The UEM server must implement replay-resistant authentication mechanisms for network access to non-privileged accounts.

Description
A replay attack may enable an unauthorized user to gain access to the application. Authentication sessions between the authenticator and the application validating the user credentials must not be vulnerable to a replay attack. An authentication process resists replay attacks if it is impractical to achieve a successful authentication by recording and replaying a previous authentication message. A non-privileged account is any operating system account with authorizations of a non-privileged user. Techniques used to address this include protocols using nonces (e.g., numbers generated for a specific one-time use) or challenges (e.g., TLS, WS_Security). Additional techniques include time-synchronous or challenge-response one-time authenticators. Satisfies: FIA Reference:PP-MDM-414003

Check Text ( C-37549r614102_chk )
Requirement is Not Applicable when UEM server is configured to use DoD Central Directory Service for administrator account authentication. Verify the UEM server implements replay-resistant authentication mechanisms for network access to non-privileged accounts. If the UEM server does not implement replay-resistant authentication mechanisms for network access to non-privileged accounts, this is a finding.
