Despite extensive research effort, ordinary anomaly detection systems still suffer from serious drawbacks such as high false alarm rates due to the enormous variety of network traffic. Also, increasingly fast network speeds pose performance problems to systems which base upon deep packet inspection. In this paper, we address these problems by proposing a novel inductive network intrusion detection system. The system operates on lightweight network flows and uses One-Class Support Vector Machines for analysis. In contrast to traditional anomaly detection systems, the system is trained with malicious rather than with benign network data. The system is suited for the load of large-scale networks and is less affected by typical problems of ordinary anomaly detection systems. Evaluations brought satisfying results which indicate that the proposed approach is interesting for further research and perfectly complements traditional signature-based intrusion detection systems.
