A remote, unmanned compressor station in a gas pipeline has no on-site staff. Which combination of measures best maintains physical security and detects intrusion at the site?
- A.Relying solely on a posted warning sign at the gate
- B.Perimeter fencing, locked enclosures, intrusion alarms, and remote video with tamper detection
- C.Scheduling a quarterly visit by a maintenance contractor
- D.Disabling all network connectivity to the station
Why B is correct
Unmanned sites require layered physical controls because no one is present to respond, so fencing, locked cabinets, intrusion and tamper sensors, and remotely monitored cameras provide both deterrence and timely detection. Infrequent visits or signage alone leave long windows for undetected tampering.
