Chapter 1 What’s New for FortiOS 5.2.1 : Security Profiles : Menu and Options Simplification : Application Control
  
Application Control
The following changes have been made to improve usability in the web-based manager:
A new category list has been made that appears on the sensor page, found by going to Security Profiles > Application Control. When you click on a category, a drop down menu appears, allowing the action for that category to be changed. You can also select to view all the application control signatures for that category.
Application signatures can be viewed by selecting View Application Signatures.
Application Overrides allow you to change the action taken for specific signatures/applications.
The application filter sorting criteria popularity, technology, and risk have been removed.
