For accounts using password authentication, the Cisco ISE must implement replay-resistant authentication mechanisms for network access to privileged accounts.
An XCCDF Rule
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. 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.

A Manual Procedure
Enable FIPS Mode in Cisco ISE to ensure FIPS 140-2/3 algorithms are used in all security functions requiring cryptographic functions.
1. Choose Administration >> System >> Settings >> FIPS Mode.
2. Choose the "Enabled" option from the FIPS Mode drop-down list.
3. Click "Save" and restart the node.
NOTE: Configuring FIPS mode is the required DoD configuration. However, this requirement can be lowered to a CAT 3 if the alternative manual configuration is used to configure individual protocols.
