rules, completed a manual security audit now borders on the impossible. Conducting the audit process manually, firewall administrators must rely on their own experience and expertise—which can vary greatly across organizations—to determine if a given firewall rule should or should not be included in the configuration file. Furthermore, documentation of current rules and their evolution of changes is usually lacking. The time and resources required to find, organize and pour through all of the firewall rules to determine the level of compliance significantly impacts IT staff. As networks grow in complexity, auditing becomes more cumbersome. Manual processes cannot keep up. Automating the firewall audit process is crucial as compliance must be continuous, not simply at a point in time. The firewall audit process is arduous. Each new rule must pre-analyzed and simulated before it can be implemented. A full and accurate audit log of each change must be maintained. Today’s security staffs now find that being audit-ready without automation is impractical if not virtually impossible. It’s time to look to automation along with the establishment of auditing best practices to maintain continuous compliance. Below, we share a proven checklist of six best practices for a firewall audits based on AlgoSec’s extensive experience in consulting with some of the largest global organizations and auditors who deal with firewall audit, optimization and change management processes and procedures. While this is not an exhaustive list that every organization must follow, it provides guidance on some critical areas to cover when conducting a firewall audit. FIGURE 1: Overview of the Recommended Firewall Audit Process Get a Demo Schedule a Demo Gather key information prior to starting the audit An audit has little chance of success without visibility into the network, including software, hardware, policies and risks. The following are examples of the key information required to plan the audit work: Copies of relevant security policies Access to firewall logs that can be analyzed against the firewall rule base to understand which rules are actually being used An accurate diagram of the current network and firewall topologies Reports and documents from previous audits, including firewall rules, objects and policy revisions Identification of all Internet Service Providers (ISP) and Virtual Private Networks (VPN) All relevant firewall vendor information including OS version, latest patches and default configuration Understanding all the key servers and information repositories in the network and the value of each Once you have gathered this information, how are you going to aggregate it and storing it? Trying to track compliance on spreadsheets is a surefire way to make the audit process painful, tedious and time-consuming. Instead of spreadsheets, the auditor needs to document, store and consolidate this vital information in a way that enables collaboration with IT counterparts. With this convenience access, auditors you can start reviewing policies and procedures and tracking their effectiveness in terms of compliance, operational efficiency and risk mitigation. Schedule a Demo Review the change management process A good change management process is essential to ensure proper execution and traceability of firewall changes as well as for sustainability over time to ensure compliance continuously. Poor documentation of changes, including why each change is needed, who authorized the change, etc. and poor validation of the impact on the network of each change are two of the most common problems when it comes to change control. Review the procedures for rule-base change management. Just a few key questions to review include:Are requested changes going through proper approvals? Are changes being implemented by authorized personnel? Are changes being tested? Are changes being documented per regulatory and/ or internal policy requirements? Each rule should have a comment that includes the change ID of the request and the name/initials of the person who implemented the change. Is there an expiration date for the change? Determine if there is a formal and controlled process in place to request, review, approve and implement firewall changes. This process should include at least the following:Business purpose for a change request Duration (time period) for new/modified rule Assessment of the potential risks associated with the new/modified rule Formal approvals for new/modified rule Assignment to proper administrator for implementation Verification that change has been tested and implemented correctly Determine whether all of the changes have been authorized and flag unauthorized rule changes for further investigation. Determine if real-time monitoring of changes to a firewall are enabled and if access to rul Schedule a Demo Audit the firewall’s physical and OS security It is important to be certain as to each firewall’s physical and software security to protect against the most fundamental types of cyberattack. Ensure that firewall and management servers are physically secured with controlled access. Ensure that there is a current list of authorized personnel permitted to access the firewall server rooms. Verify that all appropriate vendor patches and updates have been applied. Ensure that the operating system passes common hardening checklists. Review the procedures used for device administration. Schedule a Demo Cleanup and optimize the rule base Removing firewall clutter and optimizing the rule base can greatly improve IT productivity and firewall performance. Additionally, optimizing firewall rules can significantly reduce a lot of unnecessary overhead in the audit process. Delete covered rules that are effectively useless. Delete or disable expired and unused rules and objects. Identify disabled, time-inactive and unused rules that are candidates for removal. Evaluate the order of firewall rules for effectiveness and performance. Remove unused connections, including source/ destination/service routes, that are not in use. Detect similar rules that can be consolidated into a single rule. Identify overly permissive rules by analyzing the actual policy usage against firewall logs. Tune these rules as appropriate for policy and actual use scenarios. Analyze VPN parameters to identify unused users, unattached users, expired users, users about to expire, unused groups, unattached groups and expired groups. Enforce object-naming conventions. Document rules, objects and policy revisions for future reference. Schedule a Demo Conduct a risk assessment and remediate issues Essential for any firewall audit, a comprehensive risk assessment will identify risky rules and ensure that rules are compliant with internal policies and relevant standards and regulations. Identify any and all potentially “risky” rules, based on industry standards and best practices, and prioritize them by severity. What is “risky” can be different for each organization depending on the network and the level of acceptable risk, but there are many frameworks and standards you can leverage that provide a good reference point. A few things to look for and validate include: Are there firewall rules that violate your corporate security policy? Are there any firewall rules with “ANY” in the source, destination, service/protocol, application or user fields, and with a permissive action? Are there rules that allow risky services from your DMZ to your internal network? Are there rules that allow risky services inbound from the Internet? Are there rules that allow risky services outbound to the Internet? Are there rules that allow direct traffic from the Internet to the internal network (not the DMZ)? Are there any rules that allow traffic from the Internet to sensitive servers, networks, devices or databases? Analyze firewall rules and configurations against relevant regulatory and/or industry standards such as PCI-DSS, SOX, ISO 27001, NERC CIP, Basel-II, FISMA and J-SOX, as well as corporate policies that define baseline hardware and software configurations to which devices must adhere (See Figure 4 on page 9). Document and assign an action plan for remediation of risks and compliance exceptions found in risk analysis. Verify that remediation efforts and any rule changes have been completed correctly. Track and document that remediation efforts are completed. Schedule a Demo Ongoing audits Upon successful firewall and security device auditing, verifying secure configuration, proper steps must be put in place to ensure continuous compliance. Ensure that a process is established for continuous auditing of firewalls. Consider replacing error-prone manual tasks with automated analysis and reporting. Ensure that all audit procedures are properly documented, providing a complete audit trail of all firewall management activities. Make sure that a robust firewall-change workflow is in place to sustain compliance over time.This repeats Audit Checklist item #2 because is necessary to ensure continuous compliance, i.e., compliance might be achieved now, but in a month, the organization might once again be out of compliance. Ensure that there is an alerting system in place for significant events or activities, such as changes in certain rules or the discovery of a new, high severity risk in the policy. Schedule a Demo Automating firewall compliance audits with AlgoSec When it comes to compliance, the firewall policy management solution must have the breadth and depth to automatically generate detailed reports for multiple regulations and standards. It also must support multiple firewalls and related security devices. By combining this firewall audit checklist with the AlgoSec Security Management Solution, organizations can significantly improve their security posture and reduce the pain of ensuring compliance with regulations, industry standards and corporate policies. Furthermore, they can ensure compliance continuously without spending significant resources wasting time and effort on complex security policies on a regular basis. Let’s go back through the checklist and look at a few examples of how AlgoSec can help. Gain visibility of network policies and their changes AlgoSec enables you to gather the key information needed to start the audit process. By generating a dynamic, interactive network map AlgoSec visualizes and helps you analyze complex networks. (See Figure 2.) You can view routing tables and effectively detect interfaces, subnets and zones. Additionally, AlgoSec provides you with visibility of all changes to your network security policies in real-time and creates detailed firewall audit reports to help approvers make informed decisions about changes that affect risk or compliance levels. Lastly, AlgoSec discovers all the business applications that run on your network and each of their associated connectivity flows. FIGURE 2: AlgoSec provides network topology awareness with a map that provides visibility of all firewalls and routers including all relevant interfaces, subnets and zones, and the ability to drill down to specific information about each device. Understand the firewall changes in your network and automate the process AlgoSec intelligently automates the security-policy change workflow, dramatically cutting the time required to process firewall changes, increasing accuracy and accountability, enforcing compliance and mitigating risk. In addition, AlgoSec provides flexible workflows and templates to help you manage change requests and tailor processes to your business needs. Clean up and optimize your rule base AlgoSec enables you to optimize and clean up cluttered policies with actionable recommendations to: Consolidate similar rules. Discover and remove unused rules and objects (See Figure 3). Identify and remove shadowed, duplicate, and expired rules. Reorder rules for optimal firewall performance while retaining policy logic. Tighten overly permissive rules based on actual usage patterns. Not only does this help you improve the performance and extend the life of your firewalls, it also saves time when it comes to troubleshooting issues and IT audits. Plus, it creates a time savings during rule recertification, as each application is associated with multiple connectivity needs requiring multiple firewall rules. FIGURE 3: Unused rules that AlgoSec has identified for removal. Conduct a risk assessment and remediate issues AlgoSec enables you to instantly discover and prioritize all risks and potentially risky rules in the firewall policy, leveraging the largest risk knowledgebase available. The knowledgebase includes industry regulations, best practices and customizable corporate security policies. AlgoSec assigns and tracks a security rating for each device and group of devices to help you to quickly pinpoint devices that require attention and to measure the effectiveness of a security policy over time. FIGURE 4: AlgoSec identifies and prioritizes risky rules based on industry standards and frameworks and provides detailed information of source, destination, service, as well as user and application when analyzing next-generation firewalls. Out-of-the-box compliance reports AlgoSec ensures continuous compliance and instantly provides you with a view of your firewall compliance status by automatically generating reports for industry regulations, including Payment Card Industry Data Security Standard (PCI DSS), GDPR, Sarbanes-Oxley (SOX), Financial Instruments and Exchange Act (J-SOX, also known as Japan-SOX), North American Electric Reliability Corporation Critical Infrastructure Protection (NERC CIP), and International Organization for Standardization (ISO 20071). If the network security policy doesn’t adhere to regulatory or corporate standards, the reports identify the exact rules and devices that cause gaps in compliance. A single report provides visibility into risk and compliance associated with a group of devices. FIGURE 5: PCI DSS firewall compliance report automatically generated by AlgoSec. Schedule a Demo Conclusion Ensuring and proving compliance typically require significant organizational resources and budget. With the growing litany of regulations, the cost and time involved in the audit process is increasing rapidly.

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.
