Fix Recommendation

Configure OL 8 to require the change of at least four character classes when passwords are changed by setting the "minclass" option.

Add or update the following line in the "/etc/security/pwquality.conf" file or a configuration file in the "/etc/security/pwquality.conf.d/" directory:

minclass = 4

Remove any configurations that conflict with the above value.

Check Contents

Verify the value of the "minclass" option in "/etc/security/pwquality.conf" or "/etc/security/pwquality.conf.d/*.conf" files with the following command:

$ sudo grep -r minclass /etc/security/pwquality.conf*

/etc/security/pwquality.conf:minclass = 4

If the value of "minclass" is set to less than "4" or is commented out, this is a finding.
If conflicting results are returned, this is a finding.
