CompTIA Security+ (SY0-501) — Question 322

An organization electronically processes sensitive data within a controlled facility. The Chief Information Security Officer (CISO) wants to limit emissions from emanating from the facility. Which of the following mitigates this risk?

Answer options

• A. Upgrading facility cabling to a higher standard of protected cabling to reduce the likelihood of emission spillage
• B. Hardening the facility through the use of secure cabinetry to block emissions
• C. Hardening the facility with a Faraday cage to contain emissions produced from data processing
• D. Employing security guards to ensure unauthorized personnel remain outside of the facility

Correct answer: C

Explanation

The correct answer is C because a Faraday cage effectively prevents electromagnetic emissions from escaping, thereby protecting sensitive data. While options A and B involve enhancing security, they do not specifically target emission containment. Option D focuses on physical security but does not address the emission risk directly.
