Title

The container platform must implement replay-resistant authentication mechanisms for network access to non-privileged accounts. (Cat II impact)

Discussion

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. A non-privileged account is any operating system account with authorizations of a non-privileged user. 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.

Check Content

Review the container platform configuration to determine if the container platform is configured to provide replay-resistant authentication mechanisms for network access to non-privileged accounts. If the container platform is not configured to provide replay-resistant authentication mechanisms for network access to non-privileged accounts, this is a finding.

Fix Text

Configure the container platform to provide replay-resistant authentication mechanisms for network access to non-privileged accounts.
