How to perform a network audit?
A network audit entails collecting data, identifying threats and areas of weakness, and compiling a formal audit report. This report is then sent on to network administrators and other relevant parties. A network audit is usually performed by a network analyst, information system auditor, or another individual with a professional background in IT security and network management.
The following steps are typical of a comprehensive network audit.
Record the details of the audit
Document all procedures and processes associated with the audit
Review the procedure management system
Assess the training logs and operations
Confirm the security patches for network software are up-to-date
Confirm the penetration testing policy and process is sufficient
Test the software’s components as comprehensively as possible
Identify any firewall holes
Ensure all sensitive or confidential data is stored separately and securely
Encrypt the hard disks on any company laptops
Check the security of your wireless networks
Scan for and identify any unauthorized access points

Send the final report to appropriate stakeholders and other key parties
Important network audit parameters
Conducting a network audit is a crucial part of helping ensure the functionality and reliability of the enterprise network. If the network isn’t treated as a priority, it is likely to underperform—which will almost certainly result in unsatisfied customers. The following list guides you through the most important parameters of a network audit.
Keep in mind that while a network audit focuses on network security and management, it also reviews the measures and operations that impact network quality of service, network availability, and network performance.
