Abstract: A threat detection system for detecting malware can automatically decide, without manual expert-level interaction, the best set of features on which to train a classifier, which can result in the automatic creation of a signature-less malware detection engine. The system can use a combination of execution graphs, anomaly detection and automatic feature pruning. Execution graphs can provide a much richer structure of runtime execution behavior than conventional flat execution trace files, allowing the capture of interdependencies while preserving attribution (e.g., D happened because of A followed by B followed by C). Performing anomaly detection on this runtime execution behavior can provide higher order knowledge as to what behaviors are anomalous or not among the sample files. During training the system can automatically prune the features on which a classifier is trained based on this higher order knowledge without any manual intervention until a desired level of accuracy is achieved.

Abstract: 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.
