In this course, you learn about QRadar network hierarchy fundamentals. IBM Security QRadar uses the network hierarchy objects and groups to organize network activity and monitor groups or services in your network.When you develop your network hierarchy, consider the most effective method for viewing network activity. The network hierarchy does not need to resemble the physical deployment of your network. QRadar supports any network hierarchy that can be defined by a range of IP addresses.
