Abstract
Techniques for responding to intrusions on a packet switched network include receiving user data at a subscriber-aware gateway server between a network access server and a content server. The user data includes subscriber identifier data that indicates a unique identifier for a particular user, network address data that indicates a network address for a host used by the particular user, NAS data that indicates an identifier for the network access server, flow list data that indicates one or more open data packet flows, and suspicious activity data. The suspicious activity data indicates a value for a property of the open data packet flows that indicates suspicious activity. It is determined whether an intrusion condition is satisfied based on the suspicious activity data. If the intrusion condition is satisfied, then the gateway responds based at least in part on user data other than the network address data.
