ISO 27001:2022 5.15: Access control
ISO 27001:2022 5.15 covers Access control. The held text names 5 evidence records for it, the first being Statement of Applicability entry for control A.5.15, showing inclusion or justified exclusion, implementation status and the risks it.... The common gap an assessor flags is The access control policy exists but is not reflected in actual system configurations.
Rules that govern both physical entry and logical access to information and associated assets are to be set and applied on the basis of business and information security requirements. Purpose (stated in ISO/IEC 27002:2022): ensures access to information and associated assets is authorized and unauthorized access is prevented. As an Annex A reference control, it is compared with the controls determined in risk treatment (6.1.3 c) and recorded in the Statement of Applicability as included or excluded, with the justification and implementation status (6.1.3 d); implementation guidance is ISO/IEC 27002:2022 5.15.
What evidence supports 5.15?

Where this requirement comes from
This is our own statement of ISO 27001:2022 5.15, read from the copy we hold (licensed complete copy) and stated in our words, not the standard verbatim. The framework as we hold it.
Common gaps an assessor flags
- The access control policy exists but is not reflected in actual system configurations
- Default-allow rules persist in network or cloud environments
- Non-human entities such as service accounts are left outside the access rules
- Access rights are not aligned with classification, so sensitive data is broadly accessible
How it maps to SOC 2
- CC6.1 high An access control policy is the logical access architecture this criterion names.
- CC6.3 high The access control rule set defines role based access.
A link is a topical overlap with a confidence and a reason. It does not establish that meeting one requirement satisfies the other, and it is not certification.
