Nutanix OS must require users to reauthenticate for privilege escalation.

Description
Without reauthentication, users may access resources or perform tasks for which they do not have authorization. When operating systems provide the capability to escalate a functional capability, it is critical that the user reauthenticate.

Who does this work

7 NICE work roles and 5 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-279598r1192561_chk)

For AHV, this requirement is Not Applicable. Confirm Nutanix OS is configured as shown for reauthentication in the sudoers file: $ grep -i nopasswd /etc/sudoers /etc/sudoers.d/* If any occurrences of "NOPASSWD" are returned from the command and have not been documented with the information system security officer (ISSO) as an organizationally defined administrative group using multifactor authentication (MFA), this is a finding.

Fix Text (F-84056r1192560_fix)

Remove occurrences of "NOPASSWD". 1. For AOS, use the following command. salt-call state.sls security/CVM/manualCVM 2. For Prism Central, use the following command. salt-call state.sls security/PCVM/manualPCVM 3. For Files, use the following command. salt-call state.sls security/AFS/manualAFS 4. The AHV hypervisor does not support local interactive user accounts. AHV has been designed and configured to run essentially headless. The only accounts allowed on AHV are the preconfigured system accounts.
