RHEL-08-020300 - RHEL 8 must prevent the use of dictionary words for passwords.

Information

If RHEL 8 allows the user to select passwords based on dictionary words, this increases the chances of password compromise by increasing the opportunity for successful guesses, and brute-force attacks.

Solution

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.
