Zorluk: OrtaPhysical Security Controls

An IT infrastructure team is designing physical security measures for a sensitive server room inside a corporate headquarters. The design must specifically prevent unauthorized individuals from tailgating authorized staff into the room and prevent electromagnetic signals from leaking outside the facility to mitigate physical signal eavesdropping. Which of the following physical security controls should be implemented to meet these requirements? (Select TWO.)

  2. Faraday cage enclosureCevap
  3. C
    Perimeter bollards
  4. D
    Kensington cable locks
  5. E
    Display privacy filters

Cevap

The correct physical security controls are an access control vestibule and a Faraday cage enclosure.
An access control vestibule features a dual-door interlocking mechanism that prevents more than one person from entering simultaneously, effectively stopping tailgating. A Faraday cage enclosure provides electromagnetic shielding to contain electronic emissions and block RF signals from being intercepted outside the facility.

Adım Adım Çözüm

1
Analyze the tailgating requirement
Tailgating occurs when an unauthorized person follows an authorized person through a secure doorway. An access control vestibule (mantrap) enforces interlocked entry, allowing only one person through at a time.
Single-person interlocked access controls directly eliminate piggybacking and tailgating threats.
2
Analyze the electromagnetic emissions leakage requirement
Faraday cages (or Faraday shielding) consist of conductive mesh or enclosures that shield equipment from emitting or receiving external radio frequency (RF) signals.
Shielding electromagnetic emissions prevents eavesdropping on wireless signals or unintentional RF radiation.
