Network coding has recently attracted attention as a substantial improvement to packet retransmission schemes in wireless multicast broadcast services (MBS). Since the problem of finding the optimal network code maximizing the bandwidth efficiency is hard to solve and hard to approximate, two main network coding heuristic schemes, namely opportunistic and full network coding, were suggested […]
Online Intrusion Alert Aggregation with Generative Data Stream Modeling
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 […]
