Presidential Policy Directive on Signals Intelligence Activities

The United States, like other nations, has gathered intelligence throughout its history to ensure that national security and foreign policy decisionmakers have access to timely, accurate, and insightful information. The collection of signals intelligence is necessary for the United States to advance its national security and foreign policy interests and to protect its citizens and the citizens of its allies and partners from harm. At the same time, signals intelligence activities and the possibility that such activities may be improperly disclosed to the public pose multiple risks. These include risks to: our relationships with other nations, including the cooperation we receive from other nations on law enforcement, counterterrorism, and other issues; our commercial, economic, and financial interests, including a potential loss of international trust in U.S. firms and the decreased willingness of other nations to participate in international data sharing, privacy, and regulatory regimes; the credibility of our commitment to an open, interoperable, and secure global Internet; and the protection of intelligence sources and methods. In addition, our signals intelligence activities must take into account that all persons should be treated with dignity and respect, regardless of their nationality or wherever they might reside, and that all persons have legitimate privacy interests in the handling of their personal information. In determining why, whether, when, and how the United States conducts signals intelligence activities, we must weigh all of these considerations in a context in which information and communications technologies are constantly changing. The evolution of technology has created a world where communications important to our national security and the communications all of us make as part of our daily lives are transmitted through the same channels. This presents new and diverse opportunities for, and challenges with respect to, the collection of intelligence – and especially signals intelligence. The United States Intelligence Community (IC) has achieved remarkable success in developing enhanced capabilities to perform its signals intelligence mission in this rapidly changing world, and these enhanced capabilities are a major reason we have been able to adapt to a dynamic and challenging security environment. The United States must preserve and continue to develop a robust and technologically advanced signals intelligence capability to protect our security and that of our partners and allies. Our signals intelligence capabilities must also be agile enough to enable us to focus on fleeting opportunities or emerging crises and to address not only the issues of today, but also the issues of tomorrow, which we may not be able to foresee. Advanced technologies can increase risks, as well as opportunities, however, and we must consider these risks when deploying our signals intelligence capabilities. The IC conducts signals intelligence activities with care and precision to ensure that its collection, retention, use, and dissemination of signals intelligence account for these risks. In light of the evolving technological and geopolitical environment, we must continue to ensure that our signals intelligence policies and practices appropriately take into account our alliances and other partnerships; the leadership role that the United States plays in upholding democratic principles and universal human rights; the increased globalization of trade, investment, and information flows; our commitment to an open, interoperable and secure global Internet; and the legitimate privacy and civil liberties concerns of U.S. citizens and citizens of other nations. Presidents have long directed the acquisition of foreign intelligence and counterintelligence pursuant to their constitutional authority to conduct U.S. foreign relations and to fulfill their constitutional responsibilities as Commander in Chief and Chief Executive. They have also provided direction on the conduct of intelligence activities in furtherance of these authorities and responsibilities, as well as in execution of laws enacted by the Congress. Consistent with this historical practice, this directive articulates principles to guide why, whether, when, and how the United States conducts signals intelligence activities for authorized foreign intelligence and counterintelligence purposes.
