What must authorized personnel do before permitting another individual to enter a Sensitive Compartmented Information Facility (SCIF)?

Authorized personnel must confirm the individual's need-to-know and access before permitting entry into a Sensitive Compartmented Information Facility (SCIF) to ensure that only those who are both cleared and have a legitimate requirement for the information within that facility can access it. This process is crucial for maintaining the security and integrity of sensitive information, as SCIFs are designed to protect classified information from unauthorized disclosure.

The need-to-know principle is a fundamental aspect of information security within the DoD and other governmental operations. It dictates that individuals are only granted access to classified information when they require it for their official duties. By verifying need-to-know status alongside the individual's security clearance, authorized personnel protect sensitive information from potential leaks or misuse.

Other options, such as verifying an individual's last name or checking their email address, do not directly relate to the security protocols necessary for SCIF access. Ensuring that an individual has the correct badge might be a component of access control, but it does not address the essential aspect of need-to-know, which is critical when dealing with classified or sensitive information.
