Where should combinations to the entrance doors of various facilities be stored?

Storing combinations to the entrance doors of various facilities in a different accredited facility at the same or higher classification level is a security best practice. This approach ensures that sensitive information is kept secure and minimizes the risk of unauthorized access. By keeping the combinations in a separate, accredited facility, it helps to ensure that only personnel with the appropriate clearance can access this critical information, thereby enhancing security measures.

This method provides a level of separation that can protect against internal threats and unauthorized access, as only those with the necessary credentials would have access to the combination. Additionally, storing the combinations in a facility with the same or higher classification level aligns with protocols for safeguarding sensitive information, thus reducing vulnerabilities associated with centralized storage solutions.

Other options may not adequately safeguard this sensitive information. Storing combinations in the server room could increase risk if that room is accessed by unauthorized personnel. Keeping the information with the facility manager may not offer adequate protection if that individual has a high turnover rate or if their access protocols are not robust. Finally, having combinations in a shared drive can expose them to cyber threats and unauthorized access, making this option highly insecure. Overall, the selected option prioritizes secure handling and accessibility, essential for maintaining facility integrity.
