Security Requirement
Security Requirement: A mandatory condition that a system, process, or control must satisfy for security purposes. It should be documented, assigned to an owner, measured, and reviewed at defined intervals.
How it works and where it fits
Security Requirement 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.
