Network Zones by Peer Group
The Network Zones by Peer Group model determines if a user's network zone is significantly different from that user's defined group.
Enable the Network Zones by Peer Group to determine if a user's network zone
is significantly different from the user's defined group. If the user's network zone is deemed
suspicious, a Sense Event is generated to increase the user's risk score. Users are grouped and
analyzed based on the Group by field.
Important: You must have a
minimum of two defined groups that each contains 5 or more users. If you change the group selection,
a new model needs to be constructed. A significant amount of time and computer resources are
required to complete the model creation. It is not recommended to change this value
frequently.
