bariswheel writes "Alan Cox, fellow at Red Hat Linux, gives a short-and-sweet talk at the European OSCON on the The Next 50 Years of Computer Security. Implementations of modularity, Trusted Computing hardware, 'separation of secrets,' and overcoming the challenge of users not reading dialog boxes, will be crucial milestones as we head on to the future. He states: "As security improves, we need to keep building things which are usable, which are turned on by default, which means understanding users is the target for the next 50 years. You don't buy a car with optional bumpers. You can have a steering wheel fitted if you like, but it comes with a spike by default." All of this has to be shipped in a way that doesn't stop the user from doing things."
