What poses a physical security risk in an open office area?

Posting an access roster in public view poses a physical security risk in an open office area because it exposes sensitive information regarding who has authorized access to different areas of the facility. This information can be exploited by malicious individuals to gain unauthorized entry, create impersonation schemes, or launch targeted attacks.

Having a publicly visible access roster reduces the overall security posture, as it provides potential intruders with critical data that they can use to circumvent security measures. Maintaining the confidentiality of access lists is crucial to ensuring that only those with the proper authorization can enter restricted areas.

In comparison, using a Common Access Card (CAC) for facility access is a standard security practice that ensures only personnel with appropriate clearance can enter the premises, enhancing security rather than posing a risk. Similarly, challenging people without proper badges is a proactive security measure that helps maintain a safe environment by verifying the identity of individuals within the facility.
