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