What is the PRIMARY purpose for an organization to conduct a security audit?

Adhering to a defined standard describes a compliance assessment or regulatory audit, which is a subset of security activities, not the primary purpose of a security audit broadly defined.

The primary purpose of a security audit is to verify that security controls are properly implemented and functioning to mitigate identified risks. Audits assess the effectiveness of technical, administrative, and physical controls against known threats and vulnerabilities, ensuring the organization's risk posture is being actively managed and reduced.

Configuring information systems efficiently is an operational or IT management objective, not a security audit goal, as audits evaluate security posture rather than system performance or configuration efficiency.

Documenting findings is a byproduct and deliverable of the audit process, but it is not the primary purpose - documentation serves to communicate the results of the audit, not define its goal.
