摘要： Disclosed herein is an anomaly detection method for link-state routing protocols, a link-state routing protocol providing for link-state update (LSU) messages to be exchanged between nodes in a packet-based network, wherein each link-state update message includes link-state advertisement (LSA) message(s) each having a respective header. The method comprises monitoring the link-state advertisement messages exchanged in the network, extracting and forming respective feature vectors with the values in the fields of the headers of the monitored link-state advertisement messages, and detecting an anomaly related to routing based on the feature vectors. In particular, detecting an anomaly related to routing includes feeding the feature vectors to a machine learning system, conveniently a one-class classifier, preferably a one-class support vector machine (OC-SVM).

摘要： Apparatus for monitoring operation of a processing system includes a set of modules for monitoring operation of a set of system primitives that allocate or release the system resources and are used by different processes running on the system. Preferably, the modules include at least one application knowledge module tracking the processes running on the system and monitoring the resources used thereby, a network knowledge module monitoring connections by the processes running on the system, a file-system analysis module monitoring the file-related operations performed within the system, and a device monitoring module monitoring operation of commonly used modules with the system. A preferred field of application is in host-based intrusion detection systems.

摘要： Packet flows are processed, e.g. to perform an intrusion detection function in a communication network, by means of a multiprocessor system including a plurality of processing units. The packets are distributed for processing among the processing units via a distribution function. Such a distribution function is selectively allotted to one of the processing units of the plurality. A preferred embodiment of the arrangement involves using a single Symmetric Multi-Processor machine with a single network port to Gigabit/sec link. The corresponding system architecture does not require any intermediate device, or any external load balancing mechanism. All the processing work is performed on a single system, which is able to dynamically balance the traffic load among the several independent CPUs. By resorting to a specific scheduling arrangement, such a system is able to effectively distribute the computations required to perform both the loadbalancing and the detection operations.
