Title
The operating system must enforce a minimum 15-character password length. (Cat II impact)
Discussion
The minimum password length must be set to 15 characters. 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. The use of more characters in a password helps to exponentially increase the time and/or resources required to compromise the password.
Check Content
To check the currently applied policies for password and accounts, use the following command: sudo system_profiler SPConfigurationProfileDataType | grep minLength The parameter minLength should be '15'. If it is less than '15', this is a finding.
Fix Text
This setting is enforced using the "Passcode Policy" configuration profile. NOTE: Updates to password restrictions must be thoroughly evaluated in a test environment. Mistakes in configuration may block password change and local user creation operations, as well as, lock out all local users, including administrators.
