Information

AlmaLinux OS 9 must require the maximum number of repeating characters be limited to three when passwords are changed.

GROUP ID: V-269395
RULE ID: SV-269395r1050278

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 require the change of the number of repeating consecutive characters when passwords are changed by setting the "maxrepeat" option.

Add the following line to "/etc/security/pwquality.conf" (or modify the line to have the required value):

maxrepeat = 3
