Abstract. Securing control networks (e.g. for power and gas distribution) requires dedicated approaches. Sequence-aware intrusion detection models the network traffic under normal operation to identify malicious behavior. Unfortunately, such models are often large and difficult to handle. This paper proposes a method that generates smaller traffic models and discusses the accuracy of those reduced models in the context of a real control infrastructure employing the IEC 60870-5-104 protocol.
