Cyber Security in Industrial Control Systems and SCADA Applications: Modbus TCP Protocol Example
Journal Title: Gazi Üniversitesi Fen Bilimleri Dergisi Part C: Tasarım ve Teknoloji - Year 2018, Vol 6, Issue 1
Abstract
Electrical energy generation, transmission and distribution systems are evaluated in terms of national security dimension and defined as critical infrastructures. Monitoring and controlling of these systems are provided by Industrial Control Systems (ICS) or Supervisory Control and Data Acquisition (SCADA) systems. According to the latest advances in communication and internet technology, ICS/SCADA systems have started to become integrated with these systems. As a result of this situation, current or existing vulnerabilities in information and communication technology affect SCADA systems directly. Therefore, this paper focuses on the cyber security of ICS/SCADA systems. It has been proved that the lack of authentication detected in Modbus TCP protocol, one of the most used in ICS/SCADA systems, can be exploited. In order to solve this security issue, a software is developed using the Python programming language for blocking or mitigating the cyber attacks. The proposed solution is subjected to several tests and results show that the attacks can be prevented successfully. Thus, it is considered that the proposed work will contribute to the security of ICS/SCADA systems and the industrial protocols used for communicating these systems.
