For access to SCIFs during business hours, cipher locks may be used for high security areas.

• A. True
• B. False
• C. Only for low-security areas
• D. Not permitted at all

Answer: (A)

Cipher locks are an appropriate entry control for SCIFs during business hours because they provide electronic authentication and an audit trail of who enters the high-security area. They allow authorized personnel to gain timely access without handing out physical keys, while keeping a record of entries for accountability. While SCIF access may still involve additional safeguards like dual-control when required by policy, the use of cipher locks themselves supports secure, controlled access in daytime operations. So the statement is true. The other options aren’t correct because cipher locks are not restricted to low-security areas, nor are they universally forbidden for SCIF access.
