Last updated October 24th, 2023 by Avigdor Book

The importance of conducting a thorough network audit cannot be overstated. A thorough review of an organization’s network, its functionality, and security measures are the key elements of a network audit. The audit serves as an invaluable tool in identifying vulnerabilities, potential security risks, and areas for improvement in your network security policy.

What is Included in a Network Audit?

A network audit checklist typically includes the assessment of various components of a network. This includes examining firewall rules for any vulnerabilities and ensuring they are functioning optimally to protect you against cyber threats and unauthorized access. The audit also checks for the presence of malware in your operating systems and reviews the security of your access points.

Another essential part of the audit are wireless networks, which need to be rigorously checked for any security weaknesses as they are often a target for hackers. The audit will also assess the security of routers and other network devices, keeping an eye out for upgrades that need to be made or security patches that need to be applied.

How Do You Conduct a Network Audit?

Conducting a network audit starts with a comprehensive network audit checklist. This checklist will guide your security teams through the steps necessary for a robust audit, from reviewing your network infrastructure to penetration testing for vulnerabilities.

Checking for sensitive data, includes sensitive information stored on your network, as well as data transmitted through your network and is one of the most crucial steps in conducting an audit. Also worthwhile checking is your “bring your own device” (BYOD) policy, if you have one, and make sure all mobile devices and user accounts are secure.

The network audit checklist should also include a review of permissions and Internet access points to prevent unauthorized access. Implementing two-factor authentication can also enhance your security measures.

The Five Audit Checklist Components

When it comes to network audits, there are five key components to include in your checklist.

Functionality: Ensure your network is operating at optimal functionality, including bandwidth and network segment performance.
Security Measures: Review your network security policy, and implement necessary security protocols.
Vulnerabilities: Identify any vulnerabilities in your system, from potential cyberattacks to phishing threats.
Upgrade and Patch Management: Regularly update and patch your systems and devices to minimize security risks.
Audit Report: Compile an audit report that summarizes your findings and suggests improvements.

By following this in-depth checklist, you can enhance your network security and protect against potential security breaches.
