Modify administrator account Lockout Duration and Threshold values

Account lockout policies control how and when accounts are locked out of the FortiGate unit. These policies are described and implemented as follows:

Administrator account Lockout Duration

If someone violates the lockout controls by entering an incorrect user name and/or password, account lockout duration sets the length of time the account is locked. the lockout duration can be set to a specific length of time using a value between 1 and 4294967295 seconds. The default value is 60 seconds.

When it’s required use the CLI to modify the lockout duration as follow:

config system global

set admin-lockout-duration <integer>

end

Administrator account Lockout Threshold

The lockout threshold sets the number of invalid logon attempts that are allowed before an account is locked out. You may set a value that balances the need to prevent account cracking against the needs of an administrator who may have difficulty accessing their account.

Its normal for an administrator to sometimes take a few attempts to logon with the right password.

The lockout threshold can be set to any value from 1 to 10. The Default value is 3, which is normally a good setting. However, to improve security you could reduce it to 1 or 2 as long as administrators know to take extra care when entering their passwords.

Use the following CLI command to modify the lockout threshold:

config system global

set admin-lockout-threshold <integer>

end

 

Keep in mind that the higher the lockout value, the higher the risk that someone may be able to break into the FortiGate unit.
