Detection of Intrusion Using Alert Aggregation in DataStream Modelling With Constructive Basis

Alert aggregation is an important subtask of intrusion detection. The goal is to identify and to cluster different alerts - produced by low-level intrusion detection systems, firewalls, etc. - belonging to a specific attack instance which has been initiated by an attacker at a certain point in time. Thus, meta-alerts can be generated for the clusters that contain all the relevant information whereas the amount of data (i.e., alerts) can be reduced substantially. Meta-alerts may then be the basis for reporting to security experts or for communication within a distributed intrusion detection system.
