Cybersecurity of SCADA Systems from Critical Infrastructure Aspect 1

Abstract

Today, as technological advances continue, the role of cybersecurity is becoming increasingly important, as both individuals and companies need to keep up with the evolution of cyberattacks – in terms of both, their number and their methods. Industrial facilities and critical systems, of which SCADA systems are a key component, are prime targets for these attacks. In this context, these installations require a much higher level of protection than the average due to their role. In the first part of the article, the author describes the basic concepts of SCADA systems, as well as the specifications and good practices required for
their installation and operation. It also describes past and current cybersecurity challenges, both general and SCADA system-focused, based on attack method, year of attack, and classification of the sector involved.
