A method by a computing device implementing an attack analyzer for processing malicious events. The method includes determining a first set of features describing a malicious event detected by a firewall, determining a set of distances using a non-Euclidean distance function and the first set of features, wherein the non-Euclidean distance function is used to determine geographic origin similarity between different Internet Protocol addresses included in the first and second set of features, generating a statistical distribution object using the set of distances, wherein the statistical distribution object includes information describing a cluster that includes at least the malicious event and one or more other malicious events that are determined to be similar to the malicious event in terms of geographic origin, and transmitting information describing the cluster to a management console for presentation to an administrator on a graphical user interface.

Aggregating alerts of malicious events for computer security

A method of processing malicious events in a network infrastructure determines features of malicious events detected by a firewall of an attack analyzer. Example features may indicate an origin of an attack, a target of the attack, or a type of a malicious event. The attack analyzer determines distances, e.g., using a non-Euclidean distance function, between features of a given malicious event and features of statistical distribution objects (SDOs). The SDOs describe clusters of previously detected malicious events. The attack analyzer may select one of the SDOs that has features similar to those of the given malicious event. The attack analyzer can update the SDOs by including an alert of the given malicious event with an existing cluster or generating a new cluster including the alert. The attack analyzer may transmit information describing the clusters of the SDOs to a management console.
