Processor for processing events. Once the Event Processor receives an event, the
Category Router determines the appropriate Correlation Group to apply tests to
the event. Once complete, the event is passed through the Custom Rules Engine
to determine the custom rules that apply to the event. The event is then passed
through the Ariel database for storage and the Flow Context and Routing
components to determine if real-time flow analysis should be performed and if the
event should automatically generate a new offense or become part of an existing
offense. If this is the case, the event is sent to the Magistrate. If real-time flow
analysis is requested of the event, a request is sent to the Classification Engine to
determine routing.
