Audit Evidence

Audit Evidence: Documented information used to demonstrate that a requirement or control is implemented and effective. It should be documented, assigned to an owner, measured, and reviewed at defined intervals.

How it works and where it fits

Audit Evidence creates a traceable framework for security decisions. Scope, assumptions, evaluation criteria, responsibilities, and expected outcomes are made explicit. It is therefore more than documentation: it connects business objectives and protection needs to concrete controls, accepted residual risks, and verifiable evidence.

Practical security relevance

Effectiveness requires an accountable owner, periodic review, and measurable criteria. Decisions should use current data, while exceptions record rationale, duration, and compensating measures. Audits and metrics should test not only whether a requirement formally exists, but whether it is applied in daily work and actually reduces the intended risk.
