| 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. |

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. |
