The IDPS 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 IDPS validating user credentials must not be vulnerable to a replay attack possibly enabling an unauthorized user to gain access to any IDPS. A replay attack is a form of a network attack in which a valid session or series of IP packets is intercepted by a malicious user who at a later time transmits the packets to gain access to the target device.

Check Text ( C-42864r1_chk )
If authentication functionality is provided by the underlying platform's account management system or by a network authentication server rather than the IDPS application itself, this is not a finding. Verify the configuration for the management console and sensors requires access by a DoD approved replay-resistant authentication method, such as DoD PKI, SecureID, or DoD Alternate Token. If DoD PKI, SecureID, or DoD Alternate Token is not used for authentication, this is a finding.
