periodic reviewEvidence produced at each review
- Evidence the perimeter is physically sound, covering walls, doors, windows, roof and floor voids · Physical access / facilities
- Records of inspection or testing of perimeter integrity · Physical access / facilities
- Evidence covering shared and multi tenant buildings, including the boundary between the organisation and other occupants · Physical access / facilities
governing documentDocuments that govern the control
- Definition of the security perimeters, with site plans or drawings showing the boundary of each area holding information and associated assets · Policy repository / GRC workspace
- The basis for each perimeter, tied to the classification and criticality of what it protects · Policy repository / GRC workspace
First move
This control is evidenced by people and documents, not systems. Put the document under version control with an owner and review date, and log each review as a record with reviewer and date. Do not try to automate it.
Common gaps auditors find
- Perimeter defined at the building line only, with no internal perimeter around the areas that actually hold sensitive assets
- Fire escapes, service risers, delivery bays and false ceilings bypassing the documented perimeter
- Shared building risks unassessed, so a neighbouring tenant's space adjoins a secure area
- Perimeter documented at design and never re inspected as the building was altered
