Build assurance conclusions from traceable evidence
Separate control design, implementation, operating evidence, assessment scope, findings, limitations and reviewer judgement so an assurance record does not overstate what the evidence proves.
Control effectiveness
A control-effectiveness decision should identify the control objective and scope, how the control is implemented, evidence that it operated during the relevant period, the assessment method and test population, exceptions and findings, inherited or dependent controls, limitations, reviewer judgement and required remediation. A policy, screenshot or configured setting by itself is rarely sufficient evidence of sustained effectiveness.
Open guide →Assurance guideEvidence quality
Strong assurance evidence has a known source and owner, clear scope and time period, preserved integrity or provenance, sufficient completeness for the decision, relevance to the control or risk claim, freshness appropriate to the subject, and a review trail that records limitations and contradictory evidence. Quantity of attachments is not evidence quality.
Open guide →Cyber Risk Decisions
Connect assurance evidence back to risk scenarios, treatment and residual-risk decisions.
