Hacking Safety Instrumented Systems
The increasing complexity of modern Industrial Control Systems (ICSs) has opened up the doors to a number of new and emerging cybersecurity threats. As seen in the case of TRITON, BlackEnergy, Destroyer, and Stuxnet, to name but a few, advanced cyber attacks have the very real ability to cause major disruption and damage.
In response to these incidents, the process industry has been called upon to take greater preventive actions to ensure the ongoing security of these critical assets. However, too often, these initiatives have been temporary and compliance-oriented – as such, they have not fully addressed many of the underlying security issues.
Therefore, in order to protect mission critical systems such as ICSs and Safety Instrumented Systems (SISs), it is essential to understand potential threats and vulnerabilities associated with both. This chapter will examine various attack strategies employed by malicious actors, in the process...
