Chapter 15 Unified Threat Management for FortiOS 5.0 : Data leak prevention : Creating a DLP sensor
  
Creating a DLP sensor
DLP sensors are collections of filters. You must also specify an action for the filter when you create it in a sensor. Once a DLP sensor is configured, you can select it a security policy profile. Any traffic handled by the security policy will be examined according to the DLP sensor configuration.
To create a DLP sensor
1. Go to Security Profiles > Data Leak Prevention > Sensor.
2. Select the Create New icon on the Edit DLP Sensor window title bar.
3. In the Name field, enter the name of the new DLP sensor.
4. Optionally, you may also enter a comment. The comment appears in the DLP sensor list and can remind you of the details of the sensor.
5. Select OK.
The DLP sensor is created and the sensor configuration window appears.
6. Select OK.
A newly created sensor is empty, containing no filters. Without filters, the DLP sensor will do nothing.
