Fixed Configuration Firewall

In my last blog, I mentioned that one of the good things about Invensys winning the Breakthrough Product of the Year Award for 2010 for the Triconex Tofino OPC Firewall was that it may indicate that industrial network security for control and SCADA systems is becoming mainstream in the engineering world.

Earlier this week Patrick Coyle wrote an excellent blog on Safety Integrated Systems (SIS) and why they are so important to safe industrial operations. If you are new to the SCADA and ICS world, or if you have mostly worked on non-safety related processes, I highly recommend you read his blog.
