Abstract:
A security monitoring system processes event messages related to computer network security in real time, evaluating inter-event constraints so as to identify combinations of events that are partial solutions to a predefined event correlation rule, and furthermore evaluating combinations of the partial solutions do determine if they together satisfy the predefined event correlation rule. A decision tree is formed based on the rule. Event messages are categorized into groups at leaf nodes of the tree in accordance with a plurality of intra-event constraints, and then the messages are correlated in accordance with a plurality of inter-event constraints at non-leaf nodes of the tree. When the inter-event constraint at a root node of the tree has been satisfied, a network attack alert is issued and protective actions may be taken.
