Description
The shorter the password, the lower the number of possible combinations that need to be tested before the password is compromised. Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Password length is one factor of several that helps to determine strength and how long it takes to crack a password. Use of more characters in a password helps to exponentially increase the time and/or resources required to compromise the password.

Check Text ( C-56522r824877_chk )
Verify TOSS enforces a minimum 15-character password length. The "minlen" option sets the minimum number of characters in a new password. Check for the value of the "minlen" option in "/etc/security/pwquality.conf" with the following command: $ sudo grep minlen /etc/security/pwquality.conf minlen = 15 If the command does not return a "minlen" value of 15 or greater, this is a finding.

Fix Text (F-56472r824878_fix)
Configure TOSS to enforce a minimum 15-character password length. Add the following line to "/etc/security/pwquality.conf" (or modify the line to have the required value): minlen = 15
