Fix Recommendation

Configure RHEL 10 to enforce a minimum 15-character password length.

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 to contain the "minlen" parameter:

minlen = 15

Check Contents

Verify RHEL 10 enforces a minimum 15-character password length with the following command:

$ sudo grep -s minlen /etc/security/pwquality.conf /etc/security/pwquality.conf.d/*.conf
/etc/security/pwquality.conf:minlen = 15

If the command does not return a "minlen" value of "15" or greater, does not return a line, or the line is commented out, this is a finding.
