M0812 Safety Instrumented Systems

Utilize Safety Instrumented Systems (SIS) to provide an additional layer of protection to hazard scenarios that may cause property damage. A SIS will typically include sensors, logic solvers, and a final control element that can be used to automatically respond to an hazardous condition 1 . Ensure that all SISs are segmented from operational networks to prevent them from being targeted by additional adversarial behavior.
