Learn about IDS signatures

Network traffic is the machine-to-machine activity to and from your environment, and it is monitored by the Network IDS appliance. Network activity, unlike activity logs, is governed by internet standards, including TCP/IP, HTTP, HTTPS, DNS, and many others. Therefore, suspicious activity can be identified by looking for patterns in the traffic, commonly known as "signature" network patterns. IDS signatures recognize a specific type of activity to generate events. Analytics can evaluate these events to generate incidents and observations.

To learn how to install and configure a physical Network IDS, see Install and Configure the Physical Appliance.

To learn how to install and configure a virtual Network IDS, see Install and Configure the Virtual Appliances.
