Chapter 15 Unified Threat Management for FortiOS 5.0 : Intrusion protection : Enable IPS scanning : Creating an IPS sensor
  
Creating an IPS sensor
You need to create an IPS sensor and save it before configuring it with filters and entries.
To create a new IPS sensor
1. Go to Security Profiles > Intrusion Protection > IPS Sensors.
2. Select the Create New icon in the top of the Edit IPS Sensor window.
3. Enter the name of the new IPS sensor.
4. Optionally, you may also enter a comment. The comment will appear in the IPS sensor list and serves to remind you of the details of the sensor.
5. Select OK.
The IPS sensor is created and the sensor configuration window appears. A newly created sensor is empty and contains no filters or signatures. You need to add one or more filters or signatures before the sensor can take effect.
