There is a post on securiosis that I think sums up the future of Information Security quite nicely.
In the past information was very structured because of disk space issues. Then Moores law kicked in and information got messier and less structured over time.
Now because of Information Security needs the information has to become tidier and more structured again. But now I think we have tools like XML that will allow us to be able to clean up our mess and be more secure and more productive while not being totally restrictive.
It is a very interesting time and I call it Security 2.0 (even though this term is already used by the likes of Gartner and such.)
