Framework Information Security & Privacy
ISO/IEC 27001:2022 is the international standard for an information security management system (ISMS).
It requires an organization to define the scope of its ISMS, assess information security risks, choose and justify controls from Annex A (93 controls in four themes: organizational, people, physical and technological), implement them, measure performance, audit itself and improve.
The 2022 edition replaced the 2013 edition; the IAF transition deadline was October 31, 2025, after which 2013 certificates are no longer valid. Amendment 1 (February 2024) added a requirement to consider whether climate change is a relevant issue for the ISMS.
Certification depends on documented information. The standard names the documents that must exist: ISMS scope, information security policy, risk assessment and risk treatment process and results, Statement of Applicability, security objectives, evidence of competence, operational planning records, monitoring results, internal audit program and results, management review outputs, and nonconformity and corrective action records.
Annex A adds topic-specific policies (access control, acceptable use, supplier security, secure development, backup, logging and more).
Voluntary. Adopted by organizations of any size or sector when customers, tenders or regulators ask for a certified ISMS. Some laws and sector schemes reference it as evidence of appropriate security, but certification itself is not legally mandated in most jurisdictions.
ISMS scope and context analysis; information security policy and topic-specific policies; risk assessment methodology, risk register and treatment plan; Statement of Applicability with justification for each Annex A control; asset inventory and ownership; roles and competence records; awareness training records; access control and supplier management records; incident records; business continuity and backup test results; monitoring and measurement results; internal audit reports; management review minutes; corrective action records.
Where the requirement sits: 5.2 policy; 7.3 awareness; 7.5 documented information; A.5.1 (2022) policies approved, communicated, acknowledged, reviewed; A.5.4; A.6.3 awareness; A.6.6 NDAs. Not covered: 6.1.2/6.1.3 risk + SoA
The 5.2 / 7.3 / 7.5 / A.5.1 policy layer of ISO 27001 - written, approved, communicated and acknowledged, with the audit trail.
