These are the two longest running energy + cybersecurity conference tracks in North America and both have summits coming up this Fall:
Sep 25-18, 2012
Oct 22-24, 2012
San Francisco, CA
Click through and you'll see that both agendas are forming and speaker rosters are still being firmed up, but utility participation is on the rise and these are the real deal.
Also there's much more focus now on the security of operational systems, not just IT/Business.
Recommend you attend one of these, and if you can't, then at least pay attention to the articles, blogs and videos that come out of them ... some, hopefully, right here.
