| 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. Password complexity is one factor of several that determines how long it takes to crack a password. The more complex a password, the greater the number of possible combinations that need to be tested before the password is compromised. |

| Check Text (C-75670r1091570_chk) |
| Verify that OL 9 requires the change of at least four character classes when passwords are changed. Verify the value of the "minclass" option in "/etc/security/pwquality.conf" with the following command: $ grep minclass /etc/security/pwquality.conf /etc/security/pwquality.conf.d/*.conf minclass = 4 If the value of "minclass" is set to less than "4", or is commented out, this is a finding. |
| Fix Text (F-75577r1091571_fix) |
| Configure OL 9 to require the change of at least four character classes when passwords are changed by setting the "minclass" option. Add the following line to "/etc/security/pwquality.conf" (or modify the line to have the required value): minclass = 4 |
