| Description | ||||
| Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. If OL 9 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. | ||||

Verify that OL 9 prevents the use of dictionary words for passwords with the following command:
$ grep dictcheck /etc/security/pwquality.conf /etc/pwquality.conf.d/*.conf
/etc/security/pwquality.conf:dictcheck=1
If "dictcheck" does not have a value other than "0", or is commented out, this is a finding.
