In order to better combat cyberthreats to national security, the US Department of Defense is setting up shop in Silicon Valley. At a lecture today at Stanford University, Defense Secretary Ash Carter outlined the department's new focus on cyberdefense, including tapping into the ecosystem of Silicon Valley to drive innovation against cyber attacks against "US interests." Carter announced that he's setting up the Defense Innovation Unit X (X stands for Experimental) inside the DOD, staffed by active-duty and military personnel alongside reservists. "They'll strengthen existing relationships and build new ones; help scout for new technologies; and help function as a local interface for the department," Carter explained. "Down the road, they could help startups find new work to do with DOD."
