success stories "AlgoSec now does the heavy lifting for us. It allows the engineers to focus more on providing greater levels of security than on process and change, so we’re able to provide a much more secure infrastructure for BT" Background A leading world-wide provider of communications services and solutions, BT serves customers in more than 170 countries. Its principal activities include the provision of networked IT services globally; local, national and international telecommunications services for use at home, at work and on the move; broadband, TV and internet products and services; and converged fixed/mobile products and services. Challenge BT’s internal network is a complex, highly segmented environment that has evolved over the last two decades throughout its worldwide locations. BT’s infrastructure relies on a large number of third-party domains and business-to-business connections with over 1,000 policy enforcement points, some of which date back a number of years.“The challenge facing BT is around the size of the estate, the complexity and our ability to demonstrate at audit that the rules within the policy are still appropriate, still valid, and still authorized,” says Phil Packman, General Manager of Security Gateway Operations for BT. “Equally, we’re challenged to ensure that rules don’t make it into the rulebase unless they’re approved and authorized.” BT therefore realized that it needed automation and reporting to better control its massive rulebase, and provide an approved audit trail to both auditors and internal stakeholders. Solution BT set about to solve its security challenges by creating a set of criteria for evaluating off-the-shelf, automated security solutions. “The criteria were based on ‘total costof ownership,’ our roadmap, and probably most importantly, the willingness of the partner to work with us,” says Packman. AlgoSec uniquely met BT’s requirements.Another feature BT liked was AlgoSec’s ability to prove that policies are implemented as approved. According to Packman, this was a capability “which we’d not seen in other products, and which we couldn’t achieve with our in-house tools.”AlgoSec’s commitment to customer success and its money-back guarantee were also deciding factors in BT’s selection process. Results Immediately after deployment, AlgoSec enabled BT to reduce error rates, make improvements to their rulebase implementation process and ultimately give BT better control over its network security. Packman explains: “Most notably, we were able to track down rogue connectivity, or connectivity that we didn’t understand properly. It gave us an almost immediate view of certain high-risk situations.”In addition, by using AlgoSec’s compliance reports, Packman’s engineering team were able to instantly demonstrate that no rules could be added to the firewall policy without proper approval — saving countless hours.Simplifying the audit preparation process led to a surprise benefit for BT’s Security Gateway Operations Team, which performs rule implementation and authorization: “AlgoSec has allowed us to change the skills profile of the team because the tool does the heavy lifting for us. Now our engineers can focus more on providing greater levels of security than on process and change, so we’re able to provide a much more secure infrastructure for BT.”Packman also endorses AlgoSec’s customer service, stating that the relationship has been a very positive one. “This has really helped put our minds at rest. We believe we’ve done the right thing in terms of deploying AlgoSec.”Using AlgoSec continues to enable BT to manage the complexity of its network with confidence, as it pursues growing and competitive global markets for its IT, computing, and communications services. Packman summarizes: “We have met every objective we hoped to achieve with AlgoSec.” Schedule time with one of our experts

success stories "Using AlgoSec is a double benefit to us because we can reduce the cost and number of errors in our daily operation and also expand our offerings to our customers" Global Managed Services Company Optimizes Firewall Policies and Reduces Risks AlgoSec Business Impact • Improve security and assure compliance of its customers • Deliver comprehensive reports • Reduce costs and misconfiguration errors • Expand offerings to Arcon’s customers Background Founded in 1995, Arcon is the leading MSSP in Brazil. The company operates facilities in Rio de Janeiro, Sao Paulo, Brasília, Flórida, Salvador and Belém, managing the networks of many of Brazil’s top 100 companies, including banks, retailers, manufacturers and telecom companies. Arcon protectsmore than 600,000 users across five continents and processes more than one billion transactions each day. In addition to strategic management of IT security, Arcon protects data, servers, workstations and mobile devices and helps customers identify and control access to their systems. The company also evaluates risks in applications and provides technology infrastructure to support its customers’ businesses. Challenge Arcon provides security services to hundreds of other companies, including major retailers and banks, which require the tools that enable it to rapidly identify compliance issues and assess risks associated with network configurations. It must also be able to determine how to best optimize customers’ security policies and track changes made to firewall rules. With so many customers and service level agreements that require near immediate responses, Arcon needed visibility across the networks it manages and into reports allowing them to quickly find and fix issues and to counsel customers on changes that would improve their systems’ security. Solution Flavio Carvalho, the Security Management Services Director at Arcon, was charged with maintaining security across its own network, as well as diverse customers’ networks. Carvalho and his team selected the AlgoSec Security Management solution. “The combination of ease-of-use and the value add of AlgoSec’s reports, the ability to manage different technologies from multiple vendors, the cost per device managed, and the visibility across customer’s networks were key for us,” comments Carvalho.The quality of the AlgoSec’s reports clinched the deal. “With AlgoSec, we can quickly and easily provide PCI compliance reports to our customers, including banks and large retail stores. The excellent quality of the reports adds value to the services we manage for them,” says Carvalho. Results Arcon’s clients expect regular updates on the security of their networks — including recommendations for policy optimization, risk mitigation strategies, compliance verification and the impact of rule changes. “It would be impossible for us to deliver all of these in monthly reports without AlgoSec,” Carvalho notes. We have a big retail customer with SLAs of just one hour. “With AlgoSec we have been able to meet these SLAs much more easily than before. A report that previously took a day to generate can now be completed in a few minutes at the click of a button,” Carvalho notes.Shortly after implementation, Arcon’s experience with one large bank customer validated their decision to use AlgoSec — and made their customer very happy. “Our customer was under pressure because of high CPU utilization in their main firewall cluster,” explains Carvalho. “They needed us to investigate what was going on and to solve the issue as quickly and cost-effectively as possible. Using AlgoSec, we were able to easily identify a series of duplicate and poorly-written rules that were causing the trouble, and we solved the problem at no cost to the customer.”“Using AlgoSec is a double benefit to us because we can reduce the cost and number of errors in our daily operations and also expand our offerings to our customers,” adds Carvalho. “It’s easy to work with AlgoSec, as we have a direct contact and an excellent AlgoSec support team, which is always available to help us when necessary” concludes Carvalho.

Learn from expert-crafted firewall ruleset examples and best practices. Optimize your security posture with actionable guidance and improve your firewall configurations. Firewall ruleset examples & policy best practices Securing your network: guide to firewall rules examples Cyberattacks continue to rise globally as malicious actors tirelessly develop sophisticated tools and techniques to break through networks and security systems. With the digitalization of operations today and the increasing adoption of remote working, crucial business activities such as communication, data storage, and data transmission are now primarily done digitally. While this brings numerous advantages – allowing easy usability and scalability, enhancing collaboration, and reducing the risks of data loss – businesses have to deal with various security risks, such as data breaches and cyberattacks from hackers. Organizations must provide adequate network security to keep sensitive data safe and ensure their network is usable, trustworthy, and optimized for maximum productivity across all channels. Schedule a Demo Firewalls and your network Your network and systems (software and hardware) comprise the IT infrastructure through which you operate and manage your enterprise’s IT services. Every IT system regularly receives and transmits internet traffic, and businesses must ensure that only trusted and authorized traffic penetrates their network to maintain security. All unwanted traffic must be prevented from accessing your operating system as it poses a huge risk to network security. Malicious actors attempting to penetrate your system often send virus-carrying inbound traffic to your network. However, with an effective firewall, you can filter all traffic and block unwanted and harmful traffic from penetrating your network. A firewall serves as a barrier between computers, networks, and other systems in your IT landscape, preventing unauthorized traffic from penetrating. Schedule a Demo What are firewall rules? The firewall is your first line of defense in network security against hackers, malware, and other threats. Firewall rules refer to access control mechanisms that stipulate how a firewall device should handle incoming and outgoing traffic in your network. They are instructions given to firewalls to help them know when to block or allow communication in your network. These instructions include destination or source IP addresses, protocols, port numbers, and services. A firewall ruleset is formed from a set of rules and it defines a unit of execution and sharing for the rules. Firewall rulesets typically include: A source address A source port A destination address A destination port A decision on whether to block or permit network traffic meeting those address and port criteria Schedule a Demo What are the most common firewall ruleset examples? There are thousands of rulesets that can be used to control how a firewall deals with network traffic. Some firewall rules are more common than others, as they tend to be fundamental when building a secure network. Here are some examples of firewall rules for common use cases: Enable internet access for only one computer in the local network and block access for all others This rule gives only one computer in the local network access to the internet, and blocks all others from accessing the internet. This example requires obtaining the IP address of the computer being granted access (i.e., source IP address) and the TCP protocol type. Two rules will be created: a Permit rule and a Deny rule. The permit rule allows the chosen computer the required access, while the deny rule blocks all other computers in the local network from internet access. Prevent direct access from the public network to the firewall This rule blocks access to your firewall from any public network, to protect it from hackers who can modify or delete your rules if they access your firewall directly. Once hackers manipulate your rules, unwanted traffic will penetrate your network, leading to data breaches or an interruption in operation. A Deny rule for any attempt to access the firewall from public networks will be created and enabled. Block internet access for only one computer in the local network This rule comes in handy if you do not want a specific computer in the local network to access the internet. You will need to create a Deny rule in which you set the IP address of the computer you wish to block from the internet, and the TCP protocol type. Block access to a specific website from a local network In this scenario we want to configure our firewall to deny access to a particular website from a local network. We first obtain the IP address or addresses of the website we wish to deny access to, and then create a Deny rule. One way to obtain a website’s IP address is by running the special command ‘nslookup ’ in your operating system’s command line (Windows, Linux, or others). Since websites can run on HTTP and HTTPS, we must create a Deny rule for each protocol type and indicate the destination IP address(es). Thus, the local network will be unable to access both the HTTP and HTTPS versions of the website. Allow a particular LAN computer to access only one specific website This example gives a local computer access to only one specified website. We obtain the IP address of the destination website and the source IP address (of the local computer). We create a Permit rule for the source IP address and the destination website, and a Deny rule for the source IP address and other websites, taking the TCP protocol types into account. Allow internet access to and from the local network using specific protocols (services) only This example allows your LAN computer to access the internet using specific protocols, such as SMTP, FTP, IPv6, SSH, IPv4, POP3, DNS, and IMAP; and blocks all other traffic Here we first create an “Allow” rule for the “Home segment,” where we use the value “Any” for the Source and Destination IP addresses. In the Protocol field provided, we choose the protocols through which our local computer can access the internet. Lastly, we create Deny rules where we enter the value “Any” for the Source and Destination IP addresses. In the Protocol field, we set the values TCP and UDP, thus blocking internet access for unspecified protocols. Allow remote control of your router This rule enables you to access, view, or change your Router Settings remotely (over the internet). Typically, access to routers from the internet is blocked by default. To set this rule, you need specific data such as your router username, WAN IP address, and password. It is crucial to note that this setting is unsafe for individuals who use public IP addresses. A similar use case is a rule enabling users to check a device’s availability on their network by allowing ICMP ping requests. Block access from a defined internet subnet or an external network You can set a rule that blocks access to your network from a defined internet subnet or an external network. This rule is especially important if you observed repeated attempts to access your router from unknown IP addresses within the same subnet. In this case, set a Deny rule for IP addresses of the subnet attempting to access your WAN port. Schedule a Demo What are examples of best practices for setting up firewall rules? It is expedient to follow best practices during firewall configuration to protect your network from intruders and hackers. Deploying industry-standard rules when setting up firewalls can improve the security of your network and system components. Below are examples of the best practices for setting up firewall rules. Document firewall rules across multiple devices Documenting all firewall rule configurations and updating them frequently across various devices is one of the best practices for staying ahead of attacks. New rules should be included based on security needs, and irrelevant rules should be deactivated to reduce the possibility of a loophole in your network. With documentation, administrators can review the rules frequently and make any required changes whenever a vulnerability is detected. Configure your firewall to block traffic by default Using a block or deny-by-default policy is the safest way to deal with suspicious traffic. Enterprises must be sure that all types of traffic entering their network are identified and trusted to avoid security threats. In addition, whenever a vulnerability arises in the system, blocking by default helps prevent hackers from taking advantage of loopholes before administrators can respond. Monitor firewall logs Monitoring firewall logs on a regular basis helps maintain network security. Administrators can quickly and easily track traffic flow across your network, identify suspicious activity, and implement effective solutions in a timely manner. Organizations with highly sophisticated infrastructure can aggregate logs from routers, servers, switches, and other components to a centralized platform for monitoring. Group firewall rules to minimize complexity and enhance performance Depending on the complexity of your network, you may need thousands of rules to achieve effective network security. This complicates your firewall rules and can be a huge challenge for administrators. However, by grouping rules based on similar characteristics like protocols, TCP ports, IP addresses, etc., you simplify them and boost overall performance. Implement least-privileged access In any organization, employees have various roles and may require different data to execute their tasks efficiently. As part of network security practices, it’s important to ensure each employee’s access to the network is restricted to the minimum privileges needed to execute their tasks. Only users who require access to a particular service or resource should have it, thus preventing unnecessary exposure of data. This practice significantly minimizes the risk of intentional and accidental unauthorized access to sensitive data. Schedule a Demo How do firewall policies differ from a network security policy? A network security policy outlines the overall rules, principles, and procedures for maintaining security on a computer network. The policy sets out the basic architecture of an organization’s network security environment, including details of how the security policies are implemented. The overall objective of network security policy is to protect a computer network against internal and external threats. Firewall policies are a sub-group of network security policies, and refer to policies that relate specifically to firewalls. Firewall policies have to do with rules for how firewalls should handle inbound and outbound traffic to ensure that malicious actors do not penetrate the network. A firewall policy determines the types of traffic that should flow through your network based on your organization’s network and information security policies.
