through physical searches may be used. Section 504 of the Patriot Act modified FISA to allow Federal officers who acquire information through electronic surveillance or physical searches to consult with Federal law enforcement officers to coordinate efforts to investigate or protect against potential or actual attacks, sabotage or international terrorism or clandestine intelligence activities by an intelligence service or network of a foreign power. National security authorities Three national security authorities were modified under title V of the Patriot Act. FISA granted counterintelligence access to telephone toll and transactional records through the use of National Security Letters (NSLs). It required electronic communication service providers to comply with a request for subscriber information and toll billing records information, or electronic communication transactional records when so asked by the FBI. The disclosure by any recipient of an NSL was prohibited as under § 2709(c) they were not able to tell anyone that the FBI had sought or obtained access to records of the person who was being targeted by the NSL. The Right to Financial Privacy Act of 1978 gives the FBI authority to require financial institutions to provide information about their customer’s or an entity’s financial records. The Fair Credit Reporting Act requires a consumer reporting agency to provide the FBI the names and addresses of all financial institutions at which a consumer maintains or has maintained an account. Section 505 of the Patriot Act allowed the use of NSLs to be made by a Special Agent in charge of a Bureau field office. Previously only the Director or the Deputy Assistant Director of the FBI were able to certify such requests. The requests for counterintelligence access to telephone toll and transactional records made under FISA can ask for the name, address, length of service, and local and long distance toll billing records of a subscriber, or the name, address, and length of service of an employee of the provider. The Patriot Act modified all the authorities mentioned above to allow for requests for information to be granted only if written certification is provided that the information is "relevant to an authorized investigation to protect against international terrorism or clandestine intelligence activities, provided that such an investigation of a United States person is not conducted solely on the basis of activities protected by the first amendment to the Constitution of the United States".
