The network device must use organizationally defined replay-resistant authentication mechanisms for network access to privileged accounts.

Description
All authentication credentials must be maintained on an authentication server. Messages between the authenticator and the network device validating user credentials must not be vulnerable to a replay attack possibly enabling an unauthorized user to gain access to any network device. A replay attack is a network attack in which a valid session or series of IP packets is intercepted by a malicious user who later transmits the packets to gain access to the target device.

Check Text ( C-SRG-NET-000146-NDM-000106_chk )
If authentication functionality is provided by the underlying platform's account management system or by a network authentication server rather than the network device application itself, this is not a finding. Verify the configuration for the network device requires access by a DoD-approved replay-resistant authentication method, such as DoD PKI or DoD Alternate Token. If DoD PKI or DoD Alternate Token is not used for authentication, this is a finding.
