WTM must enable FIPS mode so only FIPS 140-3-approved algorithms for authentication to a cryptographic module are selectable for use.

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.

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.

1. Log in to the SSH CLI. 2. Enter "configure terminal". 3. Enter "crypto tls cipher ECDHE-ECDSA-CHACHA20-POLY1305 dis". 4. Enter "crypto tls cipher TLS_CHACHA20_POLY1305_SHA256 dis". 5. Enter "crypto tls cipher ECDHE-RSA-CHACHA20-POLY1305 dis". 6. Enter "crypto ssh kex curve25519-sha256 dis". 7. Enter "crypto fips-mode enabled". 8. Enter "Commit" and accept the warnings. 9. Press "Enter" to reboot.
