The Issue of Adaptation of Diagnostic System to Protect Industrial Control Systems Against Cyber Threads

Abstract

The paper discusses issues related to the adaptation of diagnostic systems to the protection of industrial control systems (ICS) against cyber threats. Typical methods of attacking industrial systems are presented, along with a brief description of exemplary attacks. The potential consequences of attacks on both the operation of supervised industrial installations and the behaviour of operators were also discussed. The vulnerabilities of industrial control systems to attacks have been demonstrated, while the differences between them and typical IT systems were highlighted. Three main groups of ICS protection methods are discussed, their strengths and weaknesses were presented. An important part of the paper is the proposal to change the structure of the diagnostic system so that it would be able to better detect and distinguish between attacks and faults.
