Safety Via Security
Safety is important in any industrial environment, but in some industries special precautions must be followed to ensure ongoing safe operation. Many sites use a Safety Instrumentation System (SIS) to monitor the plant process and override the control system if critical parameters go outside of normal limits.
The same thing can happen to your SIS. What steps have you taken to protect it?
The conclusion is unavoidable: secure functioning requires cyber security. Because of this, your network design should specifically safeguard your Safety Instrumentation System (SIS) by separating it into a network security zone and using the Laude Security Appliance to ward off threats to that zone.
