Video: Example of DLP using a File Filter configuration.
Before your FortiGate unit can filter files by pattern or type, you must create a file filter list. The action triggered by the contents of a file filter list will be decided in the sensor so it is important to make sure that when you are building a list that you intend for the same action to be applied to all of the entries in the same list.
To create a file filter list
1. Go to Security Profiles > Data Leak Prevention > File Filter.
2. Select Create New.
3. Enter a Name for the new file filter list.
4. Select OK.
The new list is created and the edit file filter list window appears. The new list is empty. You need to populate it with one or more file patterns or file types.
