Title

The operating system must use multifactor authentication for network access to privileged and non-privileged accounts. (Cat II impact)

Discussion

To assure accountability and prevent unauthenticated access, users must utilize multifactor authentication to prevent potential misuse and compromise of the system. Multifactor authentication requires using two or more factors to achieve authentication. Factors include: 1) something a user knows (e.g., password/PIN); 2) something a user has (e.g., cryptographic identification device, token); and 3) something a user is (e.g., biometric). Network access is defined as access to an information system by a user (or a process acting on behalf of a user) communicating through a network (e.g., local area network, wide area network, or the Internet). The DoD CAC with DoD-approved PKI is an example of multifactor authentication. Satisfies: SRG-OS-000105-GPOS-00052, SRG-OS-000106-GPOS-00053

Check Content

Verify the operating system uses multifactor authentication for network access to privileged and non-privileged accounts. If it does not, this is a finding. Ask the system administrator if multi-factor auth is used on the network.

Fix Text

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