State exchange computer systems could be open to back-door security vulnerabilities, the Associated Press reported. States needed approval to connect to the new federal data hub, but AP-procured documents showed federal officials were signing security approvals regardless of whether state computer systems had a high risk for security problems. In fact, more than two-thirds of state systems that were supposed to connect to federal computers to verify sensitive personal information, including income, immigration status and Social Security numbers, initially received a "high risk" rating. The Obama administration said it either resolved or is addressing the security problems cited. Article
