Commissioning proves a configuration at one point in time. Facility use, weather, wear, construction and staffing changes immediately begin to alter it. A lifecycle program should test whether each control still performs its assigned job and whether the layered system still supports response.
Maintenance is not limited to electronics. Walls, barriers, doors, glazing, foundations, hardware, utilities and operating procedures all need assigned ownership and evidence.
Maintain a security asset and requirement register
Record location, owner, performance objective, make or construction, approved configuration, inspection frequency, service history and related drawings. Include passive components such as wall systems, bollards and protected penetrations, not only powered devices.
Link each asset to the risk or requirement it supports. This prevents a camera or barrier from being removed as “unused” when its purpose is not obvious to maintenance personnel.
Inspect condition and function
Condition checks identify corrosion, impact damage, cracking, loose anchors, misalignment, blocked views and unauthorized modifications. Functional tests verify alarms, recording, communication, locks, releases, gates, backup power and monitoring.
Set frequency according to consequence, environment, manufacturer guidance, code and experience. High-use doors or exposed barriers may need more attention than protected passive assemblies.
Review people and procedures
Audit active credentials, keys, combinations, visitor records, contractor access and role assignments. Confirm that terminated or transferred users no longer retain access. Interview operators to identify nuisance alarms, workarounds and functions that appear correct in reports but fail in practice.
Exercise selected scenarios and record elapsed detection, assessment, notification and response times. Maintenance data should feed training and capital planning.
Track deficiencies to verified closure
| Field | Purpose |
|---|---|
| Deficiency | Clear condition, location and affected requirement. |
| Risk | Consequence and temporary exposure. |
| Compensation | Interim guard, route, barrier, monitoring or procedure. |
| Owner and date | Accountability and priority. |
| Closure evidence | Repair record, test, photograph and acceptance. |
Control configuration changes
Require review for new utilities, doors, furniture, parking, landscape, software, tenant layouts and operational changes that affect security. Update drawings and the asset register. After a significant change, repeat the relevant commissioning sequence rather than relying on visual inspection alone.
Frequently asked questions
How often should a physical security audit occur?
Use frequencies based on risk, regulation, environment and component use, with additional reviews after incidents, construction or operating changes.
What is the difference between maintenance and an audit?
Maintenance preserves or repairs components; an audit independently checks whether controls, evidence and procedures still meet the security requirement.
Should passive barriers be inspected?
Yes. Walls, bollards, foundations, glazing, anchors and penetrations can be damaged or altered even though they contain no powered equipment.
Need to frame a facility decision?
ISCoA helps owners organize physical security exposure, mitigation priorities and evidence requirements before product selection.
