Information

AlmaLinux OS 9 must enforce password complexity by requiring that at least one numeric character be used.

GROUP ID: V-269393
RULE ID: SV-269393r1050276

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.

Solution

Configure AlmaLinux OS 9 to enforce password complexity by requiring at least one numeric character be used by setting the "dcredit" option.

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:

dcredit = -1

Remove any configurations that conflict with the above value.
