| 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 the password, the greater the number of possible combinations that need to be tested before the password is compromised.

| ℹ️ Check |
|---|
| Verify that RHEL 9 enforces password complexity rules for the root account. Check if root user is required to use complex passwords with the following command: $ grep enforce_for_root /etc/security/pwquality.conf /etc/security/pwquality.conf.d/*.conf /etc/security/pwquality.conf:enforce_for_root If "enforce_for_root" is commented or missing, this is a finding. |
| ✔️ Fix |
|---|
| Configure RHEL 9 to enforce password complexity on the root account. Add or update the following line in the "/etc/security/pwquality.conf" file or a configuration file in the "/etc/security/pwquality.conf.d/" directory to contain the "enforce_for_root" parameter: enforce_for_root |
