Authorities

Under Section 702 of the FISA, NSA is authorized to target non-U.S. persons who are reasonably believed to be located outside the United States. The principal application of this authority is in the collection of communications by foreign persons that utilize U.S. communications service providers. The United States is a principal hub in the world's telecommunications system and FISA is designed to allow the U.S. Government to acquire foreign intelligence while protecting the civil liberties and privacy of Americans. In general, Section 702 authorizes the Attorney General and Director of National Intelligence to make and submit to the FISA Court written certifications for the purpose of acquiring foreign intelligence information. Upon the issuance of an order by the FISA Court approving such a certification and the use of targeting and minimization procedures, the Attorney General and Director of National Intelligence may jointly authorize for up to one year the targeting of non-United States persons reasonably believed to be located overseas to acquire foreign intelligence information. The collection is acquired through compelled assistance from relevant electronic communications service providers.

NSA provides specific identifiers (for example, e-mail addresses, telephone numbers) used by non-U.S. persons overseas who the government believes possess, communicate, or are likely to receive foreign intelligence information authorized for collection under an approved certification. Once approved, those identifiers are used to select communications for acquisition. Service providers are compelled to assist NSA in acquiring the communications associated with those identifiers.
For a variety of reasons, including technical ones, the communications of U.S. persons are sometimes incidentally acquired in targeting the foreign entities. For example, a U.S. person might be courtesy copied on an e-mail to or from a legitimate foreign target, or a person in the U.S. might be in contact with a known terrorist target. In those cases, minimization procedures adopted by the Attorney General in consultation with the Director of National Intelligence and approved by the Foreign Intelligence Surveillance Court are used to protect the privacy of the U.S. person. These minimization procedures control the acquisition, retention, and dissemination of any U.S. person information incidentally acquired during operations conducted pursuant to Section 702.

The collection under FAA Section 702 is the most significant tool in the NSA collection arsenal for the detection, identification, and disruption of terrorist threats to the U.S. and around the world. One notable example is the Najibullah Zazi case. In early September 2009, while monitoring the activities of al Qaeda terrorists in Pakistan, NSA noted contact from an individual in the U.S. that the FBI subsequently identified as Colorado-based Najibullah Zazi. The U.S. Intelligence Community, including the FBI and NSA, worked in concert to determine his relationship with al Qaeda, as well as identify any foreign or domestic terrorist links. The FBI tracked Zazi as he traveled to New York to meet with co-conspirators, where they were planning to conduct a terrorist attack. Zazi and his co-conspirators were subsequently arrested. Zazi pled guilty to conspiring to bomb the New York City subway system. The FAA Section 702 collection against foreign terrorists was critical to the discovery and disruption of this threat to the U.S.

NSA relies on Title I of FISA to conduct electronic surveillance of foreign powers or their agents, to include members of international terrorist organizations. Except for certain narrow exceptions specified in FISA, a specific court order from the Foreign Intelligence Surveillance Court based on a showing of probable cause is required for this type of collection.

There are three additional FISA authorities that NSA relies on, after gaining court approval, that involve the acquisition of communications, or information about communications, of U.S. persons for foreign intelligence purposes on which additional focus is appropriate. These are the Business Records FISA provision in Section 501 (also known by its section numbering within the PATRIOT Act as Section 215) and Sections 704 and 705(b) of the FISA.

Under NSA's Business Records FISA program (or BR FISA), first approved by the Foreign Intelligence Surveillance Court (FISC) in 2006 and subsequently reauthorized during two different Administrations, four different Congresses, and by 14 federal judges, specified U.S. telecommunications providers are compelled by court order to provide NSA with information about telephone calls to, from, or within the U.S. The information is known as metadata, and consists of information such as the called and calling telephone numbers and the date, time, and duration of the call - but no user identification, content, or cell site locational data. The purpose of this particular collection is to identify the U.S. nexus of a foreign terrorist threat to the homeland.

The Government cannot conduct substantive queries of the bulk records for any purpose other than counterterrorism. Under the FISC orders authorizing the collection, authorized queries may only begin with an "identifier," such as a telephone number, that is associated with one of the foreign terrorist organizations that was previously identified to and approved by the Court. An identifier used to commence a query of the data is referred to as a "seed." Specifically, under Court-approved rules applicable to the program, there must be a "reasonable, articulable suspicion" that a seed identifier used to query the data for foreign intelligence purposes is associated with a particular foreign terrorist organization. When the seed identifier is reasonably believed to be used by a U.S. person, the suspicion of an association with a particular foreign terrorist organization cannot be based solely on activities protected by the First Amendment. The "reasonable, articulable suspicion" requirement protects against the indiscriminate querying of the collected data. Technical controls preclude NSA analysts from seeing any metadata unless it is the result of a query using an approved identifier.

The BR FISA program is used in cases where there is believed to be a threat to the homeland. Of the 54 terrorism events recently discussed in public, 13 of them had a homeland nexus, and in 12 of those cases, BR FISA played a role. Every search into the BR FISA database is auditable and all three branches of our government exercise oversight over NSA's use of this authority.

FISA Section 704 authorizes the targeting of a U.S. person outside the U.S. for foreign intelligence purposes if there is probable cause to believe the U.S. person is a foreign power or is an officer, employee, or agent of a foreign power. This requires a specific, individual court order by the Foreign Intelligence Surveillance Court. The collection must be conducted using techniques not otherwise regulated by FISA.

Section 705(b) permits the Attorney General to approve similar collection against a U.S. person who is already the subject of a FISA court order obtained pursuant to Section 105 or 304 of FISA. The probable cause standard has, in these cases, already been met through the FISA court order process.

According to figures published by a major tech provider, the Internet carries 1,826 Petabytes of information per day. In its foreign intelligence mission, NSA touches about 1.6% of that. However, of the 1.6% of the data, only 0.025% is actually selected for review. The net effect is that NSA analysts look at 0.00004% of the world's traffic in conducting their mission - that's less than one part in a million. Put another way, if a standard basketball court represented the global communications environment, NSA's total collection would be represented by an area smaller than a dime on that basketball court.

Under all FISA and FAA programs, the government compels one or more providers to assist NSA with the collection of information responsive to the foreign intelligence need. The government employs covernames to describe its collection by source. Some that have been revealed in the press recently include FAIRVIEW, BLARNEY, OAKSTAR, and LITHIUM. While some have tried to characterize the involvement of such providers as separate programs, that is not accurate. The role of providers compelled to provide assistance by the FISC is identified separately by the Government as a specific facet of the lawful collection activity.

NSA partners with well over 30 different nations in order to conduct its foreign intelligence mission. In every case, NSA does not and will not use a relationship with a foreign intelligence service to ask that service to do what NSA is itself prohibited by law from doing. These partnerships are an important part of the U.S. and allied defense against terrorists, cyber threat actors, and others who threaten our individual and collective security. Both parties to these relationships benefit.

One of the most successful sets of international partnerships for signals intelligence is the coalition that NSA developed to support U.S. and allied troops in Iraq and Afghanistan. The combined efforts of as many as 14 nations provided signals intelligence support that saved U.S. and allied lives by helping to identify and neutralize extremist threats across the breadth of both battlefields. The senior U.S. commander in Iraq credited signals intelligence with being a prime reason for the significant progress made by U.S. troops in the 2008 surge, directly enabling the removal of almost 4,000 insurgents from the battlefield.

NSA has an internal oversight and compliance framework to provide assurance that NSA's activities - its people, its technology, and its operations - act consistently with the law and with NSA and U.S. intelligence community policies and procedures. This framework is overseen by multiple organizations external to NSA, including the Director of National Intelligence, the Attorney General, the Congress, and for activities regulated by FISA, the Foreign Intelligence Surveillance Court.

NSA has had different minimization procedures for different types of collection for decades. Among other things, NSA's minimization procedures, to include procedures implemented by United States Signals Intelligence Directive No. SP0018 (USSID 18), provide detailed instructions to NSA personnel on how to handle incidentally acquired U.S. person information. The minimization procedures reflect the reality that U.S. communications flow over the same communications channels that foreign intelligence targets use, and that foreign intelligence targets often discuss information concerning U.S. persons, such as U.S. persons who may be the intended victims of a planned terrorist attack. Minimization procedures direct NSA on the proper way to treat information at all stages of the foreign intelligence process in order to protect U.S. persons' privacy interests.

In 2009 NSA stood up a formal Director of Compliance position, affirmed by Congress in the FY2010 Intelligence Authorization Bill, which monitors verifiable consistency with laws and policies designed to protect U.S. person information during the conduct of NSA's mission. The program managed by the Director of Compliance builds on a number of previous efforts at NSA, and leverages best practices from the professional compliance community in industry and elsewhere in the government. Compliance at NSA is overseen internally by the NSA Inspector General and is also overseen by a number of organizations external to NSA, including the Department of Justice, the Office of the Director of National Intelligence, and the Assistant Secretary of Defense for Intelligence Oversight, the Congress, and the Foreign Intelligence Surveillance Court.

In addition to NSA's compliance safeguards, NSA personnel are obligated to report when they believe NSA is not, or may not be, acting consistently with law, policy, or procedure. This self-reporting is part of the culture and fabric of NSA. If NSA is not acting in accordance with law, policy, or procedure, NSA will report through its internal and external intelligence oversight channels, conduct reviews to understand the root cause, and make appropriate adjustments to constantly improve.
