Replay-Resistant Authentication
03.05.04: Replay-Resistant Authentication

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


Not applicable - Not applicable
Planned - The implementation is planned
In progress - The implementation is currently in progress
Partially implemented - The control is partially implemented
Implemented - The control is fully implemented
Alternative implementation - There is an alternative implementation in place (e.g., shared responsibility or inherited implementation)
Description

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.
