YouTube - NIST 800-171 Control 3.5.4 Employ replay-resistant authentication mechanisms for network access
In this edition of the On Call Compliance Solutions Compliance Tip of the Week, we focus on how 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. Let’s talk about NIST 800-171 Control 3.5.4 Employ replay-resistant authentication mechanisms for network access to privileged and nonprivileged accounts.
