03.05.04 Replay-Resistant Authentication

Statement

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

Guidance

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.

Assessment objective

replay-resistant authentication mechanisms for access to privileged accounts are implemented.

Assessment objective

replay-resistant authentication mechanisms for access to non-privileged accounts are implemented.

Assessment method

• identification and authentication policy and procedures system design documentation system audit records system configuration settings list of privileged system accounts system security plan other relevant documents or records

Assessment method

• personnel with system operations responsibilities personnel with account management responsibilities personnel with information security responsibilities system developers system administrators

Assessment method

• mechanisms for supporting or implementing identification and authentication capabilities mechanisms for supporting or implementing replay-resistance
