Nutanix AOS pam_unix.so module must be configured in the password-auth file to use a FIPS 140-2 approved cryptographic hashing algorithm for system authentication.
An XCCDF Rule
Description
<VulnDiscussion>Unapproved mechanisms 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. Operating systems 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. This allows for Security Levels 1, 2, 3, or 4 for use on a general purpose computing system.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Remediation - Manual Procedure
Configure the pam.d modules to comply with FIPS 140-2:
1. Enable high-strength passwords:
$ ncli cluster edit-cvm-security-params enable-high-strength-password=true
2. After enabling the high-strength passwords, the system will process the salt stack to enable the DoD versions of the pam.d files. Recheck the Check Text for compliance.
