Information Environment: Opportunities and Threats to DOD's National Security Mission, Report to Congressional Addressees [open pdf - 8MB]
From the Highlights: "Today's information environment poses new and complex challenges for national security as the world has shifted from an industrial age to an information age. Advances in information technology, wireless communications, and social media have increased the speed and range of information, diffused power over information, and shifted socio-cultural norms. The United States' competitors and adversaries are taking advantage of these advances and the subsequent effects in the information environment to offset the U.S.'s conventional warfighting advantages. [...] To illustrate and better inform Congress and DOD officials, this report describes DOD's use and protection of the information environment through the following six key elements--ubiquitous and malign information, effects on DOD's mission, threat actors, threat actions, institutional challenges, and emerging technologies that can enable or adversely affect DOD's missions. This report also describes DOD actions taken and planned to use and protect the information environment."
