I have using FortiOS 5.4.13, and I am suffering by application control.
I tried to created new application sensor using below instruction.
But there is no "create new" icon in the title bar.
Is that any solution?
If you click the menu item "Application Control", usually the first AC profile opens in the right pane (e.g. "default").
There is a dropdown list field in the top right corner where you can select other profiles to edit.
Right beside the dropdown there is a cross icon. Click on that to create a new profile.
I found the solution finally,
Prior to the "Create New" icon appeared, I have to enable the "Multiple Security Profile" in order to make the icon showed.
