Tags Share this article 4/13/22 Published Prof. Avishai Wool, AlgoSec co-founder and CTO, stresses the importance of getting the often-overlooked function of managing network objects right, particularly in hybrid or multi-vendor environments Using network traffic filtering solutions from multiple vendors makes network object management much more challenging. Each vendor has its own management platform, which often forces network security admins to define objects multiple times, resulting in a counter effect. First and foremost, this can be an inefficient use of valuable resources from a workload bottlenecking perspective. Secondly, it creates a lack of naming consistency and introduces a myriad of unexpected errors, leading to security flaws and connectivity problems. This can be particularly applicable when a new change request is made. With these unique challenges at play, it begs the question: Are businesses doing enough to ensure their network objects are synchronized in both legacy and greenfield environments? What is network object management? At its most basic, the management of network objects refers to how we name and define “objects” within a network. These objects can be servers, IP addresses, or groups of simpler objects. Since these objects are subsequently used in network security policies, it is imperative to simultaneously apply a given rule to an object or object group. On its own, that’s a relatively straightforward method of organizing the security policy. But over time, as organizations reach scale, they often end up with large quantities of network objects in the tens of thousands, which typically lead to critical mistakes. Hybrid or multi-vendor networks Let’s take name duplication as an example. Duplication on its own is bad enough due to the wasted resource, but what’s worse is when two copies of the same name have two distinctly different definitions. Let’s say we have a group of database servers in Environment X containing three IP addresses. This group is allocated a name, say “DBs”. That name is then used to define a group of database servers in Environment Y containing only two IP addresses because someone forgot to add in the third. In this example, the security policy rule using the name DBs would look absolutely fine to even a well-trained eye, because the names and definitions it contained would seem identical. But the problem lies in what appears below the surface: one of these groups would only apply to two IP addresses rather than three. As in this case, minor discrepancies are commonplace and can quickly spiral into more significant security issues if not dealt with in the utmost time-sensitive manner. It’s important to remember that accuracy is the name in this game. If a business is 100% accurate in the way it handles network object management, then it has the potential to be 100% efficient. The Bottom Line The security and efficiency of hybrid multi-vendor environments depend on an organization’s digital hygiene and network housekeeping. The naming and management of network objects aren’t particularly glamorous tasks. Having said that, everything from compliance and automation to security and scalability will be far more seamless and risk averse if taken care of correctly.

Using Object Naming Conventions to Reduce Firewall Management Overhead Watch Lesson 4 In this lesson, Professor Wool examines some tips for including firewall rule recertification as part of your change management process, including questions you should be asking and be able to answer as well as guidance on how to effectively recertify firewall rules Tips for Firewall Rule Recertification Watch Lesson 5 In this lesson, Professor Wool examines how virtualization, outsourcing of data centers, worker mobility and the consumerization of IT have all played a role in dissolving the network perimeter and what you can do to regain control. Managing Firewall Policies in a Disappearing Network Perimeter Watch Lesson 6 In this lesson, Professor Wool examines some of the challenges when it comes to managing routers and access control lists (ACLs) and provides recommendations for including routers as part of your overall security policy with tips on change management, auditing and ACL optimization. Analyzing Routers as Part of Your Security Policy Watch Lesson 7 In this lesson, Professor Wool examines the complex challenges of accurately simulating network routing, specifically drilling into three options for extracting the routing information from your network: SNMP, SSH and HSRP or VRPP. Examining the Challenges of Accurately Simulating Network Routing Watch Lesson 8 In this lesson, Professor Wool examines the complex challenges of accurately simulating network routing, specifically drilling into three options for extracting the routing information from your network: SNMP, SSH and HSRP or VRPP. NAT Considerations When Managing Your Security Policy Watch Lesson 9 In this lesson, Professor Wool explains how you can create templates - using network objects - for different types of services and network access which are reused by many different servers in your data center. Using this technique will save you from writing new firewall rules each time you provision or change a server, reduce errors, and allow you to provision and expand your server estate more quickly. How to Structure Network Objects to Plan for Future Policy Growth Watch Lesson 10 In this lesson, Professor Wool examines the challenges of migrating business applications and physical data centers to a private cloud and offers tips to conduct these migrations without the risk of outages. Tips to Simplify Migrations to a Virtual Data Center Watch Lesson 11 In this lesson, Professor Wool provides the example of a virtualized private cloud which uses hypervisor technology to connect to the outside world via a firewall. If all worksloads within the private cloud share the same security requirements, this set up is adequate. But what happens if you want to run workloads with different security requirements within the cloud? Professor Wool explains the different options for filtering traffic within a private cloud, and discusses the challenges and solutions for managing them. Tips for Filtering Traffic within a Private Cloud Watch Lesson 12 In this lesson Professor Wool discusses ways to ensure that your security policy on your primary site and on your disaster recovery (DR) site are always sync. He presents multiple scenarios: where the DR and primary site use the exact same firewalls, where different vendor solutions or different models are used on the DR site, and where the IP address is or is not the same on the two sites. Managing Your Security Policy for Disaster Recovery Watch Lesson 13 In this lesson, Professor Wool highlights the challenges, benefits and trade-offs of utilizing zero-touch automation for security policy change management. He explains how, using conditional logic, its possible to significantly speed up security policy change management while maintaining control and ensuring accuracy throughout the process. Zero-Touch Change Management with Checks and Balances Watch Lesson 14 Many organizations have different types of firewalls from multiple vendors, which typically means there is no single source for naming and managing network objects. This ends up creating duplication, confusion, mistakes and network connectivity problems especially when a new change request is generated and you need to know which network object to refer to. In this lesson Profession Wool provides tips and best practices for how to synchronize network objects in a multi-vendor environment for both legacy scenarios, and greenfield scenarios. Synchronized Object Management in a Multi-Vendor Environment Watch Lesson 15 Many organizations have both a firewall management system as well as a CMDB, yet these systems do not communicate with each other and their data is not synchronized. This becomes a problem when making security policy change requests, and typically someone needs to manually translate the names used by in the firewall management system to the name in the CMDB, which is a slow and error-prone process, in order for the change request to work. In this lesson Professor Wool provides tips on how to use a network security policy management to coordinate between the two system, match the object names, and then automatically populate the change management process with the correct names and definitions. How to Synchronize Object Management with a CMDB Watch Lesson 16 Some companies use tools to automatically convert firewall rules from an old firewall, due to be retired, to a new firewall. In this lesson, Professor Wool explains why this process can be risky and provides some specific technical examples. He then presents a more realistic way to manage the firewall rule migration process that involves stages and checks and balances to ensure a smooth, secure transition to the new firewall that maintains secure connectivity. How to Take Control of a Firewall Migration Project Watch Lesson 17 PCI-DSS 3.2 regulation requirement 6.1 mandates that organizations establish a process for identifying security vulnerabilities on the servers that are within the scope of PCI. In this new lesson, Professor Wool explains how to address this requirement by presenting vulnerability data by both the servers and the by business processes that rely on each server. He discusses why this method is important and how it allows companies to achieve compliance while ensuring ongoing business operations. PCI – Linking Vulnerabilities to Business Applications Watch Lesson 18 Collaboration tools such as Slack provide a convenient way to have group discussions and complete collaborative business tasks. Now, these automated chatbots can be used for answering questions and handling tasks for development, IT and infosecurity teams. For example, enterprises can use chatbots to automate information-sharing across silos, such as between IT and application owners. So rather than having to call somebody and ask them “Is that system up? What happened to my security change request?” and so on, tracking helpdesk issues and the status of help requests can become much more accessible and responsive. Chatbots also make access to siloed resources more democratic and more widely available across the organization (subject, of course to the necessary access rights). In this video, Prof. Wool discusses how automated chatbots can be used to help a wide range of users for their security policy management tasks – thereby improving service to stakeholders and helping to accelerate security policy change processes across the enterprise.

What are firewall logs and why they are important Select a size Which network Can AlgoSec be used for continuous compliance monitoring? Yes, AlgoSec supports continuous compliance monitoring. As organizations adapt their security policies to meet emerging threats and address new vulnerabilities, they must constantly verify these changes against the compliance frameworks they subscribe to. AlgoSec can generate risk assessment reports and conduct internal audits on-demand, allowing compliance officers to monitor compliance performance in real-time. Security professionals can also use AlgoSec to preview and simulate proposed changes to the organization’s security policies. This gives compliance officers a valuable degree of lead-time before planned changes impact regulatory guidelines and allows for continuous real-time monitoring. What are firewall logs and why are they important? Network setups of the past consisted solely of servers in a server closet. Today, modern IT infrastructure consists of three main components: on-premises data centers, public clouds, and their connecting infrastructure. This new reality has created complex systems with multiple challenges. Regulations have become stricter, and organizations are under pressure to detect security threats fast. When faced with an issue, network security professionals must pinpoint the root cause, and to do that, they need evidence—which means investigating firewall logs. What is a firewall log? A firewall log is a record of the network connections (allowed and blocked) that a firewall inspects, capturing each event between your systems and the internet. Depending on the configuration, a firewall log may include all inspected traffic or only what the firewall allows to pass into the environment (what “gets past” the firewall). Each entry of a firewall log will specify the following data: Field Description Timestamp Exact date and time traffic was processed Action Decision made by the firewall (Allow, Deny, Drop) Rule ID Specific firewall rule that triggered the action Source IP & Port IP address and port from where traffic originated Destination IP & Port IP address and port that the traffic was trying to reach Protocol Network protocol used (TCP, UDP, ICMP) Bytes/Session Amount of data transferred during a session Zones Source and destination security zones (Trust, Untrust, DMZ) Beyond the question of “What is a firewall log?” there is also the question of where to store them. Organizations have a few options here. Firewall logs can: Stay on the firewall device Go to a basic syslog server for storage Undergo analysis via a security information and event management (SIEM) tool What is a firewall review? The process of reviewing a firewall is akin to a scheduled maintenance procedure that updates the rulebook of your firewall system. Things to be on the lookout for include: Duplicate rules Outdated server rules Overly broad rules that can lead to security vulnerabilities What is a firewall log review? Ready to play detective? Because a firewall log review requires just that. Analyzing firewall data is a continuous process of extracting relevant information from the firewall logs, i.e., the firewall’s own journal of events.. The key is to identify specific patterns that indicate security incidents, performance issues, or non-compliance events. This, in turn, requires centralizing logs with synchronized device clocks so that timelines line up (i.e., NTP across firewalls, servers, and your SIEM) and putting controls in place to preserve log integrity. How to interpret firewall logs in 6 steps So now that it is clear what a firewall log is—as well as how to store these logs and review them—the next step is knowing how to interpret them. Successfully extracting the necessary data from your firewall logs is a six-step process: Collect logs in one place: The central system needs to receive logs from all firewalls that extend from the data center to the cloud. Each entry missing from your logs allows malicious actors to remain unseen, i.e., pose an unknown threat.. Figure out what's normal: To detect abnormal behavior, you must first create a baseline for normal activity, i.e., typical traffic patterns. Hunt for suspicious patterns: The official investigation begins! What to flag? Network scanning activity from a single IP address that attempts to access multiple ports and internal devices and makes scheduled connections to unverified external servers (beaconing). Add context: Context turns raw events into decisions. Enrich IPs and ports from your logs with: Asset inventory: What system and business app is this? User directories: Who owns/uses it? Threat intelligence: Is the source/destination risky? This enrichment helps determine impact and priority—not just “who/what,” but whether the activity is expected, whether the system is critical, and how urgently you need to respond. Investigate and act: Trigger an incident response plan: Validate findings Contain the incident (isolate the host, block indicators at the firewall). Collect forensics (packet captures, memory snapshot, log preservation) Eradicate the threat Recover systems, operations, and data (patches, credential resets, rule updates) Notify stakeholders Document the case for post‑incident review. Measure and improve: Learn from your results. Identify rules that are creating too much noise and clean them up. Most importantly, track how long it takes you to respond to incidents you find in your logs. How does AlgoSec help with firewall logs?

Firewall Policy Management 12 Best Network Security Audit Tools + Key Features 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 Fortified network security requires getting a variety of systems and platforms to work together. Security teams need to scan for potential threats, look for new vulnerabilities in the network, and install software patches in order to keep these different parts working smoothly. While small organizations with dedicated cybersecurity teams may process these tasks manually at first, growing audit demands will quickly outpace their capabilities. Growing organizations and enterprises rely on automation to improve IT security auditing and make sure their tech stack is optimized to keep hackers out. Network Security Audit Tools Explained Network Security Audit Tools provide at-a-glance visibility into network security operations and infrastructure. They scan network security tools throughout the environment and alert administrators of situations that require their attention. These situations can be anything from emerging threats, newly discovered vulnerabilities, or newly released patches for important applications. Your network security audit tools provide a centralized solution for managing the effectiveness of your entire security tech stack – including cloud-based software solutions and on-premises tools alike. With such a wide set of responsibilities, it should come as no surprise that many audit tools differ widely from one another. Some are designed for easy patch management while others may focus on intrusion detection or sensitive data exfiltration. Major platforms and operating systems may even include their own built-in audit tools. Microsoft Windows has an audit tool that focuses exclusively on Active Directory. However, enterprise security teams don’t want to clutter their processes with overlapping tools and interfaces – they want to consolidate their auditing tools onto platforms that allow for easy management and oversight. Types of Network Security Audit Tools Firewall Auditing Tools Firewall security rules provide clear instructions to firewalls on what kind of traffic is permitted to pass through. Firewalls can only inspect connections they are configured to detect . These rules are not static , however. Since the cybersecurity threat landscape is constantly changing, firewall administrators must regularly update their policies to accommodate new types of threats. At the same time, threat actors who infiltrate firewall management solutions can gain a critical advantage over their targets. They can change the organization’s security policies to ignore whatever malicious traffic they are planning on using to compromise the network. If these changes go unnoticed, even the best security technologies won’t be able to detect or respond to the threat. Security teams must regularly evaluate their firewall security policies to make sure they are optimized for the organization’s current risk profile. This means assessing the organization’s firewall rules and determining whether it is meeting its security needs. The auditing process may reveal overlapping rules, unexpected configuration changes , or other issues. Vulnerability Scanners Vulnerability scanners are automated tools that create an inventory of all IT assets in the organization and scan those assets for weak points that attackers may exploit. They also gather operational details of those assets and use that information to create a comprehensive map of the network and its security risk profile. Even a small organization may have thousands of assets. Hardware desktop workstations, laptop computers, servers, physical firewalls, and printers all require vulnerability scanning. Software assets like applications , containers, virtual machines, and host-based firewalls must also be scanned. Large enterprises need scanning solutions capable of handling enormous workloads rapidly. These tools provide security teams with three key pieces of information: Weaknesses that hackers know how to exploit . Vulnerability scanners work based on known threats that attackers have exploited in the past. They show security teams exactly where hackers could strike, and how. The degree of risk associated with each weakness . Since scanners have comprehensive information about every asset in the network, they can also predict the damage that might stem from an attack. This allows security teams to focus on high-priority risks first. Recommendations on how to address each weakness . The best vulnerability scanners provide detailed reports with in-depth information on how to mitigate potential threats. This gives security personnel step-by-step information on how to improve the organization’s security posture. Penetration Testing Tools Penetration testing allows organizations to find out how resilient their assets and processes might be in the face of an active cyberattack. Penetration testers use the same tools and techniques hackers use to exploit their victims, showing organizations whether their security policies actually work. Traditionally, penetration testing is carried out by two teams of cybersecurity professionals. The “red team” attempts to infiltrate the network and access sensitive data while the “blue team” takes on defense. Cybersecurity professionals should know how to use the penetration testing tools employed by hackers and red team operatives. Most of these tools have legitimate uses and are a fixture of many IT professionals’ toolkits. Some examples include: Port scanners . These identify open ports on a particular system. This can help users identify the operating system and find out what applications are running on the network. Vulnerability scanners . These search for known vulnerabilities in applications, operating systems, and servers. Vulnerability reports help penetration testers identify the most reliable entry point into a protected network. Network analyzers . Also called network sniffers, these tools monitor the data traveling through the network. They can provide penetration testers with information about who is communicating over the network, and what protocols and ports they are using. These tools help security professionals run security audits by providing in-depth data on how specific attack attempts might play out. Additional tools like web proxies and password crackers can also play a role in penetration testing, providing insight into the organization’s resilience against known threats. Key Functionalities of Network Security Audit Software Comprehensive network security audit solutions should include the following features: Real-time Vulnerability Assessment Network Discovery and Assessment Network Scanning for Devices and IP Addresses Identifying Network Vulnerabilities Detecting Misconfigurations and Weaknesses Risk Management Customizable Firewall Audit Templates Endpoint Security Auditing Assessing Endpoint Security Posture User Account Permissions and Data Security Identifying Malware and Security Threats Compliance Auditing Generating Compliance Audit Reports Compliance Standards and Regulations PCI DSS HIPAA GDPR NIST Integration and Automation with IT Infrastructure Notifications and Remediation User Interface and Ease of Use Operating System and Configuration Auditing Auditing Windows and Linux Systems User Permissions and Access Control Top 12 Network Security Audit Tools 1.

Steps to Conduct a Network Security Audit Define the Scope : Start by defining the scope of your audit. You’ll need to determine which parts of your network and systems will be audited. Consider the goals and objectives of the audit, such as identifying vulnerabilities, ensuring compliance, or assessing overall security posture. Gather Information : Collect all relevant information about your network, including network diagrams, asset inventories, and existing security policies and procedures. This information will serve as a baseline for your audit. The more comprehensive this information is, the more accurate your audit results can be. Identify Assets : List all the assets on your network, including servers, routers, switches, firewalls, and endpoints. Ensure that you have a complete inventory of all devices and their configurations. If this information is not accurate, the audit may overlook important gaps in your security posture. Assess Vulnerabilities : Use network vulnerability scanning tools to identify vulnerabilities in your network. Vulnerability scanners like Nessus or OpenVAS can help pinpoint weaknesses in software, configurations, or missing patches. This process may take a long time if it’s not supported by automation. Penetration Testing : Conduct penetration testing to simulate cyberattacks and assess how well your network defenses hold up. Penetration testing tools like Metasploit or Burp Suite can help identify potential security gaps. Automation can help here, too – but the best penetration testing services emulate the way hackers work in the real world. Review Policies and Procedures : Evaluate the results of your vulnerability and penetration testing initiatives. Review your existing security policies and procedures to ensure they align with best practices and compliance requirements. Make necessary updates or improvements based on audit findings. Log Analysis : Analyze network logs to detect any suspicious or unauthorized activities. Log analysis tools like Splunk or ELK Stack can help by automating the process of converting log data into meaningful insights. Organizations equipped with SIEM platforms can analyze logs in near real-time and continuously monitor their networks for signs of unauthorized behavior. Review Access Controls : Ensure the organization’s access control policies are optimal. Review user permissions and authentication methods to prevent unauthorized access to critical resources. Look for policies and rules that drag down production by locking legitimate users out of files and folders they need to access. Firewall and Router Configuration Review: Examine firewall and router configurations to verify that they are correctly implemented and that access rules are up to date. Ensure that only necessary ports are open, and that the organization’s firewalls are configured to protect those ports. Prevent hackers from using port scanners or other tools to conduct reconnaissance. Patch Management : Check for missing patches and updates on all network devices and systems. Regularly update and patch software to address known vulnerabilities. Review recently patched systems to make sure they are still compatible with the tools and technologies they integrate with. Incident Response Plan : Review and update your incident response plan. Ensure the organization is prepared to respond effectively to security incidents, and can rely on up-to-date playbooks in the event of a breach. Compare incident response plans with the latest vulnerability scanning data and emerging threat intelligence information. Documentation and Reporting: Document all audit findings, vulnerabilities, and recommended remediation steps. Generate data visualizations that guide executives and other stakeholders through the security audit process and explain its results. Create a comprehensive report that includes an executive summary, technical details, and prioritized action items. Remediation : Implement the necessary changes and remediation measures to address the identified vulnerabilities and weaknesses. Deploy limited security resources effectively, prioritizing fixes based on their severity. Avoid unnecessary downtime when reconfiguring security tools and mitigating risk. Follow-Up Audits: Schedule regular follow-up audits to ensure that the identified vulnerabilities have been addressed and that security measures are continuously improved. Compare the performance metric data gathered through multiple audits and look for patterns emerging over time. Training and Awareness: Provide training and awareness programs for employees to enhance their understanding of security best practices and their role in maintaining network security. Keep employees well-informed about the latest threats and vulnerabilities they must look out for. FAQs What are some general best practices for network security auditing? Network security audits should take a close look at how the organization handles network configuration management over time. Instead of focusing only on how the organization’s current security controls are performing, analysts should look for patterns that predict how the organization will perform when new threats emerge in the near future. This might mean implementing real-time monitoring and measuring how long it takes for obsolete rules to get replaced. What is the ideal frequency for conducting network security audits? Network security audits should be conducted at least annually, with more frequent audits recommended for organizations with high-security requirements. Automated policy management platforms like AlgoSec can help organizations audit their security controls continuously. Are network security audit tools effective against zero-day vulnerabilities? Network security audit tools may not detect zero-day vulnerabilities immediately. However, they can still contribute by identifying other weaknesses that could be exploited in tandem with a zero-day vulnerability. They also provide information on how long it takes the organization to recognize new vulnerabilities once they are discovered. What should I look for when choosing a network security audit tool for my organization? Consider factors like the tool’s compatibility with your network infrastructure, reporting capabilities, support and updates, and its track record in identifying vulnerabilities relevant to your industry. Large enterprises highly value scalable tools that support automation. Can network security audit tools help with regulatory compliance? Yes, many audit tools offer compliance reporting features, helping organizations adhere to various industry and government regulations. Without an automated network security audit tool in place, many organizations would be unable to consistently demonstrate compliance. How long does it take to conduct a typical network security audit? The duration of an audit varies depending on the size and complexity of the network. A thorough audit can take anywhere from a few days to several weeks. Continuous auditing eliminates the need to disrupt daily operations when conducting audits, allowing security teams to constantly improve performance. What are the most common mistakes organizations make during network security audits? Common mistakes include neglecting to update audit tools regularly, failing to prioritize identified vulnerabilities, and not involving key stakeholders in the audit process. Overlooking critical assets like third-party user accounts can also lead to inaccurate audit results. What are some important capabilities needed for a Cloud-Based Security Audit? Cloud-based security audits can quickly generate valuable results by scanning the organization’s cloud-hosted IT assets for vulnerabilities and compliance violations. However, cloud-based audit software must be able to recognize and integrate third-party SaaS vendors and their infrastructure. Third-party tools and platforms can present serious security risks, and must be carefully inspected during the audit process. What is the role of Managed Service Providers (MSPs) in Network Security Auditing? MSPs can use audits to demonstrate the value of their services and show customers where improvement is needed. Since this improvement often involves the customer drawing additional resources from the MSP, comprehensive audits can improve the profitability of managed service contracts and deepen the connection between MSPs and their customers.

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 Firewall Analyzer (AFA) and AlgoSec FireFlow (AFF), two of the flagship products in the AlgoSec arsenal. AlgoSec Firewall Analyzer ensures security and compliance by providing visibility and analysis into complex network security policies. AlgoSec 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

Arcon Maintains Security Across Diverse Customer Networks With AlgoSec Organization ARCON Industry Financial Services Headquarters Rio de Janeiro, Brazil Download case study Share Customer
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.
