Description
Any password, no matter how complex, can eventually be cracked. Therefore, passwords need to be changed periodically. If the operating system does not limit the lifetime of passwords and force users to change their passwords, there is the risk that the operating system passwords could be compromised.

Confirm Nutanix AOS is configured to enforce a 60-day maximum password lifetime. $ sudo grep -i pass_max_days /etc/login.defs PASS_MAX_DAYS 60 If the "PASS_MAX_DAYS" parameter value is not "60" or less, or is commented out, this is a finding. $ sudo awk -F: '$5 > 60 {print $1 " " $5}' /etc/shadow If any results are returned that are not associated with a system account, this is a finding.
