What is the purpose of a security audit?

The purpose of a security audit is fundamentally to evaluate the effectiveness of security measures. This process involves a systematic examination of an organization's security policies, procedures, and controls to identify strengths, weaknesses, and areas for improvement. Through this evaluation, organizations can assess whether their security measures are achieving the desired outcomes in protecting assets, ensuring compliance with regulations, and addressing potential vulnerabilities.

A security audit helps to provide a clear picture of the current security posture and is essential for making informed decisions on future enhancements or adjustments. It allows organizations to pinpoint specific areas where security may be lacking and where additional resources or changes may be necessary.

Other options like eliminating all risks, training personnel, or designing new equipment don’t encapsulate the core function of a security audit. While these may be important aspects of a comprehensive security program, they do not directly relate to the audit's goal of assessing and improving existing security measures.
