Report: DOD must embrace open-source software

The Defense Department increasingly relies on software for everything from weapons systems to accounting, but it is failing to capitalize on the power of open-source software, according to a report from the Center for a New American Security. In "Open Source Software and the Department of Defense," CNAS argues that a number of cultural factors, biases and regulatory barriers are keeping DOD from embracing open-source options. "Unfortunately, software development is not currently a high-profile, high-priority topic in the discussion about diminishing U.S. military technical superiority," the report states. "It should be."
