Summary
In this chapter, we have discussed the fundamental concepts that shape functional safety and ICS cybersecurity with a great emphasis on risk mitigation. We have covered the components, standards, terms, and practices that are currently used in multiple industries. Furthermore, we have examined the functional safety and cybersecurity life cycles, including their similarities and discrepancies.
We now have a strong foundation to dive more deeply into practical SIS cybersecurity. The next chapter will explore the need to protect safety processes against emerging cyber threats and will provide examples of recent security incidents that have primarily targeted SIS.
