chicksdaddy writes "The U.S. Department of Defense has stopped updating its main reference list of vital defense technologies that are banned from export, according to a new report from the Government Accountability Office (GAO), The Security Ledger reports. The Militarily Critical Technologies List (MCTL) is used to identify technologies that are critical to national defense and that require extra protection — including bans on exports and the application of anti-tamper technology. GAO warned six years ago that the Departments of State and Commerce, which are supposed to use the list, found it too broad and outdated to be of much use. The latest report (GAO 13-157) finds that the situation has worsened: budget cuts forced the DOD to largely stop updating and grooming the list in 2011. Sections on emerging technologies are outdated, while other sections haven't been updated since 1999. Without the list to rely on, the DOD has turned to a hodgepodge of other lists, while officials in the Departments of State and Commerce who are responsible for making decisions about whether to allow a particular technology to be exported have turned to ad-hoc networks of subject experts. Other agencies are looking into developing their own MCTL equivalents, potentially wasting government resources duplicating work that has already been done, GAO found."
