Zorluk: ZorPhysical Security Controls

A security technician is securing a dedicated equipment cabinet within a third-party colocation data center. The organization's security baseline requires preventing physical access to server hardware ports to block unauthorized hardware keyloggers, as well as containing electromagnetic emissions from critical cryptographic servers to prevent signal interception. Which combination of physical security controls directly addresses both of these specific requirements?

  1. Physical port blockers combined with a Faraday cage enclosureCevap
  2. B
    Perimeter anti-ram bollards combined with biometric door locks
  3. C
    Security guards combined with high-definition CCTV surveillance
  4. D
    Chassis intrusion switches combined with smart card door readers

Cevap

Physical port blockers combined with a Faraday cage enclosure
Physical port blockers physically lock unused USB, Ethernet, or serial ports to prevent unauthorized hardware keyloggers or rogue devices from being inserted. A Faraday cage enclosure provides electromagnetic shielding to prevent unwanted signal leakage and RF interception from sensitive computing equipment.

Adım Adım Çözüm

1
Analyze requirement 1: Prevent physical access to server hardware ports to stop unauthorized keyloggers or flash drives.
Identify physical port blockers (USB/RJ-45 locks) as the control designed to physically cap and disable open hardware ports.
Port blockers physically occupy ports and require a special key to remove, preventing unauthorized physical hardware attachments.
2
Analyze requirement 2: Prevent electromagnetic emissions and signal interception from sensitive server hardware.
Identify a Faraday cage (or RF shielding enclosure) as the control that absorbs or reflects electromagnetic radiation.
Faraday cages block radio frequency signals and electromagnetic emanations from leaving or entering an enclosure.
3
Synthesize the two required controls.
The correct combination is physical port blockers and a Faraday cage enclosure.
This pair directly mitigates both hardware port tampering and RF/electromagnetic leakage.
