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 DoW data may be compromised. Network devices utilizing encryption are required to use FIPS-compliant mechanisms for authenticating to cryptographic modules. FIPS 140-3 is the current standard for validating that mechanisms used to access cryptographic modules utilize authentication that meets DoW requirements. However, authentication algorithms must configure security processes to use only FIPS-approved and NIST-recommended authentication algorithms. Satisfies: SRG-APP-000179-NDM-000265, SRG-APP-000411-NDM-000330, SRG-APP-000224-NDM-000270, SRG-APP-000172-NDM-000259, SRG-APP-000142-NDM-000245, SRG-APP-000412-NDM-000331

Check Content

1. Log in to the SSH CLI.
2. Enter "show crypto fips-mode-status".

If "show crypto fips-mode-status" is not set to "true", this is a finding.
