Fix Recommendation

Configure the operating system to enforce password complexity by requiring that at least one special character be used by setting the "ocredit" option.

Log in to Nutanix CVM and run the following command.

$ ncli cluster edit-cvm-security-params enable-high-strength-password=true

Check Contents

Verify Nutanix AOS enforces password complexity by requiring that at least one special character be used.

Note: The value to require a number of special characters to be set is expressed as a negative number in "/etc/security/pwquality.conf".

Check the value for "ocredit" in "/etc/security/pwquality.conf" using the following command.

$ sudo grep ocredit /etc/security/pwquality.conf
ocredit=-1

If the value of "ocredit" is not set to a negative value, this is a finding.
