How can I reliably and easily secure my control system?

A lot of people are re-examining this question and giving it higher priority after learning about Stuxnet and the recent publishing of SCADA system vulnerabilities on the Internet.  It is no longer possible to believe that ‘air gaps’ between your systems and the rest of the world, or that ‘security by obscurity’ are effective security strategies.

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.
