The Arista Multilayer Switch must use FIPS-compliant mechanisms for authentication to a cryptographic module.

V-67197	AMLS-NM-200825	SV-81687r1_rule		Medium

Description

Unapproved mechanisms that are used for authentication to the cryptographic module are not verified and therefore cannot be relied upon to provide confidentiality or integrity, and DoD data may be compromised. Network devices utilizing encryption are 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.

Check Text ( C-67775r1_chk )
Review the device configuration via the “show running-config” command for the following statement: management ssh fips restrictions If this statement is not present, this is a finding.

Fix Text (F-73309r1_fix)

Enable FIPS restrictions via the following commands: Enable Configure Management ssh Fips restrictions Exit Additionally, the switch should be configured to use its Hardware Random Number Generator as a source of entropy for the SSH protocol. To enable this, configure: Enable Configure Management security Entropy source hardware Once this has been changed, regenerate the SSH RSA Keys with: Reset ssh hostkey rsa
