Information
The idle timeout period is the amount of time that an administrator will stay logged in to the GUI without any activity.
Rationale:
Best practice dictates settings admin idle timeout to prevent the risk of unauthorized access to the device by preventing someone from using a logged-in GUI on a PC that has been left unattended.
Impact:
This is to prevent someone from accessing the FortiGate if the management PC is left unattended.
Solution
To change the idle timeout in the GUI:
1) Login to FortiGate with Super Admin privileges
2) Go to 'System' > 'Settings'.
3) In the 'Administration Settings' section, set the 'Idle timeout' value to five minutes by typing 5.
4) Click Apply.
To change the idle timeout in the CLI:
config system global
set admintimeout 5
end
Default Value:
By default, it is set to five minutes.
