re: Firefighters See Problems, CIOs Must See Opportunities
With regards to your security point - I think one thing that needs to be addressed is the valuation of the informational assets that the organization possesses. Sure, it's possible to build a Fort Knox to protect your data, but does it make sense to spend millions of dollars pursuing that dream when your informational assets don't match that value? Every dollar spent gets scrutinized these days, since dollars are in short supply.
When it comes to innovation - until there is zero possibility of any form of threat out there and every system is built with zero single points of failure, there will always be the need for a react and defend group in any organization's IT department. They key is to reduce the time spent on reacting and defending in order to improve the organization.
I also see the Social Media point playing into the security point by way of social engineering.
