Annex A 7.1
Physical security perimeters
Perimeters are defined and used to protect areas containing information and other associated assets.
What an assessor looks for
Show where the perimeters are and what each protects. Assessors typically walk them, so documentation and the building need to agree.
Where it usually fails
The documented perimeter no longer matches the premises after an office move or reconfiguration.
