Protection of Critical Infrastructure
What this domain tests
This domain tests how a private guard applies protection to Nigeria's critical national assets and infrastructure (CNII): power, oil and gas, water, telecoms, transport, health, financial and government facilities. The exam looks for risk-based thinking, layered security and correct reporting, not heroic confrontation.
Core rules and concepts
- Critical infrastructure is a system or asset whose loss would seriously harm national security, the economy, or public safety. Protection aims to deter, detect, delay, respond and recover.
- Risk is assessed as threat × vulnerability × consequence. A site plan should identify assets, access points, blind spots, key persons and dependencies such as power or communications.
- Use layers: perimeter fencing, lighting and clear zones; gate control with ID checks, vehicle screening and visitor logs; internal zoning, escorts and CCTV; monitored alarms; trained patrols and response liaison.
- Guards observe, record and report. They do not repair equipment, investigate beyond training, or confront armed intruders. Control rooms and SCADA cabinets need restricted access and anomaly reporting.
- Coordinate with facility management, NSCDC, police and emergency services; share information and test alarms and drills.
Worked example
A pipeline pumping station has an unlit rear fence and one gate. Threat: tampering. Vulnerability: easy approach and no detection. Consequence: fire, injury, supply disruption. Controls: clear vegetation, repair lighting, add CCTV and alarm, enforce one controlled gate, log vehicles, run two-person patrols and test alarms. Reasoning: these measures lower vulnerability and shorten detection-to-response time; guards report tampering rather than attempt repairs.
Traps that cost marks
Treating critical infrastructure as only oil pipelines; ignoring cyber and insider threats; believing CCTV prevents intrusion rather than detects it; escalating without reporting; and leaving no written record.
