What best describes "security auditing"?

The best description of "security auditing" is a method for assessing security compliance and identifying risks. Security auditing involves systematically reviewing and evaluating an organization's security policies, controls, and processes. The primary goal is to ensure that the organization adheres to established security standards, regulations, and internal policies. During a security audit, various components such as access controls, data protection measures, incident response plans, and overall security posture are examined to identify vulnerabilities and ensure compliance with regulatory requirements. This process helps organizations recognize risks that could lead to data breaches or cyber threats, enabling them to implement necessary improvements to their security measures.

The other options do not align with the core purpose of security auditing. Enhancing user experience, increasing system performance, and promoting business efficiency may be benefits of a well-secured system but are not the primary focus of security auditing. Instead, the emphasis is on assessing and improving security frameworks to proactively manage risks.
