National security of the United States is a collective term encompassing the policies of both U.S. national defense and foreign relations. [1]
Measures taken to ensure U.S. national security include:
The phrase “national security” entered U.S. political discourse as early as the Constitutional Convention. The Federalists argued that civilian control of the military required a strong central government under a single constitution. Alexander Hamilton wrote: “If a well-regulated militia be the most natural defense of a free country, it ought certainly to be under the regulation and at the disposal of that body which is constituted the guardian of the national security.” [3]
U.S. National Security organization has remained essentially stable since July 26, 1947, when U.S. President Harry S. Truman signed the National Security Act of 1947. Together with its 1949 amendment, this act:
After 9/11, the passage of the USA Patriot Act provoked debate about the alleged restriction of individual rights and freedoms for the sake of U.S. national security. The easing of warrant requirements for intelligence surveillance, under Title II of the Act, spurred the NSA warrantless surveillance controversy. [5] In August 2008, the United States Foreign Intelligence Surveillance Court of Review (FISCR) affirmed the constitutionality of warrantless national security surveillance. [6]
The USA PATRIOT Act was a landmark Act of the United States Congress, signed into law by President George W. Bush. The formal name of the statute is the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001, and the commonly used short name is a contrived acronym that is embedded in the name set forth in the statute.
The Posse Comitatus Act is a United States federal law signed on June 18, 1878, by President Rutherford B. Hayes that limits the powers of the federal government in the use of federal military personnel to enforce domestic policies within the United States. Congress passed the Act as an amendment to an army appropriation bill following the end of Reconstruction and updated it in 1956, 1981 and 2021.
Counterterrorism, also known as anti-terrorism, relates to the practices, military tactics, techniques, and strategies that governments, law enforcement, businesses, and intelligence agencies use to combat or eliminate terrorism and violent extremism.
Wiretapping, also known as wire tapping or telephone tapping, is the monitoring of telephone and Internet-based conversations by a third party, often by covert means. The wire tap received its name because, historically, the monitoring connection was an actual electrical tap on an analog telephone or telegraph line. Legal wiretapping by a government agency is also called lawful interception. Passive wiretapping monitors or records the traffic, while active wiretapping alters or otherwise affects it.

The Foreign Intelligence Surveillance Act of 1978 is a United States federal law that establishes procedures for the surveillance and collection of foreign intelligence on domestic soil.
The United States Foreign Intelligence Surveillance Court of Review (FISCR) is a U.S. federal court whose sole purpose is to review denials of applications for electronic surveillance warrants by the United States Foreign Intelligence Surveillance Court. The FISCR was established by the Foreign Intelligence Surveillance Act of 1978 and consists of a panel of three judges. Like the FISC, the FISCR is not an adversarial court; rather, the only party to the court is the federal government, although other parties may submit briefs as amici curiae if they are made aware of the proceedings. Papers are filed and proceedings are held in secret. Records of the proceedings are kept classified, though copies of the proceedings with sensitive information redacted are very occasionally made public. The government may appeal decisions of the FISCR to the Supreme Court of the United States, which hears appeals on a discretionary basis.
NSA warrantless surveillance — also commonly referred to as "warrantless-wiretapping" or "-wiretaps" — was the surveillance of persons within the United States, including U.S. citizens, during the collection of notionally foreign intelligence by the National Security Agency (NSA) as part of the Terrorist Surveillance Program. In late 2001, the NSA was authorized to monitor, without obtaining a FISA warrant, phone calls, Internet activities, text messages and other forms of communication involving any party believed by the NSA to be outside the U.S., even if the other end of the communication lies within the U.S.
United States v. U.S. District Court, 407 U.S. 297 (1972), also known as the Keith Case, was a landmark United States Supreme Court decision that upheld, in a unanimous 8-0 ruling, the requirements of the Fourth Amendment in cases of domestic surveillance targeting a domestic threat.
Hepting v. AT&T, 439 F.Supp.2d 974, was a class action lawsuit argued before the United States District Court for the Northern District of California, filed by Electronic Frontier Foundation (EFF) on behalf of customers of the telecommunications company AT&T. The plaintiffs alleged that AT&T permitted and assisted the National Security Agency (NSA) in unlawfully monitoring the personal communications of American citizens, including AT&T customers, whose communications were routed through AT&T's network.

The Authorization for Use of Military Force is a joint resolution of the United States Congress which became law on September 18, 2001, authorizing the use of the United States Armed Forces against those responsible for the September 11 attacks. The authorization granted the president the authority to use all "necessary and appropriate force" against those whom he determined "planned, authorized, committed or aided" the September 11 attacks, or who harbored said persons or groups. The AUMF was passed by the 107th Congress on September 18, 2001, and signed into law by President George W. Bush on September 18, 2001. Since its passage in 2001, U.S. presidents have interpreted their authority under the AUMF to extend beyond al Qaeda and the Taliban in Afghanistan to apply to numerous other groups as well as other geographic locales, due to the act's omission of any specific area of operations. In December 2016, the Office of the President published a brief interpreting the AUMF as providing congressional authorization for the use of force against al-Qaeda and other militant groups. Today, the full list of actors the U.S. military is fighting or believes itself authorized to fight under the 2001 AUMF is classified.
The Protect America Act of 2007 (PAA),, is a controversial amendment to the Foreign Intelligence Surveillance Act (FISA) that was signed into law by U.S. President George W. Bush on August 5, 2007. It removed the warrant requirement for government surveillance of foreign intelligence targets "reasonably believed" to be outside the United States. The FISA Amendments Act of 2008 reauthorized many provisions of the Protect America Act in Title VII of FISA.
The FISA Amendments Act of 2008, also called the FAA and Foreign Intelligence Surveillance Act of 1978 Amendments Act of 2008, is an Act of Congress that amended the Foreign Intelligence Surveillance Act. It has been used as the legal basis for surveillance programs disclosed by Edward Snowden in 2013, including PRISM.
"Stellar Wind" was the code name of a warrantless surveillance program begun under the George W. Bush administration's President's Surveillance Program (PSP). The National Security Agency (NSA) program was approved by President Bush shortly after the September 11, 2001 attacks and was revealed by Thomas Tamm to The New York Times in 2004. Stellar Wind was a prelude to new legal structures that allowed President Bush and President Barack Obama to reproduce each of those programs and expand their reach.
EPIC v. Department of Justice is a 2014 case in the United States District Court for the District of Columbia between the Electronic Privacy Information Center (EPIC) and the U.S. Department of Justice (DOJ) where EPIC seeks court action to enforce their Freedom of Information Act request for documents that the Department of Justice has withheld pertaining to George W. Bush's authorization of NSA warrantless surveillance.
The President's Surveillance Program (PSP) is a collection of secret intelligence activities authorized by the President of the United States George W. Bush after the September 11 attacks in 2001 as part of the War on Terrorism. Information collected under this program was protected within a Sensitive Compartmented Information security compartment codenamed STELLARWIND.
Clapper v. Amnesty International USA, 568 U.S. 398 (2013), was a United States Supreme Court case in which the Court held that Amnesty International USA and others lacked standing to challenge section 702 of the Foreign Intelligence Surveillance Act of 1978, as amended by the Foreign Intelligence Surveillance Act of 1978 Amendments Act of 2008.
The FISA Improvements Act is a proposed act by Senator Dianne Feinstein, Chair of the Senate Intelligence Committee. Prompted by the disclosure of NSA surveillance by Edward Snowden, it would establish the surveillance program as legal, but impose some limitations on availability of the data. Opponents say the bill would codify warrantless access to many communications of American citizens for use by domestic law enforcement.
