Background The customer is one of the world’s leading integrated energy companies. Through its worldwide subsidiaries, the company is involved in virtually every facet of the energy industry. The company explores for, produces and transports crude oil and natural gas; refines, markets and distributes transportation fuels and lubricants; manufactures and sells petrochemicals and additives; generates power; and develops and deploys technologies that enhance business value in every aspect of the company’s operations. They are listed on the Fortune 50 and a component of the S&P 100. The Challenge The customer has over 900 firewalls throughout the world, including in several remote sites. Some of their challenges included: Overly broad firewall policies Risky firewall rules Pressure from legal and compliance teams Manual processes and difficulty implementing automation Lack of visibility into security policies throughout the network “Before AlgoSec, we didn’t manage our firewalls very well,” stated Jeremy Haynes, a Solution Architect at the energy company. “We did not have a good enforcement and validation tool to verify that policies were accurate and did not introduce unacceptable risk.” The Solution The company was in the process of migrating from their previous firewall vendor to Palo Alto Networks. They used the opportunity for a fresh start to clean up and optimize their security policies. They were searching for a solution that provided: Automation of firewall policy management Identification of layer 7 (application-based) policies Innovative features that aligned with their strategic goals Strong support for Palo Alto Networks firewalls Following an in-depth evaluation, the company selected AlgoSec’s Security Policy Management Solution, which includes AlgoSec Horizon Security Analyzer and AlgoSec Horizon FireFlow (AFF). AlgoSec Horizon Security Analyzer ensures security and compliance by providing visibility and analysis into complex network security policies. AlgoSec Horizon FireFlow improves security and saves security staffs’ time by automating the entire security policy change process, eliminating manual errors, and reducing risk. The Results By using the AlgoSec Security Management Solution, the company was able to clean up risky firewall policies, reduce misconfigurations, and dedicate more workers to business-driven innovation instead of security policy maintenance. Some benefits gained include: Compliance with internal requirements Ability to map out their network and maintain network segmentation Less time needed to maintain firewall policies Easier time managing hundreds of firewalls spread out worldwide AlgoSec enabled their network segmentation initiatives. By mapping their network, and determining what zones should communicate with each other, they were able to fix existing policies that broke segmentation rules and not break segmentation policies in the future. This helped ensure a state of continuous compliance. “AlgoSec gives us an easy to read and present view of firewall compliance. This helps our business units ensure their policies are clean. We can also demonstrate that the firewalls connected to our network, but owned by other business units, meet our standards,” according to Haynes. They have over 1,700 change requests daily and therefore automation is crucial. “The ability to work with Ansible, ServiceNow, and Palo Alto gives us the ability to automate our firewall policy creation. It does so in a manner where we do not have to worry about a policy being created that may put our organization at risk,” continued Haynes. AlgoSec helps the company to not only quickly deploy firewall policies but also ensure the security of the business. “We want to make sure our money-making capabilities can conduct their business with minimal impact and do their job. The ROI for us is our great assurance in the security of our firewall policies,” concluded Haynes. Schedule time with one of our experts

Tags Share this article 8/9/23 Published If your firewall shows a notification that it has detected a new network, it means it is doing one of its fundamental jobs properly. But good network security does not stop with just detecting a new network. You will have to analyze the network location, ensure it is authorized to connect with your network, automate this process, and ensure full-on monitoring so that none of the intrusive attempts ever go unnoticed. A good amount of all these tasks can be made more efficient, accurate, and automated with the help of strong network security solutions. What should you do if your firewall has detected an unrecognized network? 1. Analyze the incoming network request If the process is not automated, you might have to check for the incoming network request’s trustworthiness manually. You can check the security certificates associated with the request, check its source, validate with the right information whether this source can be trusted, and then decide whether to allow access. The best way to deal with any new network detection is to automate the authorization by using a strong network security policy that outlines what sources can be trusted, what cannot be trusted, and which decisions require further approval. 2. Analyze your network for any impact In case of an untrusted new network detection and possible intrusion, you should be able to check the impact or effect it has had on your current assets. You should analyze the entire system for performance, feature validation, and asset availability. A quick way to do this would be to use any network visualization product, such as Horizon Security Analyzer . This tool can also assess how your overall home network will be impacted by any possible security policy 3. Reassess your security policies and improve them In the event of any security incident, you will have to isolate your network, mitigate any impact caused by the intrusion and reset the system to a healthy state. And most importantly, you will have to investigate the incident, figure out the root cause, and fix it. This would require updating your security policies, risk management, and local network security settings. Following up on any security incident is highly recommended so that no unauthorized intrusion attempts go unnoticed and are handled appropriately. And like any other seemingly enormous task, this can be automated too. Check out firewall change management tools to help you implement continuous improvement within your network security management, contributing to network protection. How to setup strong firewall protection Here are some security measures and troubleshooting tips you need to employ to strengthen your Microsoft firewall management and network security. 1. Establish a strong network security policy management To implement a strong network security management framework, you must design the security policies, systems, and solutions as per your operating system. A network security policy framework can help you guide and streamline the security design and guide you with the enforcement of the same. As with any process, policy management should also be a continuously evolving framework and must be managed well to facilitate all the relevant tasks. Use intelligent systems like Algosec’s Algobot to help your firewall admins to carry out their tasks efficiently. And if you are looking to automate the security policy management tasks, you can also check out Fireflow . It helps you automate the security policy change process across the many phases of policy management, from planning to implementation and validation. 2. Visualize the network data Network monitoring is critical to enabling t strong firewall While AI-based alerting and monitoring systems could greatly help automate intrusion detection and notification, certain tasks require human supervision and deep analysis of the network logs. This way, you can not only analyze the network for any intrusion attempts (whether it be through malware sent through a web browser, file sharing, router, ethernet network adapter, or wi-fi) but also get to have a good understanding of your traffic and business trends. Horizon AppViz from Algosec is a helpful tool for achieving this functionality. 3. Optimize your firewall configuration Firewall configurations include a broad range of activities that range from designing your firewall solution and choosing the right software/hardware to setting up the firewall rules and management processes. Set these configurations early on with all necessary considerations regarding your environment and applications. This process should also include the overall policy configurations and security rules that define the change process, firewall administration, monitoring, and management operations. Read this resourceful guide to learn more about firewall configuration, its challenges, and guidance on implementation. 4. Ensure cloud compliance Compliance and security go hand in hand in protecting your assets and boosting the overall goodwill and trust associated with your brand. Cloud compliance frameworks provide guidelines and cover most of the pain points of managing cloud security. Staying compliant with these guidelines means that your security is up to date and can be considered on par with the high standards set by these frameworks. 5. Micro-segmentation Micro-segmentation is a domain network security technique that helps you implement flexible security measures for individually segmented data center parts. It is most helpful with protecting your virtual machine implementations as it allows you to deploy specific security measures crafted to fit each virtual machine’s requirements. With security deployed on segmented workloads, your network becomes more resilient to attacks. 6. Perform regular firewall audits To ensure continuous compliance, you must conduct regular audit checks on the status of your firewall settings, policies, and implementations. Gather all the related documents and key information, review your current processes, firewall mechanisms, perform penetration tests, assess the security measures, and optimize as required. Perform a complete risk assessment on your Windows server and fix any issues that might be discovered as part of the audit process. Tips and best practices for enhanced network security 1. Firewall for native cloud applications Make use of cloud-first prioritized firewall solutions to protect your native cloud applications. You need comprehensive visibility on all your cloud assets, ensuring advanced threat detection and protection. This requires a whole set of tools and security applications working together to provide a centralized security system. You will also have to ensure data compliance at all levels as well. You can try to employ native cloud solutions such as the extensive tools provided by Algosec. 2. Use centralized solutions Make use of centralized solutions to manage hybrid and multi-cloud applications so that you have all the important information accessible from a single platform. AlgoSec Cloud from Algosec is an amazing solution to achieve centralized visibility across hybrid and multi-cloud accounts and assets. 3. Follow the best security practices and guidelines Look into the best security practices and guidelines put forth by your cloud vendor and follow them to get the best out of the collective knowledge. You can also use vendor-specific firewall management solutions to help you deal with issues related to specific cloud accounts you might be using. Additionally, having an antivirus like Windows Defender and using a VPN also helps. A good practice to follow in case of uncertainty is to block by default. Any new network or source must be blocked unless specifically permitted by the user. Regarding access privileges, you can follow the principle of least privilege, where users are only granted as many privileges as would be required for their specific roles and responsibilities. Use audit tools for regular auditing and keep improving on any vulnerabilities your firewall may have. To increase the performance of your firewall applications, you can look into how you have set up your firewall rules and optimize them for better performance. Here are some more best practices you can follow when setting up your firewall rules: Document all your rules and firewall configurations across all the devices. Make sure to document every new rule created and keep your documentation up to date. This can help security admins review the rules and optimize them as and when necessary. As mentioned earlier, follow a zero trust policy where you block traffic by default and permit network access only on a need basis. Monitor your firewall logs even when there is no particular security incident to investigate. Regular monitoring and analysis will give you a better understanding of your network traffic and can help you identify suspicious activities early on. Group the firewall rules to boost performance and avoid complications and loopholes. You can hire expert security administrators and security solutions such as Algosec to help review your firewall rules and keep them updated. Firewall management FAQs What can a firewall do? A Windows firewall can be interpreted as similar to a literal wall. It blocks unwanted access to your system and lets you decide whether or not to allow any new network connection or access request. Similar to how a fort works, you only give access to access requests that you trust and block the rest. It is the first defensive setup you can set up for your network security. You can set a list of trusted sources, and the requests from these sources will be given automated access. The rest of the access requests from any other source, be it a third-party network, mobile devices, internet connection, or any other endpoint, can be blocked by your firewall. You can set up firewall rules that dictate which type of requests and sources can be trusted. A firewall can be implemented by using multiple methods. It can be a cloud app, hardware, software, virtualizations, an access-restricted private cloud, and more. A typical firewall ruleset consists of the following specifications: Source address Source port Destination address Destination port Information on whether to block or permit the traffic to the respective address and port criteria. A firewall can be implemented by using multiple methods. It can be a cloud app, hardware, software, virtualizations, an access-restricted private cloud, and more. How does a firewall protect businesses from cyberthreats? The obvious main use of the firewall is to restrict all kinds of unauthorized access, thus protecting your systems from cyberattacks. But it also has several other benefits, such as: Providing data privacy so your work network traffic is guarded from outside public networks. Restricting content access to your private network For instance, educational institutions can block inappropriate sites for their students while in class. Blocking unwanted traffic from ads, spam, and gaming sites. Ensuring data confidentiality and keeping you compliant with security standards. Monitoring all your incoming traffic, helping you analyze your network profile, and helping you gain insights into trending user behavior. Filtering out unwanted traffic and restricting access to certain websites. Providing secure remote access through VPNs and similar remote access mechanisms. What are the most common types of firewalls? Based on the way data is filtered through a firewall, it can be broadly classified into one of the following types: Packet filtering Stateful inspection firewalls Circuit-level gateway firewalls Proxy firewalls Next-generation firewalls (NGFWs) Threat focused NGFWs Virtual firewalls Cloud-native firewalls Schedule a demo Related Articles Q1 at AlgoSec: What innovations and milestones defined our start to 2026?

Cyber Attacks & Incident Response How to Use Decoy Deception for Network Protection Matthew Pascucci 2 min read Matthew Pascucci Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 6/30/15 Published A Decoy Network The strategy behind Sun Tzu’s ‘Art of War’ has been used by the military, sports teams, and pretty much anyone looking for a strategic edge against their foes. As Sun Tzu says “All warfare is based on deception. Hence, when we are able to attack, we must seem unable; when using our forces, we must appear inactive; when we are near, we must make the enemy believe we are far away; when far away, we must make him believe we are near.” Sun Tzu understood that to gain an advantage on your opponent you need to catch him off guard, make him believe you’re something you’re not, so that you can leverage this opportunity to your advantage. As security practitioners we should all supplement our security practices with this timed and tested decoy technique against cyber attackers. There are a few technologies that can be used as decoys, and two of the most common are honeypots and false decoy accounts: A honeypot is a specially designed piece of software that mimics another system, normally with vulnerable services that aren’t really vulnerable, in order to attract the attention of an attacker as they’re sneaking through your network. Decoy accounts are created in order to check if someone is attempting to log into them. When an attempt is made security experts can then investigate the attackers’ techniques and strategies, without being detected or any data being compromised. Design the right decoy But before actually setting up either of these two techniques you first need to think about how to design the decoy in a way that will be believable. These decoy systems shouldn’t be overtly obvious, yet they need to entice the hacker so that he can’t pass up the opportunity. So think like an attacker: What would an attacker do first when gaining access to a network? How would he exploit a system? Will they install malware? Will they perform a recon scan looking for pivot points? Figuring out what your opponent will do once they’ve gained access to your network is the key to building attractive decoy systems and effective preventive measures. Place it in plain sight You also need to figure out the right place for your decoys. You want to install decoys into your network around areas of high value, as well as systems that are not properly monitored with other security technologies. They should be hiding in plain sight and mimicking the systems or accounts that they’re living next to. This means running similar services, have hostnames that fall in line with your syntax, running on the same operating systems (one exception is decoys running a few exploitable services to entice the attacker). The goes the same for accounts that you’ve seeded in applications or authentication services. We decided that in addition to family photos, it was time to focus on couples photoshoot ! Last fall we aired our popular City Photoshoot Tips & Ideas and as a result, gave you TONS of ideas and inspiration. And last but not least, you need to find a way to discretely publicize your applications or accounts in order to attract the attacker. Then, when an attacker tries to log in to the decoy applications or accounts (which should be disabled) you should immediately and automatically start tracking and investigating the attack path. Watch and learn Another important point to make is that once a breach attempt has been made you shouldn’t immediately cut off the account. You might want to watch the hacker for a period of time to see what else that he might access on the network. Many times tracking their actions over a period of time will give you a lot more actionable information that will ultimately help you create a far more secure perimeter. Think of it as a plainclothes police officer following a known criminal. Many times the police will follow a criminal to see if he will lead them toward more information about their activities before making an arrest. Use the same techniques. If an attacker trips over a few of carefully laid traps, it’s possible that he’s just starting to poke around your network. It’s up to you, while you have the upper hand, to determine if you start remediation or continue to guide them under your watchful eye.

So we’ve made it to the last part of our blog series on PCI 3.0 Requirement 1. The first two posts covered Requirement 1.1... Auditing and Compliance Avoid the Traps: What You Need to Know About PCI Requirement 1 (Part 3) Matthew Pascucci 2 min read Matthew Pascucci Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 9/9/14 Published So we’ve made it to the last part of our blog series on PCI 3.0 Requirement 1. The first two posts covered Requirement 1.1 (appropriate firewall and router configurations) and 1.2 (restrict connections between untrusted networks and any system components in the cardholder data environment) and in this final post we’ll discuss key requirements of Requirements 1.3 -1.5 and I’ll again give you my insight to help you understand the implications of these requirements and how to comply with them. Implement a DMZ to limit inbound traffic to only system components that provide authorized publicly accessible services, protocols, and ports (1.3.1.): The DMZ is used to publish services such as HTTP and HTTPS to the internet and allow external entities to access these services. But the key point here is that you don’t need to open every port on the DMZ. This requirement verifies that a company has a DMZ implemented and that inbound activity is limited to only the required protocols and ports. Limit inbound Internet traffic to IP addresses within the DMZ (1.3.2): This is a similar requirement to 1.3.1, however instead of looking for protocols, the requirement focuses on the IPs that the protocol is able to access. In this case, just because you might need HTTP open to a web server, doesn’t mean that all systems should have external port 80 open to inbound traffic. Do not allow any direct connections inbound or outbound for traffic between the Internet and the cardholder data environment (1.3.3): This requirement verifies that there isn’t unfiltered access, either going into the CDE or leaving it, which means that all traffic that traverses this network must pass through a firewall. All unwanted traffic should be blocked and all allowed traffic should be permitted based on an explicit source/destination/protocol. There should never be a time that someone can enter or leave the CDE without first being inspected by a firewall of some type. Implement anti-spoofing measures to detect and block forged source IP addresses from entering the network (1.3.4): In an attempt to bypass your firewall, cyber attackers will try and spoof packets using the internal IP range of your network to make it look like the request originated internally. Enabling the IP spoofing feature on your firewall will help prevent these types of attacks. Do not allow unauthorized outbound traffic from the cardholder data environment to the Internet (1.3.5): Similar to 1.3.3, this requirement assumes that you don’t have direct outbound access to the internet without a firewall. However in the event that a system has filtered egress access to the internet the QSA will want to understand why this access is needed, and whether there are controls in place to ensure that sensitive data cannot be transmitted outbound. Implement stateful inspection, also known as dynamic packet filtering (1.3.6): If you’re running a modern firewall this feature is most likely already configured by default. With stateful inspection, the firewall maintains a state table which includes all the connections that traverse the firewall, and it knows if there’s a valid response from the current connection. It is used to stop attackers from trying to trick a firewall into initiating a request that didn’t previously exist. Place system components that store cardholder data (such as a database) in an internal network zone, segregated from the DMZ and other untrusted networks (1.3.7): Attackers are looking for your card holder database. Therefore, it shouldn’t be stored within the DMZ. The DMZ should be considered an untrusted network and segregated from the rest of the network. By having the database on the internal network provides another layer of protection against unwanted access. [Also see my suggestions for designing and securing you DMZ in my previous blog series: The Ideal Network Security Perimeter Design: Examining the DMZ Do not disclose private IP addresses and routing information to unauthorized parties (1.3.8): There should be methods in place to prevent your internal IP address scheme from being leaked outside your company. Attackers are looking for any information on how to breach your network, and giving them your internal address scheme is just one less thing they need to learn. You can stop this by using NAT, proxy servers, etc. to limit what can be seen from the outside. Install personal firewall software on any mobile and/or employee-owned devices that connect to the Internet when outside the network (for example, laptops used by employees), and which are also used to access the network (1.4): Mobile devices, such as laptops, that can connect to both the internal network and externally, should have a personal firewall configured with rules that prevent malicious software or attackers from communicating with the device. These firewalls need to be configured so that their rulebase can never be stopped or changed by anyone other than an administrator. Ensure that security policies and operational procedures for managing firewalls are documented, in use, and known to all affected parties (1.5): There needs to be a unified policy regarding firewall maintenance including how maintenance procedures are performed, who has access to the firewall and when maintenance is scheduled. Well, that’s it! Hopefully, my posts have given you a better insight into what is actually required in Requirement 1 and what you need to do to comply with it.
