Practical answer with owners, evidence, review triggers, and external source references. *FAQ* *Global* *ISO/IEC 27005* ## ISO/IEC 27005 FAQ Asset And Scenario Modeling Answer asset and scenario modeling questions with explicit owner, evidence, and escalation expectations for ISO/IEC 27005. Applied to this decision area, this page focuses on scope, ownership, evidence, review triggers, and escalation criteria supported by source-linked risk-management guidance. This FAQ explains the basics of asset and scenario modeling for ISO/IEC 27005. An asset is the thing you are trying to protect, such as information, a system, a service, or a business process. A scenario is the story of how a threat could affect that asset, so you can describe what might happen, who or what could be involved, and what harm could result. ## How should teams model assets and scenarios under ISO/IEC 27005 risk assessments? Start by naming the asset, the threat source, the relevant vulnerability or predisposing condition, and the expected impact. Then write the scenario as a short, testable statement that links those pieces together. For AI governance work, start from the AI system inventory: purpose, role, provider or deployer status, data inputs, impact assessment, control owner, monitoring signal, human oversight, and change trigger. This keeps the answer useful in audits, customer reviews, incidents, supplier reviews, and management review. - Name the accountable owner and reviewer for Asset And Scenario Modeling. - Record the scope, assumptions, decision, approval date, evidence location, exception status, and next review trigger. - Escalate when Asset And Scenario Modeling changes risk acceptance, service commitments, customer promises, regulatory duties, or certification evidence.

The evidence should show the process operating. For this artifact, the strongest record usually includes risk criteria, scenarios, likelihood and impact rationale, treatment decisions, residual-risk approvals, and review records. Avoid evidence that only repeats a requirement. A reviewer should be able to see the actual owner, date, system, supplier, AI system, service, incident, risk, or control sample behind the answer. - Use source records from the system of work, not screenshots created only for audit day. - Keep exceptions visible as risk acceptance, corrective action, or management-review input. - Update linked registers when the answer changes an owner, risk, control, service, supplier, or review date.

The person who can fund, operate, and correct the process should own the decision; governance should review consistency and exceptions. For high-impact changes, approval should include the teams affected by the evidence: security, privacy, resilience, supplier management, AI governance, legal, risk, or business service owners as relevant. - Use a named owner, named backup, and named escalation forum. - Separate preparation work from risk acceptance and final approval. - Keep approval records with the evidence rather than in disconnected email threads.

Review it at planned intervals and whenever the underlying scope, service, supplier, control, risk, AI system, personal data flow, incident process, or customer commitment changes. A stale record is worse than a short record. If the facts change, update the evidence and mark what changed so the next reviewer can trust the page. - Set a planned review date and a change-trigger rule. - Use findings to update controls, procedures, contracts, risk registers, or training. - Carry unresolved items into management review or risk acceptance.
