SIS Evolution and Trends

The use of Safety-Instrumented Systems (SISs) has long played an important role in the critical processes of industrial facilities and military operations, and for decades, their use has extended to other sectors. This widespread adoption has seen SIS technology evolve in tandem with rapid technological advancements, from analog and serial systems right up to the currently implemented fully digital Ethernet-based systems that are now commonplace and widely implemented.

However, as technologies have progressed and evolved, new cyber risks and challenges have also developed, placing many of the technologies that we are now so deeply reliant upon under great threat.

This chapter will comprehensively explore the history, evolution, and current state of SISs in order to help you gain a better understanding of the need for protection against cyber risks. We will examine various Industrial Control System (ICS) cyber risk trends and their evolution, as well as...
