Tofino OPC Enforcer

When you hear the words “defense–in-depth” do you immediately think of layers of firewalls?

If so, you are not alone – most of us immediately think of security concepts in traditional physical security terms.  For example, we imagine “more defense” as being more moats and castle walls around the crown jewels.  But that is not the only way (or even the best way) to create secure ICS or SCADA systems.

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.
