This December 2020 eBook was published by Automation.com, a subsidiary of the International Society of Automation. It examines emerging cyberthreats—in particular, the misuse of DNS protocols—and sets out a “zero-trust” cybersecurity approach that should work within Operational Technology (OT), industrial control systems (ICS), and supervisory control and data acquisition (SCADA). There are key takeaways on the value of open and secure SCADA systems, safety best practices for improving OT cybersecurity, and how to strategically communicate cybersecurity information to corporate board members.
