Zorluk: OrtaPhysical Security Controls

A network technician is configuring networking equipment inside an intermediate distribution frame (IDF) room shared with third-party facility contractors. Although the room itself requires keycard access, several unassigned Ethernet switch ports on the rack remain exposed, creating a risk of unauthorized physical connection to the internal network. Which of the following physical security controls should the technician implement to directly prevent unauthorized network cable insertions into these exposed ports?

  1. Physical port locksCevap
  2. B
    Cable locks
  3. C
    Privacy filters
  4. D
    Faraday enclosures

Cevap

Physical port locks are the correct choice because they physically block unused RJ-45 switch ports from unauthorized network connections.
Physical port locks (such as RJ-45 port blockers) fit directly into open networking ports and require a specific key to remove. This prevents unauthorized users from physically connecting rogue devices or network cables into the switch.

Adım Adım Çözüm

1
Analyze the physical security vulnerability described in the scenario.
Unused Ethernet switch ports in a shared room are physically accessible and vulnerable to unauthorized device connections.
Identify the precise physical threat vector (unauthorized wired connection to network switch interfaces).
2
Evaluate the controls against the requirement to secure individual interface ports.
Physical port locks prevent network cables or hardware dongles from being inserted into RJ-45 or USB interfaces without a specialized removal key.
Port locks provide granular interface-level protection when general room access cannot completely eliminate unauthorized personnel presence.
