The Importance of Safety Instrumented Systems in Chemical Plants

A mysterious mechanical failure one fateful night in a Saudi Arabian chemical plant leads a cast of operational technology researchers down a strange path towards an uncommon, but grave, threat. In this episode, we hear how these researchers discovered this threat and tried to identify who was responsible for the malware behind it. We also consider how this kind of attack may pose a threat to human life wherever there are manufacturing or public infrastructure facilities around the world.
