Details

Check Text (C-230377r1017188_chk)

Verify RHEL 8 prevents the use of dictionary words for passwords. Determine if the field "dictcheck" is set with the following command: $ sudo grep -r dictcheck /etc/security/pwquality.conf* /etc/security/pwquality.conf:dictcheck=1 If the "dictcheck" parameter is not set to "1", or is commented out, this is a finding. If conflicting results are returned, this is a finding.

Fix Text (F-33021r858788_fix)

Configure RHEL 8 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 Remove any configurations that conflict with the above value.
