Certified Information Systems Security Professional (CISSP) — Question 417

The existence of physical barriers, card and personal identification number (PIN) access systems, cameras, alarms, and security guards BEST describes this security approach?

Answer options

• A. Access control
• B. Security information and event management (SIEM)
• C. Defense-in-depth
• D. Security perimeter

Correct answer: C

Explanation

The correct answer is C, as defense-in-depth refers to a layered security strategy that employs multiple security measures to protect assets. While access control (A) and security perimeter (D) are components of this strategy, they do not encompass the comprehensive approach indicated by the presence of various security measures. Security information and event management (SIEM) (B) focuses on monitoring and analyzing security events rather than physical security measures.
