Fix Recommendation

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

Add the following line to "/etc/security/pwquality.conf conf" (or modify the line to have the required value):

minclass = 4

Check Contents

The "minclass" option sets the minimum number of required classes of characters for the new password (digits, uppercase, lower-case, others).

Check for the value of the "minclass" option in "/etc/security/pwquality.conf" with the following command:

# grep minclass /etc/security/pwquality.conf
minclass = 4

If the value of "minclass" is set to less than "4", this is a finding.
