Identification and Authentication (IA)

Employ replay-resistant authentication mechanisms for network access to privileged and non-privileged accounts.

Level N/A

Authentication processes resist replay attacks if it is impractical to successfully authenticate by recording or replaying previous authentication messages. Replay-resistant techniques include protocols that use nonces or challenges such as time synchronous or challenge-response one-time authenticators. [SP 800-63-3] provides guidance on digital identities.
