Intrusion Detection System Based on a Deterministic Finite Automaton for Smart Grid Systems
Smart grid system is a target to many types of network attacks, such as Denial Of Serive (DOS), Man In The Middle (MITM) ... that could compromise users’ privacy and network’s integrity and availability. For this reason we developed a network based intrusion detection system (IDS) that relies on a deterministic finite automaton (DFA) to recognize an attack’s language that represents some of the attacks that can target the smart grid network. The attacks’ language is defined using elements or symbols that help identifying each type of attack. Results of our simulations show the efficiency of our IDS and its ability to detect dangerous cyber attacks.
