ABSTRACT:
Apparatus and methods for intrusion protection in safety instrumented process control systems are disclosed. An example method of protecting a safety instrumented system includes receiving legitimate information from a component of a process control system wherein the legitimate information is intended for delivery to a safety instrumented system, determining if a signature at least substantially matches the legitimate information, and preventing the legitimate information from reaching the safety instrumented system when it is determined that the signature at least substantially matches the legitimate information.
