Abstract: - The essential subtask of intrusion detection is Alert aggregation. Protecting our data in the internet is a great risk. Intruders and hackers are always ready grab our data. To identify unauthorized users and to cluster different alerts produced by low-level intrusion detection systems firewalls, Intrusion detection system has been introduced. The relevant information whereas the amount of data can be reduced substantially by Meta-alters which will be generated for the clusters. At a certain point in time which has been initiated by an attacker is belonging to a specific hacking. For communication within a distributed intrusion detection system the meta-alerts may be the basis for reporting to security experts. In this paper, for online alert aggregation we propose a novel technique which is based on a dynamic and probabilistic model of current attack situation. For the estimation of the model parameters, it can be regarded as a data stream version of a maximum likelihood approach. The first alerts, which are belonging to a new attack instance, are generated with meta-alerts with a delay of typically only a few seconds. To achieve Reduction rates while the number of missing meta-alerts is extremely low can be possible with the three benchmark data sets are demonstrated.
