Discussion

Unapproved mechanisms that are used for authentication to the cryptographic module are not validated and therefore cannot be relied upon to provide confidentiality or integrity, and DOD data may be compromised. Sentry utilizing encryption is required to use FIPS-compliant mechanisms for authenticating to cryptographic modules. FIPS 140-2 is the current standard for validating that mechanisms used to access cryptographic modules utilize authentication that meets DOD requirements. However, authentication algorithms must configure security processes to use only FIPS-approved and NIST-recommended authentication algorithms.

Verify the Sentry uses encryption services that implement NIST FIPS-validated cryptography to protect the confidentiality of remote access sessions. 

On the Sentry CLI console, do the following:
1. SSH to Sentry Server from any SSH client.
2. Enter the administrator credentials set at Sentry installation.
3. Enter "enable".
4. When prompted, enter the "enable secret" set at Sentry installation.
5. Enter "show FIPS".
6. Verify "FIPS 140 mode is enabled" is displayed.

If the Sentry Server does not report that FIPS mode is "enabled", this is a finding.
