Discussion

Inactive identifiers pose a risk to systems and applications because attackers may exploit an inactive identifier and potentially obtain undetected access to the system. Owners of inactive accounts will not notice if unauthorized access to their user account has been obtained. Operating systems must track periods of inactivity and disable application identifiers after 35 days of inactivity.

Check Content

Verify Nutanix OS is configured to disable user accounts after the password expires using the following command.

$ sudo grep -i inactive /etc/default/useradd
INACTIVE=0

If the "INACTIVE" value is set to "-1", a value greater than "35", or is commented out, this is a finding.
