ISO/IEC 27001:2022 and Penetration Testing
An information security management system (ISMS) standard for systematically managing risks to information, people, processes, and technology.
Using test evidence in an ISO/IEC 27001 management system
ISO/IEC 27001 is an information-security management-system standard. Testing is valuable when connected to scope, risk treatment, control owners, and management review.
- Define the ISMS scope and asset inventory before selecting systems to test so a narrow result is not presented as an organisation-wide risk conclusion.
- Select controls from risk assessment and the Statement of Applicability, not as a context-free checklist.
- Penetration testing is one way to evaluate technical-control effectiveness. The standard does not prescribe one fixed pentest cadence for every organisation.
- Record risks, findings, risk-acceptance decisions, remediation, and verification for internal audit and management review.
INFORMATION SECURITY MANAGEMENT
An information security management system (ISMS) standard for systematically managing risks to information, people, processes, and technology.
Requirements related to Penetration Testing
- ISO/IEC 27001:2022 does not require every organization to conduct Penetration Testing on a fixed schedule. It requires organizations to identify, assess, and treat information security risks systematically.
- Penetration Testing can provide a control activity and supporting evidence for Annex A 8.8 technical vulnerability management, A.8.29 security testing in development and acceptance, and A.5.35 independent review of information security.
- Scope and frequency should be based on risk assessment results, legal, regulatory, and contractual obligations, and system criticality.
- Test results should feed risk treatment, remediation, risk acceptance, and evidence of continual ISMS improvement.
Key point
ISO/IEC 27001 is a risk-based standard, not a test-case list. Penetration Testing should therefore be tied to each organization's risks and Statement of Applicability.
