Decide what the ISMS needs communicated inside and outside the organization: the content, the timing, the audience, the person who speaks and the process used. Held link: the 27003 guidance on 5.2 has top management decide which outside parties receive the policy and keep confidential content out of an external version. Implementation points (general ISMS practice; the 27003 guidance text for 7.4 is not held): plan communications such as objectives to staff, requirements to suppliers, incidents to authorities and customers, and performance to top management, and authorise who may speak externally.
This control maps to 7 controls across 5 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 7 it maps to, and the evidence behind each claim, over MCP and REST.
