Discussion

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 shorter the password, 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 Content

Verify the BIG-IP appliance is configured to use a properly configured authentication server that enforces a minimum 15-character password length. 

Navigate to the BIG-IP System manager >> System >> Users >> Authentication.

Verify "Authentication: User Directory" is configured for an approved remote authentication server that enforces a minimum of 15-character password length.

If the BIG-IP appliance is not configured to use a properly configured authentication server to enforce a minimum 15-character password length, this is a finding.
