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 of several factors 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. |

The "maxrepeat" option sets the maximum number of allowed same consecutive characters in a new password. Check for the value of the "maxrepeat" option in "/etc/security/pwquality.conf" with the following command: # grep maxrepeat /etc/security/pwquality.conf maxrepeat = 3 If the value of "maxrepeat" is set to more than "3", this is a finding. |

Configure the operating system 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 conf" (or modify the line to have the required value): maxrepeat = 3 |
