How Can You Improve the Process of Conducting Network Security Audits?

To help you conduct a thorough network security audit, we asked cybersecurity professionals for their best advice. From thinking like a hacker to creating an exhaustive inventory, here are the top four tips shared by a Managing Director, a Systems Administrator, and more.

• Think Like a Hacker
• Define Audit Goals Clearly
• Adopt a Comprehensive Approach
• Create an Exhaustive Inventory

Think Like a Hacker

The best advice for conducting a thorough network security audit is to 'think like a hacker, act like a guardian' to understand potential attackers' mindsets to uncover hidden vulnerabilities that traditional audits might miss.

Update your threat models regularly with the latest intelligence, incorporate Zero-Trust principles, and combine automated tools with manual checks for a comprehensive approach.

Having a good cybersecurity consultant on speed dial never hurts, either!

Define Audit Goals Clearly

Start by defining what you want to achieve and what parts of the network you'll focus on. This helps you stay organized and ensures you don't miss anything important. Gather all the necessary information, like network diagrams and past audit reports, so you have a clear picture of how everything fits together. This groundwork is essential for a thorough and effective audit.

In addition to having a plan, it's important to use both automated tools and hands-on techniques to find vulnerabilities. Automated tools can quickly spot common issues like outdated software or weak passwords. However, don't rely solely on them. Manual checks, like reviewing configurations and talking to staff, can reveal more subtle threats that automated tools might miss. Keeping up with the latest threats and using a mix of methods will make your network security audit more effective.

Adopt a Comprehensive Approach

A thorough network security audit is vital for identifying and mitigating potential vulnerabilities within your organization's network.

My primary piece of advice is to adopt a comprehensive approach that includes both automated tools and manual review processes. Start by mapping out all network assets to understand where your data resides and how it flows through your systems. Utilize vulnerability scanners to detect known security weaknesses, and supplement these tools with penetration testing to uncover less-obvious exploits.

It's crucial to review configurations for hardware and software to ensure they adhere to security best practices. Finally, involve your IT team and employees in regular training on the latest security threats and mitigation techniques to keep your defenses as robust as possible.

Create an Exhaustive Inventory

A thorough network security audit requires starting by creating an exhaustive inventory of all network assets, including hardware, software, and data. Prioritize risk assessment to identify and address vulnerabilities, and ensure regular updates and patches are applied. Conduct both automated and manual testing to cover all potential entry points. Lastly, document all findings meticulously and develop a robust incident-response plan to address any discovered threats. This helps set the right understanding for what is being covered, to what extent, and possible gaps that need to be monitored.
