NASA’s security troubles shouldn’t surprise you. The signs of trouble were in place when I interviewed one of the agency’s IT guys five years ago. He spoke of a decentralized and fragmented network without much interfacing or centralization of systems from one division to the next. NASA ramped up its security efforts in the following years, but I always wondered if it would be enough. Six NASA servers exposed to the Internet had critical vulnerabilities that could have endangered Space Shuttle, International Space Station and Hubble Telescope missions.”]
