Directive on Signals Intelligence Activities

Presidential Policy Directive/PPD-28

Subject: 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.¹The 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 counterintelligence² 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.³

Section 1. Principles Governing the Collection of Signals Intelligence.

Signals intelligence collection shall be authorized and conducted consistent with the following principles:

(a) The collection of signals intelligence shall be authorized by statute or Executive Order, proclamation, or other Presidential directive, and undertaken in accordance with the Constitution and applicable statutes, Executive Orders, proclamations, and Presidential directives.

(b) Privacy and civil liberties shall be integral considerations in the planning of U.S. signals intelligence activities. The United States shall not collect signals intelligence for the purpose of suppressing or burdening criticism or dissent, or for disadvantaging persons based on their ethnicity, race, gender, sexual orientation, or religion. Signals intelligence shall be collected exclusively where there is a foreign intelligence or counterintelligence purpose to support national and departmental missions and not for any other purposes.

(c) The collection of foreign private commercial information or trade secrets is authorized only to protect the national security of the United States or its partners and allies. It is not an authorized foreign intelligence or counterintelligence purpose to collect such information to afford a competitive advantage⁴ to U.S. companies and U.S. business sectors commercially.

(d) Signals intelligence activities shall be as tailored as feasible. In determining whether to collect signals intelligence, the United States shall consider the availability of other information, including from diplomatic and public sources. Such appropriate and feasible alternatives to signals intelligence should be prioritized.

Sec. 2. Limitations on the Use of Signals Intelligence Collected in Bulk.

Locating new or emerging threats and other vital national security information is difficult, as such information is often hidden within the large and complex system of modern global communications. The United States must consequently collect signals intelligence in bulk⁵ in certain circumstances in order to identify these threats. Routine communications and communications of national security interest increasingly transit the same networks, however, and the collection of signals intelligence in bulk may consequently result in the collection of information about persons whose activities are not of foreign intelligence or counterintelligence value. The United States will therefore impose new limits on its use of signals intelligence collected in bulk. These limits are intended to protect the privacy and civil liberties of all persons, whatever their nationality and regardless of where they might reside.

In particular, when the United States collects nonpublicly available signals intelligence in bulk, it shall use that data only for the purposes of detecting and countering: (1) espionage and other threats and activities directed by foreign powers or their intelligence services against the United States and its interests; (2) threats to the United States and its interests from terrorism; (3) threats to the United States and its interests from the development, possession, proliferation, or use of weapons of mass destruction; (4) cybersecurity threats; (5) threats to U.S. or allied Armed Forces or other U.S or allied personnel; and (6) transnational criminal threats, including illicit finance and sanctions evasion related to the other purposes named in this section. In no event may signals intelligence collected in bulk be used for the purpose of suppressing or burdening criticism or dissent; disadvantaging persons based on their ethnicity, race, gender, sexual orientation, or religion; affording a competitive advantage to U.S. companies and U.S. business sectors commercially; or achieving any purpose other than those identified in this section.

The Assistant to the President and National Security Advisor (APNSA), in consultation with the Director of National Intelligence (DNI), shall coordinate, on at least an annual basis, a review of the permissible uses of signals intelligence collected in bulk through the National Security Council Principals and Deputies Committee system identified in PPD-1 or any successor document. At the end of this review, I will be presented with recommended additions to or removals from the list of the permissible uses of signals intelligence collected in bulk.

The DNI shall maintain a list of the permissible uses of signals intelligence collected in bulk. This list shall be updated as necessary and made publicly available to the maximum extent feasible, consistent with the national security.

Sec. 3. Refining the Process for Collecting Signals Intelligence.

U.S. intelligence collection activities present the potential for national security damage if improperly disclosed. Signals intelligence collection raises special concerns, given the opportunities and risks created by the constantly evolving technological and geopolitical environment; the unique nature of such collection and the inherent concerns raised when signals intelligence can only be collected in bulk; and the risk of damage to our national security interests and our law enforcement, intelligence-sharing, and diplomatic relationships should our capabilities or activities be compromised. It is, therefore, essential that national security policymakers consider carefully the value of signals intelligence activities in light of the risks entailed in conducting these activities.

To enable this judgment, the heads of departments and agencies that participate in the policy processes for establishing signals intelligence priorities and requirements shall, on an annual basis, review any priorities or requirements identified by their departments or agencies and advise the DNI whether each should be maintained, with a copy of the advice provided to the APNSA.

Additionally, the classified Annex to this directive, which supplements the existing policy process for reviewing signals intelligence activities, affirms that determinations about whether and how to conduct signals intelligence activities must carefully evaluate the benefits to our national interests and the risks posed by those activities.⁶

Sec. 4. Safeguarding Personal Information Collected Through Signals Intelligence.

All persons should be treated with dignity and respect, regardless of their nationality or wherever they might reside, and all persons have legitimate privacy interests in the handling of their personal information.⁷ U.S. signals intelligence activities must, therefore, include appropriate safeguards for the personal information of all individuals, regardless of the nationality of the individual to whom the information pertains or where that individual resides.⁸

Policies and Procedures. The DNI, in consultation with the Attorney General, shall ensure that all elements of the IC establish policies and procedures that apply the following principles for safeguarding personal information collected from signals intelligence activities. To the maximum extent feasible consistent with the national security, these policies and procedures are to be applied equally to the personal information of all persons, regardless of nationality:⁹

i. Minimization. The sharing of intelligence that contains personal information is necessary to protect our national security and advance our foreign policy interests, as it enables the United States to coordinate activities across our government. At the same time, however, by setting appropriate limits on such sharing, the United States takes legitimate privacy concerns into account and decreases the risks that personal information will be misused or mishandled. Relatedly, the significance to our national security of intelligence is not always apparent upon an initial review of information: intelligence must be retained for a sufficient period of time for the IC to understand its relevance and use it to meet our national security needs. However, long-term storage of personal information unnecessary to protect our national security is inefficient, unnecessary, and raises legitimate privacy concerns. Accordingly, IC elements shall establish policies and procedures reasonably designed to minimize the dissemination and retention of personal information collected from signals intelligence activities.

• Dissemination: Personal information shall be disseminated only if the dissemination of comparable information concerning U.S. persons would be permitted under section 2.3 of Executive Order 12333.

• Retention: Personal information shall be retained only if the retention of comparable information concerning U.S. persons would be permitted under section 2.3 of Executive Order 12333 and shall be subject to the same retention periods as applied to comparable information concerning U.S. persons. Information for which no such determination has been made shall not be retained for more than 5 years, unless the DNI expressly determines that continued retention is in the national security interests of the United States.

Additionally, within 180 days of the date of this directive, the DNI, in coordination with the Attorney General, the heads of other elements of the IC, and the heads of departments and agencies containing other elements of the IC, shall prepare a report evaluating possible additional dissemination and retention safeguards for personal information collected through signals intelligence, consistent with technical capabilities and operational needs.

ii. Data Security and Access. When our national security and foreign policy needs require us to retain certain intelligence, it is vital that the United States take appropriate steps to ensure that any personal information contained within that intelligence is secure. Accordingly, personal information shall be processed and stored under conditions that provide adequate protection and prevent access by unauthorized persons, consistent with the applicable safeguards for sensitive information contained in relevant Executive Orders, proclamations, Presidential directives, IC directives, and associated policies. Access to such personal information shall be limited to authorized personnel with a need to know the information to perform their mission, consistent with the personnel security requirements of relevant Executive Orders, IC directives, and associated policies. Such personnel will be provided appropriate and adequate training in the principles set forth in this directive. These persons may access and use the information consistent with applicable laws and Executive Orders and the principles of this directive; personal information for which no determination has been made that it can be permissibly disseminated or retained under section 4(a)(i) of this directive shall be accessed only in order to make such determinations (or to conduct authorized administrative, security, and oversight functions).

iii. Data Quality. IC elements strive to provide national security policymakers with timely, accurate, and insightful intelligence, and inaccurate records and reporting can not only undermine our national security interests, but also can result in the collection or analysis of information relating to persons whose activities are not of foreign intelligence or counterintelligence value. Accordingly, personal information shall be included in intelligence products only as consistent with applicable IC standards for accuracy and objectivity, as set forth in relevant IC directives. Moreover, while IC elements should apply the IC Analytic Standards as a whole, particular care should be taken to apply standards relating to the quality and reliability of the information, consideration of alternative sources of information and interpretations of data, and objectivity in performing analysis.

iv. Oversight. The IC has long recognized that effective oversight is necessary to ensure that we are protecting our national security in a manner consistent with our interests and values. Accordingly, the policies and procedures of IC elements, and departments and agencies containing IC elements, shall include appropriate measures to facilitate oversight over the implementation of safeguards protecting personal information, to include periodic auditing against the standards required by this section.

The policies and procedures shall also recognize and facilitate the performance of oversight by the Inspectors General of IC elements, and departments and agencies containing IC elements, and other relevant oversight entities, as appropriate and consistent with their responsibilities. When a significant compliance issue occurs involving personal information of any person, regardless of nationality, collected as a result of signals intelligence activities, the issue shall, in addition to any existing reporting requirements, be reported promptly to the DNI, who shall determine what, if any, corrective actions are necessary. If the issue involves a non-United States person, the DNI, in consultation with the Secretary of State and the head of the notifying department or agency, shall determine whether steps should be taken to notify the relevant foreign government, consistent with the protection of sources and methods and of U.S. personnel.

(b) Update and Publication. Within 1 year of the date of this directive, IC elements shall update or issue new policies and procedures as necessary to implement section 4 of this directive, in coordination with the DNI. To enhance public understanding of, and promote public trust in, the safeguards in place to protect personal information, these updated or newly issued policies and procedures shall be publicly released to the maximum extent possible, consistent with classification requirements.

(c) Privacy and Civil Liberties Policy Official. To help ensure that the legitimate privacy interests all people share related to the handling of their personal information are appropriately considered in light of the principles in this section, the APNSA, the Director of the Office of Management and Budget (OMB), and the Director of the Office of Science and Technology Policy (OSTP) shall identify one or more senior officials who will be responsible for working with the DNI, the Attorney General, the heads of other elements of the IC, and the heads of departments and agencies containing other elements of the IC, as appropriate, as they develop the policies and procedures called for in this section.

(d) Coordinator for International Diplomacy. The Secretary of State shall identify a senior official within the Department of State to coordinate with the responsible departments and agencies the United States Government's diplomatic and foreign policy efforts related to international information technology issues and to serve as a point of contact for foreign governments who wish to raise concerns regarding signals intelligence activities conducted by the United States.

Sec. 5. Reports.

(a) Within 180 days of the date of this directive, the DNI shall provide a status report that updates me on the progress of the IC's implementation of section 4 of this directive.

(b) The Privacy and Civil Liberties Oversight Board is encouraged to provide me with a report that assesses the implementation of any matters contained within this directive that fall within its mandate.

(c) Within 120 days of the date of this directive, the President's Intelligence Advisory Board shall provide me with a report identifying options for assessing the distinction between metadata and other types of information, and for replacing the "need-to-share" or "need-to-know" models for classified information sharing with a Work-Related Access model.

(d) Within 1 year of the date of this directive, the DNI, in coordination with the heads of relevant elements of the IC and OSTP, shall provide me with a report assessing the feasibility of creating software that would allow the IC more easily to conduct targeted information acquisition rather than bulk collection.

Sec. 6. General Provisions.

(a) Nothing in this directive shall be construed to prevent me from exercising my constitutional authority, including as Commander in Chief, Chief Executive, and in the conduct of foreign affairs, as well as my statutory authority. Consistent with this principle, a recipient of this directive may at any time recommend to me, through the APNSA, a change to the policies and procedures contained in this directive.

(b) Nothing in this directive shall be construed to impair or otherwise affect the authority or responsibility granted by law to a United States Government department or agency, or the head thereof, or the functions of the Director of OMB relating to budgetary, administrative, or legislative proposals. This directive is intended to supplement existing processes or procedures for reviewing foreign intelligence or counterintelligence activities and should not be read to supersede such processes and procedures unless explicitly stated.

(c) This directive shall be implemented consistent with applicable U.S. law and subject to the availability of appropriations.

(d) This directive is not intended to, and does not, create any right or benefit, substantive or procedural, enforceable at law or in equity by any party against the United States, its departments, agencies, or entities, its officers, employees, or agents, or any other person.
