Information Security, Cybersecurity and Privacy Protection — Guidance on Managing Information Security Risks
ISO/IEC 27005:2022 provides an end-to-end framework for managing information security risks aligned with ISO 31000 and ISO/IEC 27001. It elaborates methodologies for asset-threat-vulnerability identification, quantitative vs. qualitative impact estimation, residual risk treatment, and continuous risk monitoring in rapidly changing cloud and IT environments.
Scope & Applicability
Guidance applicable to all organizations that intend to manage risks that could compromise information security.
Non-Coverage Boundaries
Does not mandate a specific proprietary risk methodology (e.g. OCTAVE, FAIR), but provides the criteria against which any valid methodology must operate.
Key Clauses & Control Requirements
Information Security Risk Assessment
Identification of risk events, risk owners, consequences, and likelihood using threat-vulnerability relationships.
Information Security Risk Treatment
Selecting risk treatment options: modification (controls), retention (acceptance), avoidance, or sharing.
Required Regulatory & Audit Evidence Artifacts
- [✓]Information Security Risk Assessment Methodology Document
- [✓]Risk Register with quantified business impact and risk owners
- [✓]Formal Risk Acceptance memos signed by C-level executives
“A risk register is a live operational radar, not an annual compliance chore. Every accepted residual risk must have an accountable business executive owner.”
