What type of identifier could be a risk if mishandled?

The Common Access Card (CAC) is a key identifier for individuals within the US Navy and other Department of Defense agencies. It serves multiple purposes, including identification, authentication, and access to secure facilities and systems. If mishandled, a CAC can pose significant security risks.

For instance, if someone gains unauthorized access to a CAC, they could impersonate the cardholder, gaining access to sensitive information or restricted areas. The CAC contains a wealth of personal and professional information that could lead to identity theft or breaches of confidential data. Each user’s credentials tied to their CAC are crucial for maintaining the integrity of military operations and communications.

While other identifiers also present risks, such as Social Security Numbers, phone numbers, and credit card numbers, the CAC's role as a physical access and authentication tool makes its mishandling particularly impactful in a military context. It is therefore vital to manage CACs with a high level of security and responsibility to mitigate potential risks associated with their misuse.
