Report of the Defense Science Board Task Force on Mission Impact of Foreign Influence on DoD Software [open pdf - 2MB]
"Software has become the central ingredient of the information age, increasing productivity, facilitating the storage and transfer of information, and enabling functionality in almost every realm of human endeavor. However, as it improves the Department of Defense's (DoD) capability, it increases DoDs dependency. Each year the Department of Defense depends more on software for it administration and for the planning and execution of its missions. This growing dependency is a source of weakness exacerbated by the mounting size, complexity and interconnectedness of its software programs. It is only a matter of time before an adversary exploits this weakness at a critical moment in history. The software industry has become increasingly and irrevocably global. Much of the code is now written outside the United States (U.S.), some in countries that may have interests inimical to those of the United States. The combination of DoDs profound and growing dependence upon software and the expanding opportunity for adversaries to introduce malicious code into this software has led to a growing risk to the Nation's defense."
