CompTIA Server+ (SK0-005)Security and Disaster RecoveryHard
A company is planning a new data center and needs to implement robust physical security measures. Which of the following would provide the strongest deterrent against unauthorized physical access to the server racks, beyond standard locked doors?
- ASecurity guards patrolling the facility 24/7.
- BIP-based surveillance cameras monitoring all aisles.
- CBiometric access controls at the data center entrance.
- DIndividual rack-level locking mechanisms with audit trails.
Show answer & explanationAnswer & explanation
Correct answer: D. Individual rack-level locking mechanisms with audit trails.
While all options enhance security, individual rack-level locking mechanisms directly prevent unauthorized access to the servers themselves, even if an intruder gains entry to the data center floor. Combined with audit trails, this offers precise control and accountability at the most granular level.
Why the other options are wrong
- A. Security guards provide a human deterrent and response, but their effectiveness can vary, and they cannot be everywhere at once to prevent rack-level tampering.
- B. Surveillance cameras detect and record, acting as a deterrent and forensic tool, but do not physically prevent access.
- C. Biometric controls secure entry to the facility but not necessarily access to individual racks once inside.
Rack-Level Physical Security
Physical security measures applied directly to server racks, such as locking mechanisms, to prevent unauthorized access to individual servers and equipment.
- Provides granular control over server access.
- Adds a layer of security even if data center perimeter is breached.
- Often includes audit trails for accountability.
Memory trick: Layers of security: Perimeter, Building, Room, Rack.
