Tags Share this article 8/30/21 Published In this guest blog, Jeff Yager from IT Central Station describes how AlgoSec is perceived by real users and shares how the solution meets their expectations for visibility and monitoring. Business-driven visibility A network and security engineer at a comms service provider agreed, saying, “ The complete and end-to-end visibility and analysis [AlgoSec] provides of the policy rule base is invaluable and saves countless time and effort .” On a related front, according to Srdjan, a senior technical and integration designer at a major retailer, AlgoSec provides a much easier way to process first call resolutions (FCRs) and get visibility into traffic. He said, “With previous vendors, we had to guess what was going on with our traffic and we were not able to act accordingly. Now, we have all sorts of analyses and reports. This makes our decision process, firewall cleanup, and troubleshooting much easier.” Organizations large and small find it imperative to align security with their business processes. AlgoSec provides unified visibility of security across public clouds, software-defined and on-premises networks, including business applications and their connectivity flows. For Mark G., an IT security manager at a sports company, the solution handles rule-based analysis . He said, “AlgoSec provides great unified visibility into all policy packages in one place. We are tracking insecure changes and getting better visibility into network security environment – either on-prem, cloud or mixed.” Notifications are what stood out to Mustafa K., a network security engineer at a financial services firm. He is now easily able to track changes in policies with AlgoSec , noting that “with every change, it automatically sends an email to the IT audit team and increases our visibility of changes in every policy.” Security policy and network analysis AlgoSec’s Firewall Analyzer delivers visibility and analysis of security policies, and enables users to discover, identify, and map business applications across their entire hybrid network by instantly visualizing the entire security topology – in the cloud, on-premises, and everything in between. “It is definitely helpful to see the details of duplicate rules on the firewall,” said Shubham S., a senior technical consultant at a tech services company. He gets a lot of visibility from Firewall Analyzer. As he explained, “ It can define the connectivity and routing . The solution provides us with full visibility into the risk involved in firewall change requests.” A user at a retailer with more than 500 firewalls required automation and reported that “ this was the best product in terms of the flexibility and visibility that we needed to manage [the firewalls] across different regions . We can modify policy according to our maintenance schedule and time zones.” A network & collaboration engineer at a financial services firm likewise added that “ we now have more visibility into our firewall and security environment using a single pane of glass. We have a better audit of what our network and security engineers are doing on each device and are now able to see how much we are compliant with our baseline.” Arieh S., a director of information security operations at a multinational manufacturing company, also used Tufin, but prefers AlgoSec, which “ provides us better visibility for high-risk firewall rules and ease of use.” “If you are looking for a tool that will provide you clear visibility into all the changes in your network and help people prepare well with compliance, then AlgoSec is the tool for you,” stated Miracle C., a security analyst at a security firm. He added, “Don’t think twice; AlgoSec is the tool for any company that wants clear analysis into their network and policy management.” Monitoring and alerts Other IT Central Station members enjoy AlgoSec’s monitoring and alerts features. Sulochana E., a senior systems engineer at an IT firm, said, “ [AlgoSec] provides real-time monitoring , or at least close to real time. I think that is important. I also like its way of organizing. It is pretty clear. I also like their reporting structure – the way we can use AlgoSec to clear a rule base, like covering and hiding rules.” For example, if one of his customers is concerned about different standards , like ISO or PZI levels, they can all do the same compliance from AlgoSec. He added, “We can even track the change monitoring and mitigate their risks with it. You can customize the workflows based on their environment. I find those features interesting in AlgoSec.” AlgoSec helps in terms of firewall monitoring. That was the use case that mattered for Alberto S., a senior networking engineer at a manufacturing company. He said, “ Automatic alerts are sent to the security team so we can react quicker in case something goes wrong or a threat is detected going through the firewall. This is made possible using the simple reports.” Sulochana E. concluded by adding that “AlgoSec has helped to simplify the job of security engineers because you can always monitor your risks and know that your particular configurations are up-to-date, so it reduces the effort of the security engineers.” To learn more about what IT Central Station members think about AlgoSec, visit our reviews page .

success stories "Today, we are many times more efficient and secure thanks to AlgoSec." Background The company’s globally distributed network includes more than ten demilitarized zones (DMZs) with 20 billion events processed per month across the multiple company locations. Firewalls play a vital role in protecting intellectual property at the perimeter level. Every firewall event is logged and processed. Challenges The company’s operations require a very large and diverse network with a large Global Network Security operations team that is spread across the US, EMEA and Asia. The team is responsible for the management of all perimeter and internal security solutions, remote access solutions, customer connectivity solutions and the Security Operations Center (SOC). “We suffered from a lot of network security issues that prevented us from running at the speed of the business,” declared the Senior Manager of Global Security and SOC. Auditing Firewall rules was a long, tedious and painful process Access revocation was performed using a manual reminders process The diverse army of firewalls across the network estate resulted in a non-standard way of making and executing Firewall change requests, requiring many steps to complete the process An out-of-the-box ServiceNow workflow with limited functionality couldn’t keep up Limited reporting capabilities relied on manual data processing There was no way to track performance of SLAs The cumbersome approval process required managers to login to the company ticketing portal Notification of unauthorized or unapproved changes on firewalls was clumsy and slow The company decided to acquire an orchestration and automation solution that could identify and mitigate risky firewall rules. Since the company is subject to many industry and legal regulations, the solution would have to automate compliance reporting as well as ensure accountability for all firewall changes. The solution also would have to integrate into existing ticketing processes and workflows while enabling the company, at its own pace, to advance to more and more automation. Solution The company evaluated several solutions by reviewing their features carefully and putting the best among them to the test in parallel proof of concept projects. The senior manager recalls, “We had a very close look at the leading solutions in the Network Security Policy Management space. One of them definitely stood out from the pack as the superior solution.” The company chose AlgoSec Horizon Security Analyzer (AFA) and AlgoSec Horizon FireFlow (AFF), two of the flagship products in the AlgoSec arsenal. 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. Results In short order, the company was able to capitalize on the significant advantages of the AlgoSec solution. “It was easy to customize the AlgoSec solution to fit into our environment and enhance it,” continued the senior manager. “But it didn’t take long before we were using the power of the two products to help us adopt better practices for lower risk, higher security, and better efficiency of our team.” Today, the AlgoSec solution is delivering significant improvements to the company’s security processes such as: Visibility across the entire network with an easy-to-use-and-understand executive dashboard Integration with the ticketing tool Proactive analysis of change requests to ensure compliance risk mitigation Prevention of unauthorized changes Elimination of human errors and associated application outages Automatic discovery and mapping of application-connectivity flows Single Sign On (SSO) integration that eliminated static user passwords Support for mobile firewall change-request manager approval “We are a big company with an enormous volume of network-security activity,” stated the manager. “In addition to the superior capabilities of the solution, we greatly appreciated the excellent customization opportunities that AlgoSec’s Professional Services were able to help us with. Today, we are many times more efficient and secure thanks to AlgoSec.” Schedule time with one of our experts

Firewall Change Management 5 Types of Firewalls for Enhanced Network Security Asher Benbenisty 2 min read Asher Benbenisty 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 10/25/23 Published Firewalls form the first line of defense against intrusive hackers trying to infiltrate internal networks and steal sensitive data. They act as a barrier between networks, clearly defining the perimeters of each. The earliest generation of packet-filter firewalls were rudimentary compared to today’s next-generation firewalls, but cybercrime threats were also less sophisticated. Since then, cybersecurity vendors have added new security features to firewalls in response to emerging cyber threats. Today, organizations can choose between many different types of firewalls designed for a wide variety of purposes. Optimizing your organization’s firewall implementation requires understanding the differences between firewalls and the network layers they protect. How Do Firewalls Work? Firewalls protect networks by inspecting data packets as they travel from one place to another. These packets are organized according to the transmission control protocol/internet protocol (TCP/IP), which provides a standard way to organize data in transit. This protocol is a concise version of the more general OSI model commonly used to describe computer networks. These frameworks allow firewalls to interpret incoming traffic according to strictly defined standards. Security experts use these standards to create rules that tell firewalls what to do when they detect unusual traffic. The OSI model has seven layers: Application Presentation Session Transport Network Data link Physical Most of the traffic that reaches your firewall will use one of the three major Transport layer protocols in this model, TCP, UDP, or ICMP. Many security experts focus on TCP rules because this protocol uses a three-step TCP handshake to provide a reliable two-way connection. The earliest firewalls only operated on the Network Layer, which provides information about source and destination IP addresses, protocols, and port numbers. Later firewalls added Transport Layer and Application Layer functionality. The latest next-generation firewalls go even further, allowing organizations to enforce identity-based policies directly from the firewall. Related Read : Host-Based vs. Network-Based Firewalls 1. Traditional Firewalls Packet Filtering Firewalls Packet-filtering firewalls only examine Network Layer data, filtering out traffic according to the network address, the protocol used, or source and destination port data. Because they do not inspect the connection state of individual data packets, they are also called stateless firewalls. These firewalls are simple and they don’t support advanced inspection features. However, they offer low latency and high throughput, making them ideal for certain low-cost inline security applications. Stateful Inspection Firewalls When stateful firewalls inspect data packets, they capture details about active sessions and connection states. Recording this data provides visibility into the Transport layer and allows the firewall to make more complex decisions. For example, a stateful firewall can mitigate a denial-of-service attack by comparing a spike in incoming traffic against rules for making new connections – stateless firewalls don’t have a historical record of connections to look up. These firewalls are also called dynamic packet-filtering firewalls. They are generally more secure than stateless firewalls but may introduce latency because it takes time to inspect every data packet traveling through the network. Circuit-Level Gateways Circuit-level gateways act as a proxy between two devices attempting to connect with one another. These firewalls work on the Session layer of the OSI model, performing the TCP handshake on behalf of a protected internal server. This effectively hides valuable information about the internal host, preventing attackers from conducting reconnaissance into potential targets. Instead of inspecting individual data packets, these firewalls translate internal IP addresses to registered Network Address Translation (NAT) addresses. NAT rules allow organizations to protect servers and endpoints by preventing their internal IP address from being public knowledge. 2. Next-Generation Firewalls (NGFWs) Traditional firewalls only address threats from a few layers in the OSI model. Advanced threats can bypass these Network and Transport Layer protections to attack web applications directly. To address these threats, firewalls must be able to analyze individual users, devices, and data assets as they travel through complex enterprise networks. Next-generation firewalls achieve this by looking beyond the port and protocol data of individual packets and sessions. This grants visibility into sophisticated threats that simpler firewalls would overlook. For example, a traditional firewall may block traffic from an IP address known for conducting denial-of-service attacks. Hackers can bypass this by continuously changing IP addresses to confuse and overload the firewall, which may allow routing malicious traffic to vulnerable assets. A next-generation firewall may notice that all this incoming traffic carries the same malicious content. It may act as a TCP proxy and limit the number of new connections made per second. When illegitimate connections fail the TCP handshake, it can simply drop them without causing the organization’s internal systems to overload. This is just one example of what next-gen firewalls are capable of. Most modern firewall products combine a wide variety of technologies to provide comprehensive perimeter security against comprehensive cyber attacks. How do NGFWs Enhance Network Security? Deep Packet Inspection (DPI) : NGFWs go beyond basic packet filtering by inspecting the content of data packets. They analyze the actual data payload and not just header information. This allows them to identify and block threats within the packet content, such as malware, viruses, and suspicious patterns. Application-Level Control : NGFWs can identify and control applications and services running on the network. This enables administrators to define and enforce policies based on specific applications, rather than just port numbers. For example, you can allow or deny access to social media sites or file-sharing applications. Intrusion Prevention Systems (IPS) : NGFWs often incorporate intrusion prevention capabilities. They can detect and prevent known and emerging cyber threats by comparing network traffic patterns against a database of known attack signatures. This proactive approach helps protect against various cyberattacks. Advanced Threat Detection: NGFWs use behavioral analysis and heuristics to detect and block unknown or zero-day threats. By monitoring network traffic for anomalies, they can identify suspicious behavior and take action to mitigate potential threats. U ser and Device Identification : NGFWs can associate network traffic with specific users or devices, even in complex network environments. This user/device awareness allows for more granular security policies and helps in tracking and responding to security incidents effectively. Integration with Security Ecosystem : NGFWs often integrate with other security solutions, such as antivirus software, intrusion detection systems (IDS), and security information and event management (SIEM) systems. This collaborative approach provides a multi-layered defense strategy . Security Automation : NGFWs can automate threat response and mitigation. For example, they can isolate compromised devices from the network or initiate other predefined actions to contain threats swiftly. In a multi-layered security environment, these firewalls often enforce the policies established by security orchestration, automation, and response (SOAR) platforms. Content Filtering : NGFWs can filter web content, providing URL filtering and content categorization. This helps organizations enforce internet usage policies and block access to potentially harmful or inappropriate websites. Some NGFWs can even detect outgoing user credentials (like an employee’s Microsoft account password) and prevent that content from leaving the network. VPN and Secure Remote Access : NGFWs often include VPN capabilities to secure remote connections. This is crucial for ensuring the security of remote workers and branch offices. Advanced firewalls may also be able to identify malicious patterns in external VPN traffic, protecting organizations from threat actors hiding behind encrypted VPN providers. Cloud-Based Threat Intelligence : Many NGFWs leverage cloud-based threat intelligence services to stay updated with the latest threat information. This real-time threat intelligence helps NGFWs identify and block emerging threats more effectively. Scalability and Performance : NGFWs are designed to handle the increasing volume of network traffic in modern networks. They offer improved performance and scalability, ensuring that security does not compromise network speed. Logging and Reporting : NGFWs generate detailed logs and reports of network activity. These logs are valuable for auditing, compliance, and forensic analysis, helping organizations understand and respond to security incidents. 3. Proxy Firewalls Proxy firewalls are also called application-level gateways or gateway firewalls. They define which applications a network can support, increasing security but demanding continuous attention to maintain network functionality and efficiency. Proxy firewalls provide a single point of access allowing organizations to assess the threat posed by the applications they use. It conducts deep packet inspection and uses proxy-based architecture to mitigate the risk of Application Layer attacks. Many organizations use proxy servers to segment the parts of their network most likely to come under attack. Proxy firewalls can monitor the core internet protocols these servers use against every application they support. The proxy firewall centralizes application activity into a single server and provides visibility into each data packet processed. This allows the organization to maintain a high level of security on servers that make tempting cyberattack targets. However, these servers won’t be able to support new applications without additional firewall configuration. These types of firewalls work well in highly segmented networks that allow organizations to restrict access to sensitive data without impacting usability and production. 4. Hardware Firewalls Hardware firewalls are physical devices that secure the flow of traffic between devices in a network. Before cloud computing became prevalent, most firewalls were physical hardware devices. Now, organizations can choose to secure on-premises network infrastructure using hardware firewalls that manage the connections between routers, switches, and individual devices. While the initial cost of acquiring and configuring a hardware firewall can be high, the ongoing overhead costs are smaller than what software firewall vendors charge (often an annual license fee). This pricing structure makes it difficult for growing organizations to rely entirely on hardware devices. There is always a chance that you end up paying for equipment you don’t end up using at full capacity. Hardware firewalls offer a few advantages over software firewalls: They avoid using network resources that could otherwise go to value-generating tasks. They may end up costing less over time than a continuously renewed software firewall subscription fee. Centralized logging and monitoring can make hardware firewalls easier to manage than complex software-based deployments. 5. Software Firewalls Many firewall vendors provide virtualized versions of their products as software. They typically charge an annual licensing fee for their firewall-as-a-service product, which runs on any suitably provisioned server or device. Some software firewall configurations require the software to be installed on every computer in the network, which can increase the complexity of deployment and maintenance over time. If firewall administrators forget to update a single device, it may become a security vulnerability. At the same time, these firewalls don’t have their own operating systems or dedicated system resources available. They must draw computing power and memory from the devices they are installed on. This leaves less power available for mission-critical tasks. However, software firewalls carry a few advantages compared to hardware firewalls: The initial subscription-based cost is much lower, and many vendors offer a price structure that ensures you don’t pay for resources you don’t use. Software firewalls do not take up any physical space, making them ideal for smaller organizations. The process of deploying software firewalls often only takes a few clicks. With hardware firewalls, the process can involve complex wiring and time-consuming testing. Advanced Threats and Firewall Solutions Most firewalls are well-equipped to block simple threats, but advanced threats can still cause problems. There are many different types of advanced threats designed to bypass standard firewall policies. Advanced Persistent Threats (APTs) often compromise high-level user accounts and slowly spread throughout the network using lateral movement. They may move slowly, gathering information and account credentials over weeks or months before exfiltrating the data undetected. By moving slowly, these threats avoid triggering firewall rules. Credential-based attacks bypass simple firewall rules by using genuine user credentials to carry out attacks. Since most firewall policies trust authenticated users, attackers can easily bypass rules by stealing user account credentials. Simple firewalls can’t distinguish between normal traffic and malicious traffic by an authenticated, signed-in user. Malicious insiders can be incredibly difficult to detect. These are genuine, authenticated users who have decided to act against the organization’s interest. They may already know how the firewall system works, or have privileged access to firewall configurations and policies. Combination attacks may target multiple security layers with separate, independent attacks. For example, your cloud-based firewalls may face a Distributed Denial of Service (DDoS) attack while a malicious insider exfiltrates information from the cloud. These tactics allow hackers to coordinate attacks and cover their tracks. Only next-generation firewalls have security features that can address these types of attack. Anti-data exfiltration tools may prevent users from sending their login credentials to unsecured destinations, or prevent large-scale data exfiltration altogether. Identity-based policies may block authenticated users from accessing assets they do not routinely use. Firewall Configuration and Security Policies The success of any firewall implementation is determined by the quality of its security rules. These rules decide which types of traffic the firewall will allow to pass, and what traffic it will block. In a modern network environment, this is done using four basic types of firewall rules: Access Control Lists (ACLs). These identify the users who have permission to access a certain resource or asset. They may also dictate which operations are allowed on that resource or asset. Network Address Translation (NAT) rules. These rules protect internal devices by hiding their original IP address from the public Internet. This makes it harder for hackers to gain unauthorized access to system resources because they can’t easily target individual devices from outside the network. Stateful packet filtering . This is the process of inspecting data packets in each connection and determining what to do with data flows that do not appear genuine. Stateful firewalls keep track of existing connections, allowing them to verify the authentication of incoming data that claims to be part of an already established connection. Application-level gateways. These firewall rules provide application-level protection, preventing hackers from disguising malicious traffic as data from (or for) an application. To perform this kind of inspection, the firewall must know what normal traffic looks like for each application on the network, and be able to match incoming traffic with those applications. Network Performance and Firewalls Firewalls can impact network performance and introduce latency into networks. Optimizing network performance with firewalls is a major challenge in any firewall implementation project. Firewall experts use a few different approaches to reduce latency and maintain fast, reliable network performance: Installing hardware firewalls on high-volume routes helps, since separate physical devices won’t draw computing resources away from other network devices. Using software firewalls in low-volume situations where flexibility is important. Sometimes, being able to quickly configure firewall rules to adapt to changing business conditions can make a major difference in overall network performance. Configuring servers to efficiently block unwanted traffic is a continuous process. Server administrators should avoid overloading firewalls with denied outbound requests that strain firewalls at the network perimeter. Firewall administrators should try to distribute unwanted traffic across multiple firewalls and routers instead of allowing it to concentrate on one or two devices. They should also try reducing the complexity of the firewall rule base and minimize overlapping rules.
