Summary
In conclusion, there are multiple ways you can secure your organization holistically (IT, OT, the IoT, and the IIoT). In this chapter, you have seen the evolution and adoption of Industry 4.0 and how it has affected the cybersecurity landscape of IoT/OT devices. There are multiple approaches to adopting secure practices for the IoT or OT that organizations can take, and we have discussed some of the best approaches. To top it off, you can always look at defense in depth to ensure you have a backup security mechanism and are covered in the case of any failures.
In the next chapter, we will look at the network architecture of IoT/OT devices and how this affects cybersecurity when it is not managed well.
