Abstract: An intrusion detection and analysis system and method are disclosed. The system includes a data monitoring device comprising a capture engine operable to capture data passing through the network and configured to monitor network traffic, decode protocols, and analyze received data. The system further includes an intrusion detection device comprising a detection engine operable to perform intrusion detection on data provided by the data monitoring device. Application program interfaces are provided and configured to allow the intrusion detection device access to applications of the data monitoring device to perform intrusion detection. The system also includes memory for storing reference network information used by the intrusion detection device to determine if an intrusion has occurred.

Abstract: A system, method and computer program product are provided for filtering communications over a network. Initially, a user is allowed to select from a plurality of network communication protocol layers associated with communications over a network. This may be accomplished in any manner such as allowing the user to select from the layers themselves, various faults that are inherent to certain layers, etc. An adaptive filter is then generated which is capable of collecting communications only involving the selected network communication protocol layers based on the user selection. Such adaptive filter is then used to collect the communications involving the selected network communication protocol layers. Further, an analysis process is executed for analyzing information at the selected network communication protocol layers of the collected communications for the detection of faults therein.
