Communication
The organization must decide what internal and external communication the ISMS needs, covering what is communicated, when, to whom, and how.
What the requirement asks
The organization must decide what internal and external communication the ISMS needs, covering what is communicated, when, to whom, and how.
What the guidance adds
Communication is expected to be planned: what, when, with whom and how. The guidance also asks who communicates, which matters when an incident message has to leave the organization. A communication plan that lists channels but no triggers is incomplete.
Status of the guidance. The guidance lens for 7.4 reads the draft, which is at stage 40.00 and is not published, against the published ISO/IEC 27001:2022 requirement above. It is our reading, not a quotation, and it is not a requirement.
What good looks like
Keep A communication plan or matrix stating topics, timing, audiences and channels for ISMS communication with the clause record, and give it an owner and a review date.
Evidence an assessor asks for
- Communication planningA communication plan or matrix stating topics, timing, audiences and channels for ISMS communication
- Communication planningRecords of communications carried out according to the plan
- Communication planningExternal communication arrangements, for example with customers, regulators and suppliers
- Communication planningEvidence the plan is reviewed
The question an assessor will ask
An assessor will ask for A communication plan or matrix stating topics, timing, audiences and channels for ISMS communication. The test for 7.4 is whether that record can be produced for a live sample, not whether the clause is described in a procedure.
Common gaps
- No communication plan exists, so communication is ad hoc
- External communication needs are not identified
- The plan is not followed in practice
- Responsibilities for communicating are not assigned
Before the next audit
Before the next audit, test this against one live record: no communication plan exists, so communication is ad hoc.
