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 and overall cybersecurity posture.
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 IT team and stakeholders through the steps necessary for a robust audit, from reviewing your network infrastructure to penetration tests and vulnerability scans that identify potential weaknesses in real time.
Checking for sensitive data, including sensitive information stored on your network as well as data transmitted through your network traffic, is one of the most crucial steps in conducting an audit. It is also worthwhile to check your “bring your own device” (BYOD) policy and make sure all laptops, 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 multi-factor authentication and strong access controls can further enhance your security measures.
The Five Audit Checklist Components
When it comes to network audits, there are five key components to include in your audit checklist:
- Functionality: Ensure your network is operating at optimal functionality, including bandwidth, segmentation, and network segment performance. Watch for bottlenecks or downtime that could disrupt operations.
- Security Measures: Review your network security policy and implement necessary security protocols, access controls, and authentication mechanisms.
- Vulnerabilities: Identify any vulnerabilities in your system, from potential cyberattacks, phishing attempts, ransomware, or misconfigurations to malware infections.
- Upgrade and Patch Management: Regularly update and patch your systems, operating systems, and devices to minimize security risks and ensure regulatory compliance with standards like HIPAA and GDPR.
- Audit Report: Compile an audit report that summarizes your findings, highlights potential vulnerabilities, and suggests improvements for risk management and regulatory requirements.
By following this in-depth checklist, you can enhance your organization’s security posture and protect against potential security breaches.

FAQs
What is a Network Security Audit Checklist?
A network security audit checklist is used by IT security teams to review their organization’s security measures. It includes reviewing firewall rules, wireless networks, routers, operating systems, and access points, as well as testing authentication, segmentation, and endpoint security. For more information, refer to our article on firewall auditing.
How often should you conduct a network audit?
The frequency of network audits depends on the size and complexity of your network infrastructure, as well as any regulatory requirements such as HIPAA or GDPR. However, most organizations should perform regular audits at least once a year, with vulnerability scans or penetration tests conducted more frequently to address real-time security risks. Discover more about this in our article on audit readiness.
What is the importance of a network audit?
Network audits are crucial to maintaining the security and functionality of your network. They help identify potential vulnerabilities, phishing threats, and malware infections, while ensuring regulatory compliance. Network audits also strengthen your security settings, confirm proper segmentation of internal networks, and safeguard sensitive information. For more insights, please read our blog about network cybersecurity regulatory compliance.
What should be included in a network audit report?
An audit report should summarize audit checklist findings, highlight misconfigurations and potential vulnerabilities, and provide recommendations for patch management, access controls, and security protocols. It also acts as evidence of compliance with regulatory requirements and provides stakeholders with a roadmap for improving the organization’s security posture.
How do permissions and user access factor into an audit?
Permissions and user access reviews are essential to ensure that only authorized users have access to sensitive data, systems, and applications. By applying the principle of least privilege, implementing access controls, and monitoring user permissions, organizations can reduce insider threats, privilege creep, and security incidents.
What tools help automate network audit checklists?
Automation tools like Tufin simplify network management by automatically scanning firewall rules, checking for misconfigurations, and generating audit reports. This reduces manual effort, streamlines compliance checks, and helps identify vulnerabilities across endpoints, internal networks, and cloud environments in real time.
