A compound attack object combines multiple signatures and/or protocol anomalies into a single object. Traffic must match all of the combined signatures and/or protocol anomalies to match the compound attack object; you can specify the order in which signatures or anomalies must match. Use compound attack objects to refine your IDP policy rules, reduce false positives, and increase detection accuracy. A compound attack object enables you to be very specific about the events that need to occur before IDP identifies traffic as an attack. You can use And, Or, and Ordered and operations to define the relationship among different attack objects within a compound attack and the order in which events occur.
