Discussion

The use of longer passwords reduces the ability of attackers to successfully obtain valid passwords using guessing or exhaustive search techniques by increasing the password search space.

Check Content

Check the system password length setting. # grep PASSLENGTH /etc/default/passwd If PASSLENGTH is not set to 15 or more, this is a finding.

Fix Text

Edit /etc/default/passwd and set the PASSLENGTH variable to 15 or greater.
