CISA has been championing Secure by Design principles. Many of the principles are universal, like adopting MFA and having opinionated defaults that reduce the need for hardening guides. Matthew Rogers talks about how the approach to Secure by Design has to be tailored for Operational Technology (OT) systems. These systems have strict requirements on safety and many of them rely on protocols that are four (or more!) decades old. He explains how the considerations in this space go far beyond just memory safety concerns.
