Tags Share this article 11/15/21 Published In this guest blog, Jeff Yager from IT Central Station (soon to be PeerSpot), discusses how actual AlgoSec users have been able to securely accelerate their app delivery. These days, it is more important than ever for business owners, application owners, and information security professionals to speak the same language. That way, their organizations can deliver business applications more rapidly while achieving a heightened security posture. AlgoSec’s patented platform enables the world’s most complex organizations to gain visibility and process changes at zero-touch across the hybrid network. IT Central Station members discussed these benefits of AlgoSec , along with related issues, in their reviews on the site. Application Visibility AlgoSec allows users to discover, identify, map, and analyze business applications and security policies across their entire networks. For instance, Jacob S., an IT security analyst at a retailer, reported that the overall visibility that AlgoSec gives into his network security policies is high. He said, “It’s very clever in the logic it uses to provide insights, especially into risks and cleanup tasks . It’s very valuable. It saved a lot of hours on the cleanup tasks for sure. It has saved us days to weeks.” “AlgoSec absolutely provides us with full visibility into the risk involved in firewall change requests,” said Aaron Z. a senior network and security administrator at an insurance company that deals with patient health information that must be kept secure. He added, “There is a risk analysis piece of it that allows us to go in and run that risk analysis against it, figuring out what rules we need to be able to change, then make our environment a little more secure. This is incredibly important for compliance and security of our clients .” Also impressed with AlgoSec’s overall visibility into network security policies was Christopher W., a vice president – head of information security at a financial services firm, who said, “ What AlgoSec does is give me the ability to see everything about the firewall : its rules, configurations and usage patterns.” AlgoSec gives his team all the visibility they need to make sure they can keep the firewall tight. As he put it, “There is no perimeter anymore. We have to be very careful what we are letting in and out, and Firewall Analyzer helps us to do that.” For a cyber security architect at a tech services company, the platform helps him gain visibility into application connectivity flows. He remarked, “We have Splunk, so we need a firewall/security expert view on top of it. AlgoSec gives us that information and it’s a valuable contributor to our security environment.” Application Changes and Requesting Connectivity AlgoSec accelerates application delivery and security policy changes with intelligent application connectivity and change automation. A case in point is Vitas S., a lead infrastructure engineer at a financial services firm who appreciates the full visibility into the risk involved in firewall change requests. He said, “[AlgoSec] definitely allows us to drill down to the level where we can see the actual policy rule that’s affecting the risk ratings. If there are any changes in ratings, it’ll show you exactly how to determine what’s changed in the network that will affect it. It’s been very clear and intuitive.” A senior technical analyst at a maritime company has been equally pleased with the full visibility. He explained, “That feature is important to us because we’re a heavily risk-averse organization when it comes to IT control and changes. It allows us to verify, for the most part, that the controls that IT security is putting in place are being maintained and tracked at the security boundaries .” A financial services firm with more than 10 cluster firewalls deployed AlgoSec to check the compliance status of their devices and reduce the number of rules in each of the policies. According to Mustafa K. their network security engineer, “Now, we can easily track the changes in policies. With every change, AlgoSec automatically sends an email to the IT audit team. It increases our visibility of changes in every policy .” Speed and Automation The AlgoSec platform automates application connectivity and security policy across a hybrid network so clients can move quickly and stay secure. For Ilya K., a deputy information security department director at a computer software company, utilizing AlgoSec translates into an increase in security and accuracy of firewall rules. He said, “ AlgoSec ASMS brings a holistic view of network firewall policy and automates firewall security management in very large-sized environments. Additionally, it speeds up the changes in firewall rules with a vendor-agnostic approach.” “The user receives the information if his request is within the policies and can continue the request,” said Paulo A., a senior information technology security analyst at an integrator. He then noted, “Or, if it is denied, the applicant must adjust their request to stay within the policies. The time spent for this without AlgoSec is up to one week, whereas with AlgoSec, in a maximum of 15 minutes we have the request analyzed .” The results of this capability include greater security, a faster request process and the ability to automate the implementation of rules. Srdjan, a senior technical and integration designer at a large retailer, concurred when he said, “ By automating some parts of the work, business pressure is reduced since we now deliver much faster . I received feedback from our security department that their FCR approval process is now much easier. The network team is also now able to process FCRs much faster and with more accuracy.” To learn more about what IT Central Station members think about AlgoSec, visit https://www.itcentralstation.com/products/algosec-reviews Schedule a demo Related Articles Q1 at AlgoSec: What innovations and milestones defined our start to 2026?

Security Policy Management with Professor Wool Advanced Cyber Threat and Incident Management Advanced Cyber Threat and Incident Management is a whiteboard-style series of lessons that examine some of the challenges and provide technical tips for helping organizations detect and quickly respond to cyber-attacks while minimizing the impact on the business. Lesson 1 SIEM solutions collect and analyze logs generated by the technology infrastructure, security systems and business applications. The Security Operations Center (SOC) team uses this information to identify and flag suspicious activity for further investigation. In this lesson, Professor Wool explains why it’s important to connect the information collected by the SIEM with other databases that provide information on application connectivity, in order to make informed decisions on the level of risk to the business, and the steps the SOC needs to take to neutralize the attack. How to bring business context into incident response Watch Lesson 2 In this lesson Professor Wool discusses the need for reachability analysis in order to assess the severity of the threat and potential impact of an incident. Professor Wool explains how to use traffic simulations to map connectivity paths to/from compromised servers and to/from the internet. By mapping the potential lateral movement paths of an attacker across the network, the SOC team can, for example, proactively take action to prevent data exfiltration or block incoming communications with Command and Control servers.

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.

It is particularly well-suited to environments that require integration with other security tools. 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.
