ISO 27001 Risk Assessment & Statement of Applicability

Risk assessment and the Statement of Applicability are central to ISO/IEC 27001 because they determine how information security risks are evaluated, treated, and translated into justified control decisions. Organizations often understand what the standard requires but still need practical guidance on how to perform these activities consistently.

This publication focuses on the requirements for information security risk assessment, risk treatment, and development of the Statement of Applicability. It complements descriptive guidance in the ISO/IEC 27xxx family with a methodology developed through practical certification support experience.

For ISMS managers, consultants, auditors, and implementation teams, the book helps turn abstract requirements into a more usable approach for documenting risk decisions, selecting controls, and building evidence that supports ISO/IEC 27001 implementation and certification.
