User passwords must be at least 15 characters in length.

Password complexity, or strength, is a measure of the effectiveness of a password in resisting 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. The shorter the password is, the lower the number of possible combinations that need to be tested before the password is compromised.

Use of more characters in a password helps to exponentially increase the time and/or resources required to compromise the password.

Check the system password length setting.

# grep ^PASSLENGTH /etc/default/passwd

If PASSLENGTH is not set to 15 or more, this is a finding.

The root role is required.

# pfedit /etc/default/passwd 

Locate the line containing:

PASSLENGTH

Change the line to read:

PASSLENGTH=15
