Learn how firewall rules secure your network from cyber threats. Explore types, best practices, and management strategies to optimize your firewall security. Firewall rules & requirements (inbound vs. outbound) How to secure your network from threats? The cybersecurity landscape is increasingly volatile, with a massive rise in cyberattacks. Malicious cyber actors are relentlessly scouring the internet for vulnerable networks. Any company that wants to keep its network secure must implement a network security solution – a firewall. Cyber attackers keep evolving and finding ways to compromise security systems. As a result, companies need to implement and maintain security best practices. Installing a firewall is not enough; you have to take a step further to ensure the firewall rules are up-to-date and properly managed. If you want to learn how firewall rules work and secure your network from threats, keep reading! This article covers everything you need to know, including types of firewall rules, examples of firewall rules, and firewall rule best practices. Schedule a Demo What are firewall rules? Firewall rules are the major components of firewall policies that determine which types of traffic your firewall allows in and out of your network, and which are blocked. They are access control mechanisms that firewalls use to protect your network from being infiltrated by malicious or unauthorized traffic. Firewall rules examine the control information in individual packets, and either block or allow them based on a set of rules or predetermined criteria. These predetermined criteria or rule components include a source IP address, a destination IP address, ports, protocol type (TCP, UDP, or ICMP), and services. Firewall rules control how the firewalls prevent malicious programs and unauthorized traffic from compromising your network. So properly managing your firewall rules across your infrastructures is instrumental to securing your network from threats. Schedule a Demo How do firewall rules work? A firewall examines each incoming and outgoing data packet and matches it against the firewall rules. A packet is allowed to go through to its destination if it matches one of the rules that allow traffic. If a packet matches none of the rulesor hit a rule with deny, it is rejected. The rejection or mismatch is reported if the firewall is configured to do so. Firewalls are programmed to work with access control lists (ACLs). ACLs contain lists of permissions that determine network traffic that is allowed or blocked. An access control list details the conditions a data packet must meet before the ACL action (allow, deny, or reject) can be executed. To help you understand how firewall rules work, here’s a practical example: if a firewall rule states that traffic to destination N should be allowed only if it is from IP address M, the firewall will check the packet source and destination of incoming packets, and allow packets that meet the M & N rule to go through. If its packet’s destination is N but its source is unidentified or different from M, it is blocked. Packets are checked against firewall rules from top to bottom, and the first rule that matches the packet overrides the other rules below. The last rule is Deny Rest. This means that all packets not expressly permitted by the rules are blocked. You can create a firewall rule in pfSense. pfSense is an open-source firewall and router with unified threat management, load balancing, multi-WAN, a DNS Resolver, and a VPN. It supports a wide range of network technologies, including IPv4 & IPv6 addresses and pfBlockerNG. Other firewalls you can use to create firewall rules include Zenarmor, Windows Defender, and iptables. Schedule a Demo Why are firewall rules important? Firewall rules help network administrators to regulate access to networks. With firewall rules, you can determine what is allowed in and out of your network. For example, they prevent dangerous files like worms and viruses from accessing your network and consuming bandwidth. When it comes to protecting devices that operate within your network, firewall rules establish an essential line of defense. Firewalls (and other security measures like endpoint protection and security certifications) prevent malicious actors from accessing and compromising devices connected to your network or operating inside your network’s environment. Firewall rules help you comply with regulatory standards. Depending on your industry, relevant regulatory agencies expect your company to maintain a certain level of security. For example, if your business is located in the EU region or collects personal data of EU citizens, it is mandated to comply with GDPR. Schedule a Demo What are the main types of firewall rules? There are various types of firewall rules. They are categorized based on the type of security architecture under consideration. That being said, here are some of the major types of firewall rules: 1. Access rule As the name implies, this firewall rule blocks or grants access to inbound and outbound traffic based on certain conditions. The source address, destination address, port number, and protocol are key information that the access rule evaluates to determine whether access should be given or denied. 2. Network address translation (NAT) rule NAT helps you hide the original IP address of a private network – enabling you to protect your network. It makes traffic routing easier and smoothens the inflow & outflow of traffic to and from your network. 3. Application level gateways This type of firewall rule enables network administrators to implement policies that protect your internal network. Application-level gateways function as shields or gatekeepers between your internal network and the public internet. Administrators use them to regulate access to public networks, block some sites, limit access to certain content, and regulate devices allowed to access your network. 4. Stateful packet filtering This rule evaluates data packets and filters them against preset conditions. The traffic is denied access if it fails to meet the requirements outlined by the predetermined security criteria. 5. Circle-level gateways Circle-level gateways do not filter individual packets but rather monitor TCP handshakes to determine whether a session is legitimate and the remote system is considered trusted. Consequently, these gateways provide anonymity to your internal network. Schedule a Demo What is an example of a firewall rule? Firewall rules frequently consist of a source address, source port, destination address, destination port, and an action that determines whether to Allow or Deny the packet. In the following firewall ruleset example, the firewall is never directly accessed from the public network. This is because hackers who can directly access the firewall, can modify or delete rules and allow unwanted travel. Source addressSource portDestination addressDestination portAction AnyAny10.10.10.1AnyDenyAnyAny10.10.10.2AnyDeny10.10.10.1AnyAnyAnyDeny10.10.10.2AnyAnyAnyDeny In the following firewall ruleset example, all traffic from the trusted network is allowed out. This ruleset should be placed below the ruleset above. Since firewall rules are checked from top to bottom, specific rules should be placed before rules that are more general. Source addressSource portDestination addressDestination portAction 10.10.10.0AnyAnyAnyAllow Schedule a Demo What are the best ways to manage firewall rules? Effective management of firewall rules is necessary to avoid conflicting configurations and ensure your security infrastructure is powerful enough to ward off malicious attacks. To manage firewall rules better, do the following: ● Maintain proper documentation Properly document policies, rules, and workflows. It’s difficult for your network administrators to stay organized and manage firewall rules without proper documentation. Implement a strict documentation policy that mandates administrators to document policies and configuration changes. This improves visibility and ensures seamless continuity even if a key network operator leaves the company. ● Assign tasks with caution Ensure that only well-trained network operators have the privilege to assign and alter firewall rules. Allowing everyone on your security team to assign and change firewall rules increases the chances of misconfiguration. Giving such a privilege to a select few does the opposite and makes containing mismanagement easier. ● Use a standardized naming convention It’s easy to get confused about which configuration does what. This is more likely to happen where there is no naming convention. To avoid conflicting configurations, name each rule to clarify its purpose. By clearly defining the rules, conflicts can be easily resolved. ● Flag temporary rules Some rules are created to function just for a while – temporary rules. To keep things simple and ‘neat,’ flag temporary rules so they can be eliminated when they are no longer required. ● Order your rules Order rules in a specific pattern. For example, begin with global rules and narrow down to user-specific rules. ● Use a firewall management solution Many administrators use a firewall management and orchestration solution to streamline the firewall rule management process. The solution integrates with your firewall and uses built-in automation for managing firewall settings and configurations from a single dashboard. A firewall management tool helps you automate activities, gain visibility on all firewall rules, optimize firewall rules, remove rule anomalies, generate reports, etc. Schedule a Demo What are the best practices for firewall rules? To ensure your firewall works properly and offers the best security possible, there are some key best practices you have to follow when configuring and managing firewall rules: Review the firewall rules regularly The cyber threat landscape is always changing. Therefore, you must regularly review the firewall rules to ensure they provide optimal security against threats. Reviewing firewall rules helps you to be several steps ahead of malicious cyber actors, remove rule anomalies, and maintain compliance. Cyber attackers are relentlessly devising new ways to compromise security systems, infiltrate networks & subnets, and wreak havoc. You need to update the firewall rules regularly to counter new attacks. Obsolete rules can be maneuvered and the firewall compromised. You have to keep evolving the rules to stay ahead of malicious actors. Remove ineffective, redundant firewall rules. Are there rules that are no longer needed? Are there overlapping rules that are taking up space and confusing your network administrators? Look out for unnecessary configurations and remove them to free up the system and avoid confusion. In addition to helping you keep your network safe, reviewing firewall rules regularly also allows you to maintain compliance with regulatory standards such as HIPAA and GDPR. Keep tabs on firewall logs Keeping an eye on the firewall log helps administrators to monitor traffic flow, identify suspicious activities, and proactively fix challenges. Monitoring firewall logs gives you visibility into your infrastructure, enabling you to get to know your network users and the nature of their activities. Reduce complexity by categorizing firewall rules Make firewall rule structure simple and easy to manage by grouping rules with similar characteristics. This approach reduces configuration complexity, improves ease of administration, and optimizes firewall performance. Implement least-privileged access Do not grant users more privileges than necessary to perform their tasks. This ensures that only an authorized user can create a new rule, change a security policy, or gain access to specific resources. Block high-risk ports Blocking some ports can significantly decrease the risk of a network breach. The following table outlines the ports you should block as recommended by the SANS Institute .

Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 7/13/22 Published Eric Jeffery, AlgoSec’s regional solutions engineer, gives his view on the pivotal role of AppSec network engineers and how they can positively impact the business It may surprise many people but the number one skills gap hampering today’s application security network engineers is primarily centred around the soft skills which includes communication, writing, presentation, team building and critical thinking. Why is this so important? Because first and foremost, their goal is to manage the organization’s security posture by deploying the best application security tools and technologies for the specific security and growth needs of the business. Keep things safe but don’t get in the way of revenue generation What an application security network engineer should not do is get in the way of developing new business-critical or revenue generating applications. At the same time, they need to understand that they have a leadership role to play in steering a safe and profitable course for the business. Starting with an in depth understanding of all wired traffic, AppSec network engineers need to know what applications are running on the network, how they communicate, who they communicate with and how to secure the traffic and connectivity flow associated with each one of them. An AppSec network engineer’s expertise should extend much more than mastering simple applications such as FTP and SSH. Rather, business traffic continuity should sit at the pinnacle of their responsibilities. There’s a lot of revenue generating traffic that they need to understand and put the right guardrails to protect it. However, equally as important, they need to make sure that the traffic is not hindered by outdated or irrelevant rules and policies, to avoid any negative financial impact on the organization. Layers of expertise beyond the OSI model A good starting point for any AppSec network engineer is to acquire a commanding knowledge of the seven layers of the OSI model, especially Layer 6 which covers Presentation. In practical terms, this means that they should have a thorough understanding of the network and transport layers – knowing what traffic is going across the network and why. It’s also helpful to have basic scripting knowledge and an understanding of simple scripts such as a cron job for scheduling tasks. It could also be useful to know some basic level programming like Perl and PHP. Beyond the network skills, AppSec network engineers should grasp the business vertical in which they operate. Once they gain an understanding of the business DNA and the applications that make it tick, then they can add real value to their organizations. What’s on the network vs. what should be on the network Should AppSec network engineers be expected to understand business and applications? Absolutely. With this level of skill and knowledge, they can help the business progress securely by corelating what is actually in the network environment versus what should be in the environment. Once they have clear understanding, they can clean up then environment and optimize network performance with enhanced security. This becomes more critical as organizations grow and develop, often allowing too much unnecessary traffic into the environment. Typically, this is how the scenario plays out: Applications are added or removed (decommissioned), or a new vendor or solution is brought on board and the firewall turns into a de facto router. The end result of such often leads to new vulnerabilities and too many unnecessary threat vectors. This is precisely where the aforementioned soft skills come in – an AppSec network engineer should be able to call out practices that don’t align with business goals. It’s also incumbent upon organizations to offer soft skills training to help their AppSec network engineers become more valuable to their teams. Need an application view to be effective in securing the business When firewalls become de facto routers, organizations end up relying on other areas for security. However, security needs to be aligned with the applications to prevent cyber attacks from getting onto the network and then from moving laterally across the network, should they manage to bypass the firewalls. All too often, east-west security is inadequate and therefore, AppSec network engineers need to look at network segmentation and application segmentation as part of a holistic network security strategy. The good news is that there are some great new technologies that can help with segmenting an internal network. The lesser good news is that there’s a danger in the thinking that by bolting on new tools, the problem will be solved. So often these tools are only partially deployed before the team moves onto the next “latest and the greatest” solution. When exploring new technologies, AppSec network engineers must ask themselves the following: Is there a matching use case for each solution? Will procurement of another tool lead to securing the environment or will it just be another useless “flavor of the month” tool? Irregardless, once the new technology solution is acquired, it is imperative to align the right skilful people with this technology to enable the organization to intelligently secure the whole environment before moving onto a new tool. To further hone this point, celebrating the introduction of a new firewall is superfluous if at the end of the day, it does not utilize the right rules and policies. Ushering some of these new technologies without proper deployment will only leave gaping holes and give organizations a false sense of security, exposing them to continuous risks. Don’t put the cloud native cart before the horse The role of an AppSec network engineer becomes even more critical when moving to the cloud. It starts with asking probing questions: What are the applications in the business and why are we moving them to the cloud? Is it for scalability, speed of access or to update a legacy system? Will the business benefit from the investment and the potential performance impact? It’s also important to consider the architecture in the cloud: Is it containerized, public cloud, private cloud or hybrid? Once you get definitive answers to these questions, create reference architectures and get senior level buy-in. Finally, think about the order in which the enterprise migrates applications to the cloud and maybe start with some non-critical applications that only affect a small number of locations or people before risking moving critical revenue generating applications. Don’t put the cart before the horse. DevSecOps: We should be working together; you can be sure the criminals are… Network application security is complicated enough without introducing internal squabbles over resources or sacrificing security for speed. Security teams and development teams need to work together and focus on what is best for your business. Again, this where the soft skills like teamwork, communications and project management come into play. The bottom line is this: Understand bad actors and prepare for the worst. The bad guys are just chomping at the bit, waiting for your organizations to make the next mistake. To beat them, DevSecOps teams must leverage all the resources they have available. Future promise or false sense of security? There are some exciting new technologies to look forward to in the horizon to help secure the application environment. Areas like quantum computing, machine learning, AI and blockchain show great promise in outfoxing the cyber criminals in the healthcare and financial services industries. It is expected that the AppSec network engineer will play a vital role in the viability of these new technologies. Yet, the right technology will still need to be applied to the right use case correctly and then fully deployed to in order see any effective results. The takeaway So much of the role of the AppSec network engineer is about taking a cold hard look at the goals of the business and asking some challenging questions. It all starts with “what’s right for the business?” rather than “what’s the latest technology we can get our hands on?” To be an effective AppSec network engineer, individuals should not only know the corporate network inside out, but they also must have an overall grasp of applications and the applicable business cases they support. Furthermore, collaboration with developers and operations (DevOps) becomes an agent for rapid deployment of revenue generating or mission critical applications. But it still goes back to the soft skills. To protect the business from taking needless security risks and demand a seat at the decision-making table, AppSec network engineers need to apply strong leadership, project management and communications skills To learn more on the importance of AppSec network engineers to your organization’s cybersecurity team, watch the following video Schedule a demo Related Articles Q1 at AlgoSec: What innovations and milestones defined our start to 2026?

Cloud Security Router Honeypot for an IRC Bot 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. glibc_2 Tags Share this article 9/13/20 Published In our previous post we have provided some details about a new fork of Kinsing malware, a Linux malware that propagates across misconfigured Docker platforms and compromises them with a coinminer. Several days ago, the attackers behind this malware have uploaded a new ELF executable b_armv7l into the compromised server dockerupdate[.]anondns[.]net . The executable b_armv7l is based on a known source of Tsunami (also known as Kaiten), and is built using uClibc toolchain: $ file b_armv7l b_armv7l: ELF 32-bit LSB executable, ARM, EABI4 version 1 (SYSV), dynamically linked, interpreter /lib/ld-uClibc.so.0, with debug_info, not stripped Unlike glibc , the C library normally used with Linux distributions, uClibc is smaller and is designed for embedded Linux systems, such as IoT. Therefore, the malicious b_armv7l was built with a clear intention to install it on such devices as routers, firewalls, gateways, network cameras, NAS servers, etc. Some of the binary’s strings are encrypted. With the help of the HexRays decompiler , one could clearly see how they are decrypted: memcpy ( &key, "xm@_;w,B-Z*j?nvE|sq1o$3\"7zKC4ihgfe6cba~&5Dk2d!8+9Uy:" , 0x40u ) ; memcpy ( &alphabet, "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ. " , 0x40u ) ; for ( i = 0; i < = 64; ++i ){ if ( encoded [ j ] == key [ i ]) { if ( psw_or_srv ) decodedpsw [ k ] = alphabet [ i ] ; else decodedsrv [ k ] = alphabet [ i ] ; ++k; }} The string decryption routine is trivial — it simply replaces each encrypted string’s character found in the array key with a character at the same position, located in the array alphabet. Using this trick, the critical strings can be decrypted as: Variable Name Encoded String Decoded String decodedpsw $7|3vfaa~8 logmeINNOW decodedsrv $7?*$s7

success stories "We cut the time it takes to implement firewall rules by at least 50%" Application owners for global retail chain get faster response times with application visibility and automated deployment. Orange Cyberdefense is the expert cybersecurity business unit of the Orange Group, providing managed security, managed threat detection & response services to organizations around the globe. They embed security into Orange Business Services solutions with more than 250 security researchers and analysts and 16 SOCs distributed around the world supporting customers in over 160 countries. The Challenge Orange Cyberdefense is an on-site consultant for a large retail chain with hundreds of stores and hundreds of thousands of employees spread out across the world.The client has over 2,500 multi-vendor firewalls and Layer 3 devices in their global data centers. They also run hundreds of mission-critical business services. Business services include supply chain management and ERP systems, global eCommerce operations, financial management systems, and much more. As a result, they had to cope with hundreds of change requests daily.Some of the challenges included: Lack of centralized management – Multiple vendors’ firewalls are deployed, which were implemented by multiple third-party vendors. There was no validation that rules were consistently applied across multiple vendor’s management consoles. Commissioning and decommissioning devices – A mix of multi-vendor new and legacy devices run in the data center and maintaining consistency across multiple vendors and multiple versions of devices was difficult. Lack of automation – Firewall communication and traffic flows were described in Excel sheets and needed to be manually updated whenever there was a change. Slow execution of change requests – Implementing firewall changes took over a week. Poorly implemented rules – The rules did not reflect what the requester asked for. They either allowed too much traffic in or were too narrow, not allowing the required traffic and thus needed to be re-implemented. The Solution The client searched for a solution that provided: Faster implementation of firewall changes. Comprehensive firewall support for a globally dispersed multi-vendor, hybrid estate. Automation of security policy change management and documentation of security policy changes. Visibility into their business applications and traffic flows. They implemented the AlgoSec Security Policy Management Solution, made up of AlgoSec Horizon Security Analyzer, AlgoSec Horizon FireFlow, and AlgoSec Horizon AppViz and AppChange (formerly AlgoSec BusinessFlow). AlgoSec Horizon Security Analyzer analyzes complex network security policies across on-premise, cloud, and hybrid networks. It automates and simplifies security operations, including troubleshooting, auditing and risk analysis. Using Horizon Security Analyzer, the client can optimize the configuration of firewalls, and network infrastructure to ensure security and compliance. AlgoSec Horizon FireFlow enables security staff to automate the entire security policy change process from design and submission to proactive risk analysis, implementation, validation, and auditing. Its intelligent, automated workflows save time and improve security by eliminating manual errors and reducing risk. AlgoSec Horizon AppViz and AppChange (formerly AlgoSec BusinessFlow) discover, identify, and map business applications, providing critical security information regarding the firewalls and firewall rules supporting each connectivity flow. With AlgoSec AppChange, changes can be made at the business application level, including application migrations, server deployment, and decommissioning projects. The Results Some of the ways the client benefits from using AlgoSec include: Greater transparency by providing a single source of truth that took into consideration the entire network estate. 50% reduction in the time needed to implement firewall rules. More communication between network security/IT staff and business application owners who are now able to submit change requests in business language and easily describe their needs, thus reducing misconfigurations and potential breaches. Better compliance reporting – with both an easy API integration and also audit-ready compliance reports. Automated change management – network changes are now recorded while being made – not managed with Excel. By using AlgoSec, application owners have more visibility into the network and are better able to trace what has changed within their business applications. “Documentation is several hundred percent better this way,” said Hans Broomé, Network and Security Consultant at Orange Cyberdefense. “With many different versions of the services, by using AlgoSec the IT team is confident that they are making changes to the correct version.” There were even unexpected gains, such as improved security management procedures. Change requests became more accurate as they gained visibility into the network and made the change request process more systematic and transparent. Requesters, as well as stakeholders such as their managers, have full visibility of their change request’s status and can verify that the request works as intended. Orange Cyberdefense is also impressed with the dedicated attention they receive from AlgoSec. AlgoSec’s support team is familiar with the global organization and provides dedicated attention tailored to their exact needs. They stay up to date with the AlgoSec solution’s latest capabilities, and the technical team maximizes their use of it thanks to an extensive training library. “The best is yet to come,” concluded Broomé.

Leading payment solutions company credits AlgoSec for increasing security and compliance Organization Payment Solutions Industry Financial Services Headquarters Download case study Share Customer
success stories "Leading fintech company rapidly improves security and compliance with AlgoSec jumpstart program" Background The company is one of the largest payment solutions providers, with offices processing more than 28 billion transactions worldwide. The company services 800,000 merchant outlets that generate $120 billion in processing volume. Its businesses include credit card processing, merchant acquisition and issuance of bank credit cards. The company grew to its enormous size through innovation and acquisition. It has introduced modern technology into the payments industry and has acquired many innovative companies over the last three decades. Challenges Today, the company operates 10 data centers with varying security architectures and firewall equipment from different vendors. The security staff is currently in the process of a cross-company firewall consolidation that will take several years to complete. The company is automating its change management of firewall rules to cut down on the time and effort spent on researching and implementing rules to keep up with its fast growth. It deploys rule changes during tight, scheduled “push windows” and conducts compliance reviews twice per year. The firewall change process is highly complex with many steps: Request Design Peer Review Management Approval Implementation Validation Success for the security team is all about time. They seek to automate the process by reducing time spent on: Research and writing rules Peer reviews Staging Security peering after staging Firewall push window requirements Quarterly firewall ruleset reviews as part of compliance objectives Solution The security team acquired AlgoSec Horizon Security Analyzer (AFA) and deployed it at two of its data centers in Arizona and Colorado. In both locations, the company is in the process of firewall migration to consolidate on one vendor. However, they need to add firewall clusters one at a time after each migration instead of all at once. The company took advantage of AlgoSec’s Jumpstart Program that delivers the benefits of AlgoSec Horizon Security Analyzer in conjunction with other AlgoSec solutions quickly. With Jumpstart, the company is quickly able to: Automate the discovery and mapping of enterprise applications Automate the change management processes Adopt the new processes across the company Realize rapid ROI The company’s lead security infrastructure consultant proclaimed, “AlgoSec customized their Jumpstart Program just for us. Their people are engaged, personable, skilled and highly efficient. They became part of our team dedicated to our success.” In addition to getting Horizon Security Analyzer up and running quickly and delivering its benefits, the Jumpstart team’s AFA deployment immediately identified network security gaps and helped the company close them, making them more secure and compliant. Results AlgoSec Horizon Security Analyzer is achieving all the goals of the security team. Time for policy writing reduced from 90 hours to 15 hours – 83% less Cut the total process time by half, enabling the security team to keep up with the barrage of change requests. Reduced the admin overhead from 30 to 4 – 87% less “Automation is definitely the way to go,” declared their security consultant. “We can now stay on top of the process even while we migrate our firewalls. We are looking for more from AlgoSec.” The company is now in the process of implementing AlgoSec Horizon FireFlow (AFF) to enhance the existing change management system with intelligent network and security automation. AlgoSec Horizon FireFlow enforces compliance and automatically documents the entire change-management lifecycle. Some of the features include: Processing of firewall changes with zero-touch automation Elimination of mistakes and rework, and improvement of accountability for change requests Proactive assessment of the impact of network changes to ensure security and continuous compliance Automation of the rule–recertification processes Schedule time with one of our experts
