Domain segmentation
Segmenting your network into different domains
helps to ensure that relevant information is available only to those
users that need it.
You can create security profiles to limit the information that is available to a group of users within that domain. Security profiles provide authorized users access to only the information that is required to complete their daily tasks. You modify only the security profile of the affected users, and not each user individually.
You can also use domains to manage overlapping IP address ranges. This method is helpful when you are using a shared IBM® QRadar® infrastructure to collect data from multiple networks. By creating domains that represent a particular address space on the network, multiple devices that are in separate domains can have the same IP address and still be treated as separate devices.
