Name one method for ensuring the physical security of information assets in a DoD facility.

Access controls, such as badge systems or biometric scanners, are fundamental methods for ensuring the physical security of information assets in a DoD facility. These controls provide a mechanism to authenticate and verify the identity of individuals before granting them access to sensitive areas or information. By using badge systems, which often involve magnetic strips or RFID technology, facilities can manage entry points effectively, reducing the risk of unauthorized access.

Biometric scanners enhance security further by relying on unique physical characteristics, such as fingerprints or iris patterns, which are challenging to duplicate. This ensures that only authorized personnel can enter secure areas, minimizing the risk of data breaches and protecting essential information assets from threats.

The other options, while they might have security implications, do not provide the same level of assurance or effectiveness in protecting physical assets. Random security checks can help identify unauthorized individuals after they have breached a perimeter but do not prevent access in the first place. Limited visitor access with no tracking leaves room for potential risks as it does not monitor who is allowed in and out. Open access to all employees blatantly undermines security protocols, creating significant vulnerabilities in protecting valuable information.
