A.8.8·high·Component: Technological controlsWhat this control requires
Information about technical vulnerabilities of information systems in use shall be obtained, the organization's exposure to such vulnerabilities shall be evaluated and appropriate measures shall be taken.
In plain English
Information about technical vulnerabilities of information systems in use shall be obtained, the organization's exposure to such vulnerabilities shall be evaluated and appropriate measures shall be taken. In practice, this means you can prove you policy information-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.8.8) 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.
Vulnerability Management
Scanners. Pair an unauthenticated scanner (Nessus / Qualys / Tenable.io) for external surface with an authenticated agent for OS/library CVEs on every host.
SLA. Document remediation SLAs by CVSS / EPSS: critical 7 days, high 30 days, medium 90 days; report monthly trend to leadership.
Containers. Scan images in CI (Trivy / Grype / Snyk Container) AND at runtime; block deploys on critical findings without exception.
Operational checklist
- Policy. Document the trigger, the owner and the cadence.
- Information. Document the trigger, the owner and the cadence.
- Management. Document the trigger, the owner and the cadence.
- Scope: information, management.
Evidence to collect
- Infra Scan. Continuous infrastructure-posture telemetry — AWS Config, Azure Policy compliance, GCP Organisation Policy, Wiz / Prisma findings.
- Vapt Scan.
vapt_scanevidence
Vulnerability management scans (Qualys, Defender for Cloud) and penetration testing outputs document remediation of technical flaws.
Common pitfalls
- Policies that no engineer has read; the version in Confluence drifts from the version that's actually being enforced.
- Scans that hit only the perimeter; missing authenticated scans of OS, runtime libs and base images so most CVEs are invisible.
