In last week's blog, Heather wrote an excellent summary of Mark Cooksley's network security presentation regarding "Why Industrial Networks are Different than IT Networks". In it she noted that the number one goal of ICS security is based on the concern for safety. This is spot-on in my opinion. However, there is more to consider when it comes to industrial security priorities…

Yesterday afternoon I received a note from another security expert that has left me a bit stunned. Like most of you, I assumed that if you are patching your Windows computers on your SCADA or ICS system (using some variation of Microsoft Windows Update), then any vulnerable services that can be patched will be patched. Well guess again – you may still have a number of open vulnerabilities that are happily being missed by the Windows update service.
