A system and method for analyzing events from devices relating to network security, includes a device interface(s), for receiving events from devices. One or more processors, responsive to the event received pursuant to the device interfaces, evaluate the event in accordance with rules, wherein the rules define, inter alia, an operation the system is to take to evaluate the event and an action to be taken under specified conditions. Also, the processor can determine, responsive to the received event, whether the event is of interest, and if not, discarding the event. The processor can provide a correlation corresponding to the at least one event, for the rules.
