The management system clauses of ISO 27001 that every certified organization must meet in full: context, leadership, planning, support, operation, performance evaluation and improvement, beyond the Annex A controls.
An overview of the mandatory ISO 27001 requirements: what each of clauses 4 to 10 covers, why none can be excluded, how they relate to the 93 Annex A controls and the Statement of Applicability, and which clauses auditors test at every visit.
How to meet ISO 27001 clauses 4.1 and 4.2: determining internal and external issues, the link to ISO 31000 context, the 2024 climate change amendment, identifying interested parties and their requirements, and how this feeds scope and risk assessment.
What ISO 27001 clause 5 asks of top management: leadership and commitment, the information security policy and assigned roles, how auditors test management involvement, governance guidance in ISO/IEC 27014, and why this cannot be handed to a consultant.
Setting ISO 27001 information security objectives under clause 6.2 and measuring them under clause 9.1: what to monitor and measure, ISO/IEC 27004 guidance and its revision, how NIST CSF 2.0 references clause 9.1, and the evidence auditors expect before certification.
How to evidence ISO 27001 competence under clause 7.2 and awareness under clause 7.3: how these differ from the A.6.3 training control, role-based training, resources under clause 7.1, and how NIS2 and NIST CSF reference the same requirements.
Which documents and records ISO 27001 requires and how to control them under clause 7.5: the Statement of Applicability, policies, documented operating procedures, risk and audit records, and keeping documented information versioned and access-controlled.
How to run the ISO 27001 management review under clause 9.3: required inputs and results, how it links to internal audit and corrective action, how often to hold it, how NIST CSF 2.0 references it, and what certification auditors look for in the minutes.
