FGFW-ND-000220 - The FortiGate device must enforce a minimum 15-character password length.

Information

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.

Log in to the FortiGate GUI with Super-Admin privilege.

1. Click System.
2. Click Settings.
3. Navigate to Password Policy.
4. On the Password scope option, click Admin.
