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.
Section 1. Principles Governing the Collection of Signals Intelligence.
Signals intelligence collection shall be authorized and conducted consistent with the following principles:

Executive Order 12333 further notes that "[i]ntelligence includes foreign intelligence and counterintelligence."

(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 advantage 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.
