Which of the following should be considered to mitigate data theft when using CAT5 wiring?
The correct answer is D. EMI shielding. CAT5 (unshielded twisted pair) copper cabling emits electromagnetic signals as data travels through it. An attacker can use techniques like Van Eck phreaking or electromagnetic eavesdropping to capture those emissions from nearby without physically tapping the cable. EMI…

Explanation
CAT5 (unshielded twisted pair) copper cabling emits electromagnetic signals as data travels through it. An attacker can use techniques like Van Eck phreaking or electromagnetic eavesdropping to capture those emissions from nearby without physically tapping the cable. EMI (Electromagnetic Interference) shielding-using shielded twisted pair (STP) cable-wraps the conductors in a metallic foil or braid that contains the electromagnetic emissions, making interception much harder. CCTV provides physical surveillance but does not prevent signal interception. Environmental monitoring tracks conditions like temperature and humidity. Multimode fiber is a cable replacement, not a shielding solution for existing CAT5 wiring.
