The folks running the annual RSA Conference this week will tell you that the show is bigger than ever and security is at the top of every CIO's list of concerns. But if heavyweights such as Sun Microsystems, Cisco Systems, and Microsoft have their way, enterprises soon will have little use for the wares that most of the security vendors are hawking. It's rare that those three vendors would all agree on anything, but in speeches and interviews this week, executives from all of them have said that it's time to build security into hardware and software from the ground up and stop trying to fix problems after the fact.
