ISO/IEC 27001:2022 A.8.18 — Use of privileged utility programs

What this control requires

The use of utility programs that can be capable of overriding system and application controls shall be restricted and tightly controlled.

In plain English

The use of utility programs that can be capable of overriding system and application controls shall be restricted and tightly controlled. In practice, this means you can prove you policy management-level controls on a defined cadence.

Why it matters

ISO 27001 certification depends on showing each Annex A control is either implemented or explicitly justified for exclusion in the Statement of Applicability (SoA). Certification bodies sample controls during surveillance audits, and a missing SoA entry — or implementation that doesn't match the SoA wording — is a finding.

This control is rated high. Auditors expect a named owner, a remediation SLA, and a tooling artefact that evidences continuous operation.

What an auditor looks for

An ISO 27001 lead auditor looks for: (1) an SoA entry covering the control with justification, (2) a documented procedure or policy implementing it, (3) records that prove the procedure runs (logs, tickets, training records) and (4) management-review evidence that effectiveness is monitored.

Within Technological controls, the assessor will trace your implementation back to the catalogue reference (Annex A A.8.18) and look for objective evidence on the latest two assessment cycles.

How to implement

Policy Management

Docs. Keep each policy in version-controlled Markdown alongside the code that implements it; ship a signed PDF snapshot at each annual review and link the SHA into the SoA.

Operational checklist

• Policy. Document the trigger, the owner and the cadence.
• Management. Document the trigger, the owner and the cadence.
• Access. Document the trigger, the owner and the cadence.
• Application. Document the trigger, the owner and the cadence.
• Change. Document the trigger, the owner and the cadence.
• Scope: management, utility.

Evidence to collect

• Infra Scan. Continuous infrastructure-posture telemetry — AWS Config, Azure Policy compliance, GCP Organisation Policy, Wiz / Prisma findings.
• Ticketing Workflow. ticketing_workflow evidence

Infrastructure compliance tooling (AWS Config, Azure Policy) and change-management workflows (ServiceNow, Jira) demonstrate restrictions on privileged utility programs.

Common pitfalls

• Policies that no engineer has read; the version in Confluence drifts from the version that's actually being enforced.

How it maps to other frameworks

Computed from shared tags, control component and key-operation subjects — handy when you are reconciling controls across an audit.
