Verify TOSS prevents the use of dictionary words for passwords. Determine if the field "dictcheck" is set in the "/etc/security/pwquality.conf" or "/etc/security/pwquality.conf.d/*.conf" files with the following command: $ sudo grep -r dictcheck /etc/security/pwquality.conf /etc/security/pwquality.conf.d /etc/security/pwquality.conf:dictcheck=1 If the "dictcheck" parameter is not set to "1", or is commented out, this is a finding.

Fix Text (F-56499r824959_fix)
Configure TOSS to prevent the use of dictionary words for passwords. Add or update the following line in the "/etc/security/pwquality.conf" file or a configuration file in the /etc/pwquality.conf.d/ directory to contain the "dictcheck" parameter: dictcheck=1
