The Latest in IT Security

The Defense Advanced Research Projects Agency, or DARPA, has envisioned some peculiar and diverse projects over the years, from molten metal-filled missiles, all the way to submarines that can fly. The group suggested the idea, which is nicknamed Block Access to Deny Entry (BlockADE), in a request for information that was spotted by io9. In short, it asks for a way to construct a barrier without human intervention, meaning no touching anything. You just hit a button, or pull a tab and it should expand into a barrier that DARPA says would be orders of magnitude in size. Better yet, DARPA suggests it could offer resistance from ballistic devices (like bullets or rockets), be see-through, and be reversible back down to a smaller state if need be.
