Leadership has formally approved and sponsored the security programme
Sekit's Security charter is part of A.5.1's topic-specific policy layer: it is a management-signed statement naming an accountable owner and granting that person a mandate to act.
The security charter names the accountable owner and grants that person a management mandate, supporting A.5.2's requirement to document who holds overall responsibility for the security programme.
This policy control establishes the signed charter naming an accountable security owner with a mandate to act, the foundation A.5.4's management enforcement depends on.
