Vulnerability Discussion

To assure accountability, prevent unauthenticated access, and prevent misuse of the system, non-privileged users must utilize multifactor authentication for local access.

Multifactor authentication is defined as using two or more factors to achieve authentication.

Factors include:
1) Something you know (e.g., password/PIN);
2) Something you have (e.g., cryptographic identification device or token); and
3) Something you are (e.g., biometric).

A non-privileged account is defined as an operating system account with authorizations of a regular or non-privileged user.

Local access is defined as access to an organizational information system by a user (or process acting on behalf of a user) communicating through a direct connection without the use of a network.

The DoD CAC with DoD-approved PKI is an example of multifactor authentication.

Check

Verify the operating system uses multifactor authentication for local access to non-privileged accounts. If it does not, this is a finding.

Fix

Configure the operating system to use multifactor authentication for local access to non-privileged accounts.
