Annex A 5.29
Information security during disruption
Security is maintained at an appropriate level during disruption, rather than suspended to restore service.
What an assessor looks for
Show that continuity plans preserve controls, including any temporary access granted during recovery and how it is revoked afterwards.
Where it usually fails
Recovery procedures grant broad emergency access with no mechanism to remove it once normal service resumes.
