Abstract

This diploma thesis focuses on the automatic network traffic description using models of communication. The main aim is at industrial control system protocols, especially IEC 60870-5-104. We propose a method of characterizing the network state using both communication content and behavior in time viewpoints. These aspects are described using finite state automata, prefix trees, and recurrence analysis. In the second part of this thesis, we focus on the implementation of a program, which is capable to use the obtained model to verify network traffic in real-time.

Keywords

IEC 60870-5-104, TCP, SCADA, industrial control systems, network traffic analysis, system model, generic analysis, finite automaton, timed automaton, prefix tree, pattern recognition, pattern matching, periodicity, recurrence
