Answer :
Final answer:
The access control system for unattended SCIF entry must use an access card and personal identification number (PIN) for authentication.
Explanation:
An access control system is a security measure used to regulate and monitor access to a secure area, such as a SCIF (Sensitive Compartmented Information Facility). In the case of unattended SCIF entry, where there is no human presence to verify access, a combination of two factors is typically used: an access card and a personal identification number (PIN).
The access card is a physical card that contains encoded information, such as a magnetic strip or RFID chip, which is used to identify the individual. It is issued to authorized personnel and serves as their credential for accessing the SCIF. The access card is unique to each individual and cannot be easily duplicated or forged.
The personal identification number (PIN) is a unique numeric code that the individual must enter to authenticate their identity. It acts as a second factor of authentication, in addition to the access card. The PIN is typically entered using a keypad or touchscreen interface. It is important to keep the PIN confidential and not share it with others.
By requiring both the access card and the PIN, the access control system ensures a higher level of security and prevents unauthorized access to the SCIF. This two-factor authentication process adds an extra layer of protection, as it requires something the individual possesses (the access card) and something they know (the PIN).
