Information Security Architecture - Review and Update, v1.0
Defines conformance and assessment criteria for verifying that an organization reviews and updates the information security architecture at an organization-defined frequency to reflect updates in the enterprise architecture.
If an assessment step references organization-defined elements (E.g. <organization-defined personnel or roles>, <organization-defined frequency>, etc.), corresponding citations/excerpts must be provided to confirm that the organization has established and documented these values and that they apply as referenced in the conformance criteria.
Similarly, if a "Selection" among multiple options (e.g. [Selection (one or more): as needed; ]) is specified, evidence must be provided to establish that the option(s) implemented by the organization have been defined and documented.
The assessment step shall not be marked as satisfied without this evidence.
