Question

Difficulty: Very hardPhysical Security Controls

A datacenter administrator is designing physical security controls for a ground-floor server room located immediately adjacent to a public parking lot. Compliance regulations mandate that the facility implement measures to prevent physical perimeter breaches caused by vehicle impacts, while also preventing unauthorized interception of high-frequency electromagnetic RF emissions originating from wireless testing hardware inside the facility. Which TWO of the following physical security controls should the administrator implement to satisfy these requirements? (Select TWO.)

  1. Reinforced exterior steel bollards installed along the building perimeter lineAnswer
  2. A grounded Faraday cage enclosure integrated into the room's wall structureAnswer
  3. C
    An access control vestibule configured with anti-passback logic
  4. D
    Steel cable locks anchored directly to raised floor support beams
  5. E
    Polarized window privacy filters attached to exterior glass panes

Answer

The administrator should implement reinforced exterior steel bollards along the perimeter to mitigate vehicle impacts and integrate a grounded Faraday cage enclosure into the wall structure to prevent electromagnetic RF signal leakage.
Implementing steel bollards along the exterior perimeter line creates a physical barrier capable of stopping moving vehicles from breaching the building wall. Installing a grounded Faraday cage within the room envelope creates an electromagnetic shield that attenuates and blocks radio frequency (RF) signals, preventing eavesdropping on wireless hardware emissions.

Step-by-Step Solution

1
Identify the specific physical security threats defined in the scenario.
The scenario requires protection against two specific threat vectors: vehicular impact against ground-floor walls and electromagnetic RF signal interception.
Selecting appropriate physical security controls requires matching each control directly to the specific threat vector.
2
Evaluate physical barriers for kinetic impact defense.
Bollards are heavy vertical posts installed outside a facility designed specifically to stop vehicle ramming attacks.
Neither access control vestibules, cable locks, nor privacy screens offer structural kinetic protection against moving vehicles.
3
Evaluate signal containment controls for RF eavesdropping.
A Faraday cage utilizes grounded conductive enclosure materials to block electromagnetic emissions from escaping the server room.
Standard walls, privacy filters, and door access vestibules do not block or attenuate electromagnetic RF signal leakage.
