Anomaly Management using Complex Event Processing

During the last decade, complex event processing (CEP) has emerged as a technological foundation for many time-critical monitoring applications. CEP is powerful, effective, easy to use and low in costs at the same time. Common CEP applications are for example stock-market analysis, detection of fraudulent credit card use, traffic monitoring and consumption forecasting in power grids. Many application domains are still hard to target by CEP, because state of the art CEP technology is characterized by a static behavior and by a signature-based detection paradigm. In this paper, we motivate substantial improvements of CEP technology by making the behavior of the infrastructure dynamic and by switching the detection paradigm from signatures to anomalies. This leads to multiple changes in the infrastructure that raise interesting and challenging research questions. The resulting dynamic CEP infrastructure not only makes existing applications more powerful and easier to maintain but also enables novel application domains.
