ISC2 Certified in Cybersecurity (CC)Security OperationsEasy
A company is experiencing frequent unauthorized physical access attempts to its data center. The current security measures include card readers at the entrance and CCTV cameras. To enhance security and ensure only authorized personnel can enter, the security team decides to implement an additional layer of authentication that verifies a unique biological characteristic of the individual. Which physical security control is being implemented?
- AAccess control lists (ACLs)
- BBiometrics
- CSecurity guards
- DMantraps
Show answer & explanationAnswer & explanation
Correct answer: B. Biometrics
Biometrics utilize unique biological characteristics (like fingerprints or iris scans) for authentication, providing a strong additional layer of verification for physical access control.
Why the other options are wrong
- A. Access control lists (ACLs) are typically logical controls used in networks or operating systems, not physical access verification systems.
- C. Security guards are personnel, not a specific technological control that verifies unique biological characteristics.
- D. Mantraps are double-door systems that trap an individual between two doors, preventing piggybacking, but don't verify biological characteristics.
Biometric Authentication
A security process that relies on the unique biological characteristics of an individual to verify their identity.
- Uses unique biological traits (e.g., fingerprint, iris, face).
- Enhances physical and logical access control.
- Provides a strong form of authentication ('something you are').
