Episode 27 — A.5.9–5.10 — Asset inventory; Acceptable use
A.5.9 requires an accurate, current inventory of information and other associated assets, including hardware, software, data sets, cloud resources, identities, and services. For exam purposes, stress that inventories must identify owners, classification, location, and lifecycle state so that risks and controls can be applied consistently. In modern environments, “asset” extends beyond physical devices to ephemeral instances, containers, SaaS applications, and machine identities. A.5.10 complements inventory with acceptable use rules that define expected behavior for users and administrators, clarifying boundaries for personal use, data handling, tool installation, and monitoring consent. Together, these controls establish what the organization protects and how people are permitted to interact with those assets.
In practice, strong inventories integrate multiple discovery sources—CMDB, EDR, cloud APIs, identity providers, and software catalogs—to reconcile truth across environments. Automations tag assets with owners and classifications, trigger onboarding checklists, and enforce guardrails like MFA and posture checks. Acceptable use policies are acknowledged at hire and renewed regularly, with targeted variants for privileged users, contractors, and BYOD scenarios. Common failure modes include stale ownership, blind spots in shadow IT, and policy text that is vague or unenforced. Effective programs track inventory completeness, orphaned assets, and policy attestation rates; link violations to corrective training; and ensure disciplinary procedures are proportionate and documented. Candidates should connect these controls to downstream processes: vulnerability management depends on inventory fidelity, DLP relies on classification, and investigations rely on clear behavioral expectations to adjudicate misuse consistently.
