| Description | ||||
| Using 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 a password, the greater the number of possible combinations that must be tested before the password is compromised. | ||||

Check Text (C-282453r1200339_chk)
Verify the value of the "maxrepeat" option in "/etc/security/pwquality.conf" using the following command:
$ grep maxrepeat /etc/security/pwquality.conf
maxrepeat = 3
If the value of "maxrepeat" is set to more than "3", or is commented out, this is a finding.
Fix Text (F-86919r1200338_fix)
Configure TOSS 5 to require changing 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
