Learn best practices for effective network firewall security management. Enhance your security posture with proper configuration, monitoring, and maintenance. Network firewall security management What are network firewalls? Network firewalls are the first round of defense against a wide range of external threats. Firewall policies filter incoming traffic to protect the network ecosystem from cyberattacks. Network traffic that doesn’t meet filter criteria gets blocked. Security teams continually optimize their organization’s firewall configuration to address new and emerging threats. Schedule a Demo Network firewall security challenges Network infrastructure is more complex than ever before. In the early days, your network firewall sat at the perimeter of your data center. Today, you may have a variety of firewalls operating on-premises, in public and private clouds, in a software-defined network, or a multi-cloud hybrid environment. Security leaders face four main challenges when implementing, maintaining and improving firewall performance: Complexity – The more individual firewall solutions your network relies on, the harder it is to analyze, configure, and scale firewall-related workflows. Visibility – The traffic flows over your network are complex. Lack of visibility over traffic flows makes managing firewall policies more difficult. Automation – Network firewalls have hundreds of security policies. Spread over multiple devices, manual management is difficult and time-consuming. Automation of network security management is the solution. Compliance – Proper configuration of your network security devices is a common regulatory requirement. Make sure you can demonstrate compliance. 1. Managing firewall configuration in a complex environment Since early networks were mostly on-premises, managing firewall configuration changes in real-time was simple. Once the cybersecurity team identified firewall changes they wanted to make, a single employee could upload those changes to the organization’s Cisco PIX device and call it a day. Today’s networks simply don’t work that way. They are designed to be scalable, supporting a wide range of endpoint devices and cloud-based applications with a much wider attack surface than ever before. Security teams must protect their networks against a more sophisticated set of attacks, including malware that leverages zero-day vulnerabilities and other unknown threats. At the same time, they must accommodate both users and attackers equipped with modern security tools like VPNs. The modern organization must deploy a wide range of firewalls, including hardware devices physically connected to local routers, software firewalls for hybrid cloud environments, and next-generation firewalls equipped with analyzers that can proactively detect unknown threats. Security leaders need to streamline visibility into firewall configuration, orchestration, and management through a single pane of glass. This ensures optimal firewall performance for both on-premises and cloud security solutions, while freeing team members to spend more time on higher impact strategic security goals. 2. Firewall deployments can compromise visibility into security processes Modern organizations with complex network configurations often don’t enjoy deep visibility into their security processes and event outcomes. Many third-party managed security vendors don’t offer in-depth data about their processes at all. Security leaders are often asked to simply trust that vendors provide enough value to justify premium pricing. But losing visibility into security processes makes it extremely challenging to improve those processes. It puts security leaders in the uncomfortable position of defending security outcomes they don’t have adequate data to explain. In the event of a negative outcome, it’s almost impossible to explain exactly what went wrong and why. If a particular firewall policy is ultimately responsible for that outcome, security leaders need to know. Effective firewall security management isn’t possible without deep visibility into firewall policies, and how those rules impact day-to-day business operations in real-time. Obtaining this kind of visibility in a complex network environment is not easy, but it’s vital to long-term success. 3. Manual configuration changes are costly and error-prone Increasing configuration errors are another knock-on consequence of the trend towards bigger and more complex networks. Where early network security professionals only had to update firewall rules for a handful of devices, now they must accommodate an entire stack of solutions made by different manufacturers, with complicated interdependencies between them. Most organizations rely on multiple providers for their full firewall stack. They may use Cisco hardware, Checkpoint next-generation firewalls, Tufin firewall management software, and Firemon asset management all at the same time. Managing and troubleshooting this kind of deployment without comprehensive firewall security management software is difficult and time-consuming. Security misconfigurations as a whole are responsible for more than one-third of all cyberattacks. This demonstrates the urgent need for security leaders to automate the process of configuring, updating, and validating firewall changes on complex networks. AlgoSec provides security leaders with a robust set of tools for automating network security policy updates and firewall changes without requiring organizations to dedicate additional employee-hours to time-consuming manual processes. 4. Don’t forget to document policy changes for compliance Security policy management is an important part of overall security compliance. Adhering to the latest security standards published by reputable organizations allows security leaders to meaningfully reduce cybersecurity risk. Documents like the NIST Cybersecurity Framework provide clear guidance into how organizations should address core functions in their security strategy, which includes deploying and updating firewalls. In particular, NIST Special Publication 800-41 describes the guidelines for firewall policies, requiring that they be based on comprehensive risk assessment for the organization in question. The guidelines also require that organizations with multiple firewalls sharing the same rules (or common subsets of rules) must have those rules synchronized across those firewalls. Importantly, all these changes must be documented. This requirement adds significant risk and complexity to network environments that rely on manual configuration processes. Even if you successfully implement changes the right way, reporting discrepancies can negatively impact your organization’s regulatory position. AlgoSec generates compliance reports for NIST SP 800-53 as a built-in feature, available right out of the box. Organizations that use AlgoSec to automate firewall security management and policy changes can ensure compliance with stringent security standards without having to commit valuable security resources to manually verifying reports. Schedule a Demo Firewall security management FAQs Understanding the network security devices in your network is crucial to maintaining your network’s security. What are some common network security devices? Network security devices include application and network firewalls, which are the most popular network security devices. However, your network may have other devices such as intrusion detection and protection systems, antivirus scanning devices, content filtering devices, as well as pen testing devices, and vulnerability assessment appliances. What is an application firewall? An application firewall controls access from an application or service, monitoring or blocking the system service calls that do not meet the firewall’s configured policy. The application firewall is typically built to control network traffic up to the application layer. What is a firewall device and how do firewalls work? A firewall is a network security device that monitors network traffic and decides whether to allow or deny traffic flows based on a defined set of security rules. Firewalls can be physical hardware devices, software, or both. What is network security management? Network security management lets network administrators manage their network, whether on-premises, in the cloud, or a hybrid network, consisting of physical and virtual single and multi-vendor firewalls. What are some challenges in network security management? Network administrators need to get clear and comprehensive visibility into network behavior, automate single and multi-vendor device configuration, enforce global network security policies, view network traffic, and generate audit-ready compliance reports across their entire network. Network administrators must continuously deploy security policies across the network. Yet, there may be thousands of firewall policies accumulated over the years. Frequently, they are cluttered, duplicated, outdated, or conflict with new rules. This can adversely affect the network’s security and performance.

Ensure your firewall meets all PCI DSS requirements. Learn essential best practices for configuring and managing your firewall for optimal PCI compliance. Firewall PCI DSS compliance: Requirements & best practices What is a firewall PCI DSS compliance? PCI DSS compliance refers to a set of security measures that apply to businesses handling payment cards, e.g., credit cards, debit cards, and cash cards. The full meaning of the term PCI DSS is Payment Card Industry Data Security Standard. All companies that accept, process, store, or transmit credit card information require PCI Compliance as it ensures data security during and outside financial transactions. PCI DSS compliance is the rules and policies companies processing, storing, or transmitting payment card information must adhere to, helping them build a secure environment for card data. The PCI security standards council (PCI SSC) is the body responsible for managing PCI DSS. PCI SSC was formed in 2006 and has since been providing policies that tackle evolving cyber threats in the payment card industry. A firewall PCI DSS compliance refers to the process of configuring a firewall to monitor and filter incoming and outgoing internet traffic based on PCI DSS policies. Firewalls function based on a set of security rules, enabling them to block bad traffic like viruses and hackers from penetrating your network. Establishing a PCI-compliant firewall gives companies robust payment card information security that meets business needs and effectively protects sensitive data. Schedule a Demo What are the benefits of a PCI-compliant firewall? Hackers see credit cards and other payment card types as money-making opportunities. They tirelessly attack systems and networks to extract cardholders’ personal information and sensitive authentication data, which they can exploit. Examples of cardholder data are: Primary Account Number (PAN) Cardholder name Expiration date Service code Sensitive authentication data include: Full track data (magnetic-stripe data or equivalent on a chip) CAV2/CVC2/CVV2/CID PINs/PIN blocks Becoming PCI-compliant means you have effective security solutions to help defend your network against attacks and protect the financial and personal data of payment cards. A PCI-compliant firewall has been configured following PCI policies to allow specific network traffic and block others from accessing card data. Some benefits of having a PCI-compliant firewall in your organization include: Builds customer trust Any business that stores, processes, accepts, or transmits credit card information must have a reliable cybersecurity solution to gain customers’ trust. Users want reassurance that their data is safely stored and transmitted in your organization’s network, backed by the strictest information security policy. By showing that your business meets international standards for card information security, you can easily build customer trust and increase patronage. Prevents data breaches The primary benefit of PCI DSS compliance is that it eliminates the risks of data breaches. Data breaches can lead to huge financial losses and even damage a company’s reputation. Often, hackers look for easy targets, and one quick way to find them is by checking for companies whose firewall configuration isn’t PCI-compliant. Being PCI-compliant shows any potential attacker that your network security is top-notch, thus discouraging them from taking any further action. It displays that your cardholder data environment is protected by formidable security solutions that meet industry regulations and best practices. Helps you to meet global standards PCI DSS compliance was put together by the PCI Security Standards Council (PCI SSC). The body was formed by Visa, MasterCard, Discover, American Express, and JCB– the top five payment card firms. They designed this payment card information security policy to prevent data breaches and protect network system components, including servers, firewalls, etc. Building a PCI-compliant firewall confirms that your business aligns with the most trusted payment firms and meets global cybersecurity standards for payment cards. Prevents fines and penalties Besides the financial loss that hackers directly cause from data breaches, companies may also suffer heavy fines and penalties. They may be required to foot card replacement bills, audit fees, investigation costs, and even compensate for customers’ losses. Every business that processes, stores, accepts, or transmits payment card data must meet the ideal security standards required to avoid fines and penalties. More importantly, becoming compliant helps you establish a good reputation for your business online and offline. Puts security first A compliant firewall enjoys round-the-clock security as it is fully configured to regulate physical access and network-based attacks. So even if there’s an internal malicious actor, you can still secure your customers and prevent unauthorized access. This attitude of putting security first across your IT infrastructure can save you from losses worth hundreds of thousands of dollars in the long run. Maximum speed functionality Organizations that deploy industry-standard firewall policies can function at maximum speed as they’re assured they have a secure network. Working at full speed enables goods or service providers to generate greater revenue as they can satisfy more customers within a short time. Plus, PCI firewall rules don’t only protect the Cardholder Data Environment against attacks, but they also improve your system’s operational efficiency. As a result, you generate maximum ROI from your investment. Schedule a Demo How does PCI compliance affect my business? As a business handling, storing, processing, or transmitting payment card data, it’s essential to prioritize building trust and a positive reputation. This is because customers prefer to do business with brands they trust to provide top security for their card information. Unarguably, being PCI-compliant is one of the core ways to show customers and partners that your business can be trusted. It makes them understand that your security posture meets international standards and can withstand tough security threats. Also, with your compliance certification, you gain a competitive advantage over many other businesses as statistics show that only about 36% of businesses are PCI-compliant. Being compliant allows you to compete with top brands by displaying the alignment of your card data security with the best industry practices. More interestingly, PCI compliance allows every component of your network environment to function optimally, thus giving an impressive and satisfactory output. Schedule a Demo How should the PCI DSS firewall configuration be? PCI DSS firewall should be configured in line with standard practices to protect Cardholder Data Environments (CDE) effectively. You must first regulate the flow of traffic to gain more control and create an effective risk management strategy that prevents cybercriminals from impacting your network. Organizations with a highly complex CDE may resort to segmentation using multiple firewalls, which involves separating systems for better control. Here’s how the PCI DSS firewall should be configured: Set security : Every switch port should have security settings, especially when following segmentation practices. You must set firewalls at the CDE boundaries and also between untrusted networks and the demilitarized zone (DMZ). The DMZ is a sub-network providing an extra layer of security to your internal private network. Establish rules: Set and regularly update firewall rules so that systems and system ports are only accessed by authorized sources. All wireless networks should have perimeter firewalls installed to prevent access from outside the defined environment. Outdated software programs and default passwords should also be avoided during configuration. Inbound/outbound rules: Determine what traffic should be allowed to enter or exit your network based on business needs. Firewalls should only allow traffic needed in the CDE, while other unnecessary traffic must be blocked. Also, direct traffic from the CDE to the Internet should be blocked to avoid creating a loophole. Use VPNs: remote users accessing the system should do so via virtual private networks (VPNs). Also, their portable devices (laptops, desktops, or smart devices) should have firewalls installed. Add/Close switch ports : You should use switch ports (e.g., Internet, office, CDE) to segment different networks. Also, ensure that end users can’t alter the firewall’s configuration on devices and that their management procedures are well-documented. Schedule a Demo Twelve requirements to become PCI-compliant? Every company that aims to achieve PCI compliance must fulfill the twelve PCI DSS compliance requirements. Doing this ensures that your organization’s network enjoys top-tier security controls against any cybersecurity threat. Below are the PCI DSS requirements. 1. Install a firewall and maintain it The first step toward becoming PCI-compliant is installing and maintaining a firewall. Proper firewall configuration will effectively block all untrusted networks attempting to penetrate your system to steal data. Businesses must configure their firewalls, routers, and other network security devices through industry standard rules to ensure they filter inbound and outbound traffic effectively. Inbound traffic is traffic originating from outside your network and attempting to penetrate it, while outbound traffic comes from within your network and goes out. It’s crucial to have standard inbound and outbound firewall rules to protect the network against malicious incoming traffic, such as malware, denial-of-service (DoS) attacks, etc. With firewalls, routers, and other components properly configured, your first line of defense is optimized for card data protection. 2. Initiate strong password protections Third-party components in your IT infrastructure, such as servers, network devices, point of sale (PoS) systems, applications, access points, etc., must be protected with strong passwords. Avoid using vendor-supplied defaults or generic passwords because they are simple and can be guessed easily. In fact, many of them are published online, hence why changing them to stronger passwords is a requirement. You must also have a list of the devices and software that require a password or any other security feature in your network. Plus, you should document your company’s configuration procedures from the time you obtain the third-party product until it enters your IT network. Doing this helps in vulnerability management so that you will take all required security measures each time you introduce a new component to your IT infrastructure. 3. Protect the data of cardholders The essence of becoming PCI-compliant is to protect cardholder data, and that’s why this third requirement is the most important of all. Companies must know the type of data they want to store, its location, and the retention period. Knowing the type of data you want to store helps in determining the most secure way to protect it. Encryption can protect all data through industry-accepted algorithms, truncation, or tokenization. Typically, two-layer protection is considered the best, such as using both encryption and tokenization. You must conduct regular maintenance and scanning to detect any unencrypted primary account numbers (PAN) and ensure that your PCI DSS encryption key management process is strong. As part of the third requirement, businesses should follow standard security controls when displaying primary account numbers. Ideally, only the first six and last four digits can be displayed. 4. Encrypt data that gets transmitted When data is transmitted across open, public networks like the Internet, WiFi, and Bluetooth, it must be encrypted. Failure to encrypt data puts it at great risk, as cybercriminals can often access such data. However, with proper encryption, you can maintain top security for your data at rest and in transit. Also, you should know the destination and source of card data to avoid sending or receiving data from untrusted networks. 5. Install and maintain anti-virus software Companies must install and maintain anti-virus software to protect against malware that can impact system performance. All systems and devices (e.g., laptops, desktops, mobile devices, workstations, etc.) providing local and remote IT network access should have anti-virus programs installed on them. These devices are commonly affected by malware which disrupts system functionality and allows unauthorized access to your network. Nonetheless, with an active and up-to-date anti-virus or anti-malware program, you can detect known malware, protect your system from malicious actors, and have more access control. 6. Update your systems and software The next layer of requirement is the update and maintenance of systems and applications. You should define and implement a process that identifies security risks from anti-virus programs to firewalls. This process should deploy a reliable third-party source to classify these security risks and send notifications for any newly discovered vulnerabilities in the PCI DSS environment. To ensure effective vulnerability management, you should patch (update) all systems, especially those that store or interact with the cardholder data. Examples of other systems that should be patched regularly include routers, application software, switches, databases, and POS terminals. Timely patching helps you resolve any vulnerabilities or bugs (errors) in your system before bad actors take advantage of them. 7. Restrict access to data Access control is a huge criterion when it comes to achieving PCI compliance. Employees should only have access to the data required to fulfill their roles and meet business needs. In other words, access to card data and systems should strictly be on a need-to-know basis. All staff who do not need cardholder data to execute their roles should be restricted from accessing it to prevent unnecessary exposure of sensitive data. Also, you must have a comprehensive list of all staff who need card data and their roles. Other details to document include: role definition current privilege level expected privilege level data resources required by each user to execute operations on card data. 8. Establish unique IDs for those with access After determining users who need access to cardholder data, you’re required to establish unique IDs for each of them. Some organizations use shared/group passwords for staff, which makes it challenging to track certain activities. Such organizations must switch to having unique IDs for each authorized user to fulfill the eighth requirement for PCI DSS compliance. A two-layer authentication must be implemented for every non-console administrative access (remote access). Establishing a complex and unique ID for each person with access to card data allows you to trace any unusual activity to their respective users. Thus, every user can take responsibility for their actions and be summoned for accountability or even face the necessary disciplinary actions for their security errors. If there’s a security threat, unique IDs enable swift response before serious damage is done. 9. Physical access needs to be limited Physical access to systems with cardholder data must be restricted to prevent data theft, manipulation, or destruction. The systems must be locked in a secure location (in a room, drawer, or cabinet). You should monitor the entry and exit doors of physical locations like data centers using surveillance cameras or electronic access controls. All physical access to systems with cardholder data must be kept in a log and retained for at least 90 days. Companies should allow only authorized visitors in the area and keep a document of their activities. Whenever an employee is switching roles or during resignation, all company-related systems with cardholder data or access to your internal network should be retrieved. Finally, on the restriction of physical access, you must destroy any media or device that’s no longer needed in your system. 10. Establish and maintain access logs One very common non-compliance challenge is the establishment and maintenance of access logs. Organizations must have a proper record-keeping and documentation process for all activities across their network, including data flow and access frequency. The collected information about access logs and other activities should be reviewed daily to detect and address any irregular actions. This requirement mandates that the collected information must meet the standard and be taken in real-time to enhance the audit phase. 11. Scan and perform tests to identify vulnerabilities Hackers understand that every system has a degree of vulnerability, and that’s why they tirelessly try new methods to help them penetrate networks and steal data. However, with frequent vulnerability scans and penetration testing, you can stay on top of cyber threats and keep users’ payment card details safe at all times. Vulnerability scans can help you discover any possible error in software programs and your entire security system. With penetration testing, you can discover your IT infrastructure’s weaknesses using the same tools and techniques as hackers. As a result, you will be able to block any loopholes in your physical and wireless networks before cybercriminals detect them. 12. Document your policies The last requirement for PCI DSS compliance relates to the documentation of information security policies. The policies must be reviewed annually and forwarded to the right persons (such as employees, vendors, etc.) to tackle evolving cyber threats effectively. Some important information to include during documentation includes your inventory of equipment, the process of information flow and storage, software, employees with access to sensitive data, etc. As part of fulfilling the last requirement, you must: Perform a formal risk assessment to determine critical assets, threats, and vulnerabilities. Conduct user awareness training Run employee background checks Perform incident management Schedule a Demo How AlgoSec helps with PCI DSS compliance Achieving PCI DSS compliance is one big step toward success for any business storing, processing, accepting, or transmitting payment card information.

For example, this ️ Docker Hub image contains critical vulnerabilities in 28 packages. Schedule a Demo ML classifier for malware Any x32/x64 ELF executable files created both during container image build phase and the runtime are scanned with Prevasio’s Machine Learing (ML) model. The ML model used by Prevasio relies on ELF file’s static characteristics, its entropy, and the sequence of its disassembled code. Here is an example of a malicious container image hosted️ at Docker Hub, that was picked up by Prevasio’s ML Classifier. Let’s see what happens if we recompile Mirai bot’s source code️ , by using custom domains for C2 (command-and-control) traffic. The Dockerfile with instructions to fetch, modify, and compile Mirai source code is available here️ . As you see in this example, the use of ML provides resistant detection, even if the malware was modified. Schedule a Demo Automated Pen-Test Full static visibility of the container’s internals is not sufficient to tell if a container image in question is safe indeed. During the last stage of its analysis, Prevasio Sandbox simulates attackers’ actions, first trying to fingerprint services running within the analysed container, and then engaging exploits against them. In addition to that, the pen-test performs a brute-force attack against an identified service (such as SSH, FTP or SQL), in order to find weak credentials that would allow the attackers to log in. As the pen-test is performed in an isolated environment, it poses no risk to the production environment. The following example demonstrates how the automated pen-test has identified the type of MySQL server running inside a container spawned from this️ Docker Hub image, then successfully brute-forced it and found working credentials against it.

Learn about the essential firewall change management process. Understand how to implement, track, and control changes to your firewall configurations for optimal security and compliance. Firewall change management process: How does It work? Are network firewalls adequately managed in today's complex environment? For more than two decades, we have been utilizing network firewalls, yet we’re still struggling to properly manage them. In today’s world of information-driven businesses there’s a lot more that can go wrong— and a lot more to lose—when it comes to firewalls, firewall policy management and overall network security. Network environments have become so complex that a single firewall configuration change can take the entire network offline and expose your business to cyber-attacks. Schedule a Demo Why you need firewall change management processes Improperly managed firewalls create some of the greatest business risks in any organization, however often you don’t find out about these risks until it is too late. Outdated firewall rules can allow unauthorized network access which result in cyber-attacks and gaps in compliance with industry and government regulations, while improper firewall rule changes can break business applications. Often, it is simple errors and oversights in the firewall change management process that cause problems, such as opening the network perimeter to security exploits and creating business continuity issues. Therefore, firewall configuration changes present a business challenge that you need to address properly once and for all. Schedule a Demo Firewall change management FAQs Frequently asked questions about the firewall change management process How can I manage firewall changes? In IT, things are constantly in a state of flux. The firewall change management process is one of the biggest problems that businesses face, however, if you can manage the firewall configuration changes consistently over time, then you’ve already won half the battle. You’ll not only have a more secure network environment, but you will allow IT to serve its purpose by facilitating business rather than getting in the way. To manage firewall changes properly, it’s critical to have well-documented and reasonable firewall policies and procedures, combined with automation controls, such as AlgoSec’s security policy management solution, to help with enforcement and oversight. With AlgoSec you can automate the entire firewall change management process: Process firewall changes with zero-touch automation in minutes, instead of days – from planning and design through to deployment on the device – while maintaining full control and ensuring accuracy Leverage topology awareness to identify all the firewalls that are affected by a proposed change Proactively assess the impact of every firewall change before it is implemented to ensure security and continuous compliance with regulatory and corporate standards Automate rule recertification processes while also identifying firewall rules which are out of date, unused or unnecessary Reconcile change requests with the actual changes performed, to identify any changes that were performed “out of band” Automatically document the entire firewall change management workflow It is also important to analyze the impact firewall changes will have on the business. The ideal way is to utilize AlgoSec’s firewall policy management solution to test different scenarios before pushing them out to production. Once AlgoSec and your processes are integrated with your overall change management workflow, you can set your business up for success instead of creating a “wait and see” situation, and “hoping” everything works out. Simply put, if you don’t have the proper insight and predictability, then you’ll set up your business and yourself for failure. How can I assess the risk of my firewall policies? As networks become more complex and firewall rulesets continue to grow, it becomes increasingly difficult to identify and quantify the risk caused by misconfigured or overly permissive firewall rules. A major contributor to firewall policy risks is lack of understanding of exactly what the firewall is doing at any given time. Even if traffic is flowing and applications are working, it doesn’t mean you don’t have unnecessary exposure. All firewall configuration changes either move your network towards better security or increased risks. Even the most experienced firewall administrator can make mistakes. Therefore, the best approach for minimizing firewall policy risks is to use automated firewall policy management tools to help find and fix the security risks before they get out of control. Automated firewall policy management tools, such as AlgoSec, employ widely-accepted firewall best practices and can analyze your current environment to highlight gaps and weaknesses. AlgoSec can also help tighten overly permissive rules (e.g., “ANY” service) by pinpointing the traffic that is flowing through any given rule. Combining policy analysis with the right tools allows you to be proactive with firewall security rather than finding out about the risks once it’s too late. How can I maintain optimized firewall rulesets? Maintaining a clean set of firewall rules is one of the most important functions in network security. Unwieldy rulesets are not just a technical nuisance—they also create business risks, such as open ports and unnecessary VPN tunnels, conflicting rules that create backdoor entry points, and an enormous amount of unnecessary complexity. In addition, bloated rulesets significantly complicate the auditing process, which often involves a review of each rule and its related business justification. This creates unnecessary costs for the business and wastes precious IT time. Examples of problematic firewall rules include unused rules, shadowed rules, expired rules, unattached objects and rules that are not ordered optimally (e.g. the most hit rule is at the bottom of the policy, creating unnecessary firewall overhead). Proactive and periodic checks can help eliminate rule base oversights and allow you to maintain a firewall environment that facilitates security rather than exposes weaknesses. To effectively manage your firewall rulesets, you need the right firewall administrator tools, such as AlgoSec, that will provide you with the visibility needed to see which rules can be eliminated or optimized, and what the implications are of removing or changing a rule. AlgoSec can also automate the change process, eliminating the need for time-consuming and inaccurate manual checks. You also need to ensure that you manage the rulesets on all firewalls. Picking and choosing certain firewalls is like limiting the scope of a security assessment to only part of your network. Your results will be limited, creating a serious false sense of security. It’s fine to focus on your most critical firewalls initially, but you need to address the rulesets across all firewalls eventually.
