National Security AgencyFrom Wikipedia, the free encyclopedia
The National Security Agency/Central Security Service (NSA/CSS) is
a cryptologic intelligence agency of the United States Department of
Defense responsible for the collection and analysis of foreign
communications and foreign signals intelligence, as well as protecting
U.S. government communications and information systems,[1] which
involves cryptanalysis and cryptography.
The NSA is directed by at least a lieutenant general or vice admiral. NSA
is a key component of the U.S. Intelligence Community, which is headed
by the Director of National Intelligence. The Central Security Service is a
co-located agency created to coordinate intelligence activities and
co-operation between NSA and other U.S. military cryptanalysis
agencies. The Director of the National Security Agency serves as the
Commander of the United States Cyber Command and Chief of the
Central Security Service.[2]
By law, NSA's intelligence gathering is limited to foreign
communications, although incidents such as the NSA warrantless
surveillance controversy have occurred.

OrganizationThe National Security Agency is divided into two major missions: the Signals Intelligence Directorate (SID), which produces
foreign signals intelligence information, and the Information Assurance Directorate (IAD), which protects U.S. information
systems.[3]
Role
NSA's eavesdropping mission includes radio broadcasting, both from various
organizations and individuals, the Internet, telephone calls, and other intercepted
forms of communication. Its secure communications mission includes military,
diplomatic, and all other sensitive, confidential or secret government
communications. It has been described as the world's largest single employer of
mathematicians,[4] and the owner of the single largest group of supercomputers,[5]
but it has tried to keep a low profile. For many years, its existence was not
acknowledged by the U.S. government, earning it the nickname, "No Such Agency"
(NSA). Because the agency rarely makes any public remarks, it has been quipped
that their motto is "Never Say Anything".[citation needed].
According to the Washington Post, "[e]very day, collection systems at the National
Security Agency intercept and store 1.7 billion e-mails, phone calls and other types
of communications. The NSA sorts a fraction of those into 70 separate databases."[6]
Because of its listening task, NSA/CSS has been heavily involved in cryptanalyticresearch, continuing the work of predecessor agencies which had broken many
World War II codes and ciphers (see, for instance, Purple, Venona project, and
JN-25).
In 2004, NSA Central Security Service and the National Cyber Security Division of the Department of Homeland Security
(DHS) agreed to expand NSA Centers of Academic Excellence in Information Assurance Education Program.[7]
As part of the National Security Presidential Directive 54/Homeland Security Presidential Directive 23 (NSPD 54), signed
on January 8, 2008 by President Bush, the NSA became the lead agency to monitor and protect all of the federal
government's computer networks from cyber-terrorism.[1] In 2010, Robert Gates called for DHS to have a "cell" that would

be able to apply the full surveillance powers of NSA for domestic cyber security.[8]
Facilities
Headquarters for the National Security Agency is at Fort George G.
Meade, Maryland, about 15 mi (24 km) southwest of Baltimore. The
NSA has its own exit off Maryland Route 295 South labeled "NSA
Employees Only." The scale of the operations at the NSA is hard to
determine from unclassified data; some 18,000 parking spaces arevisible in photos of the site. In 2006, theBaltimore Sun reported that the
NSA was at risk of electrical overload because of insufficient internal
electrical infrastructure at Fort Meade to support the amount of
equipment being installed. This problem was apparently recognized in
the 1990s but not made a priority, and "now the agency's ability to keep
its operations going is threatened."[9]
Its secure government
communications work has involved the NSA in numerous technology
areas, including the design of specialized communications hardware and
software, production of dedicated semiconductors (at the Ft. Meade
chip fabrication plant), and advanced cryptography research. The
agency contracts with the private sector in the fields of research and equipment.
In addition to its Ft. Meade headquarters, the NSA has facilities at the Texas Cryptology Center in San Antonio, Texas; at
Fort Gordon, Georgia, and elsewhere.
On January 6, 2011 a groundbreaking ceremony was held to begin construction on the NSA's first Comprehensive National
Cyber-security Initiative (CNCI) Data Center; the "Utah Data Center" for short. The USD $1.5 billion data center is being
built at Camp Williams, Utah, located 25 miles (40 km) miles south of Salt Lake City. The data center will help support the
agency's National Cyber-security Initiative.[10]
National Computer Security Center
The National Computer Security Center, once part of the National Security Agency, was established in 1981 and was
responsible for testing and evaluating computer equipment for use in high security and/or confidential applications. NCSC
was also responsible for publishing the Orange Book and Trusted Network Interpretation (Red Book) detailing trusted
computing and network platform specifications. The two works are more formally known as the Trusted Computing System
Evaluation Criteria and Trusted Network Interpretation, part of the Rainbow Series, however, they have largely been
replaced by the Common Criteria.
History
The National Security Agency's predecessor was the Armed Forces Security Agency (AFSA), created on May 20,
1949.[11]
This organization was originally established within the U.S. Department of Defense under the command of the
Joint Chiefs of Staff. The AFSA was to direct the communications and electronic intelligence activities of the U.S. military
intelligence units: the Army Security Agency, the Naval Security Group, and the Air Force Security Service. However, thatagency had little power and lacked a centralized coordination mechanism. The creation of NSA resulted from a December
10, 1951, memo sent by CIA Director Walter Bedell Smith to James S. Lay, Executive Secretary of the National Security
Council.[12]
The memo observed that "control over, and coordination of, the collection and processing of Communications
Intelligence had proved ineffective" and recommended a survey of communications intelligence activities. The proposal was
approved on December 13, 1951, and the study authorized on December 28, 1951. The report was completed by June 13,
1952. Generally known as the "Brownell Committee Report," after committee chairman Herbert Brownell, it surveyed the
history of U.S. communications intelligence activities and suggested the need for a much greater degree of coordination and
direction at the national level. As the change in the security agency's name indicated, the role of NSA was extended beyond
the armed forces.

National Cryptologic Memorial
The NSA's insignia.
The creation of NSA was authorized in a letter written by President Harry S. Truman in June 1952. The agency was formally
established through a revision of National Security Council Intelligence Directive (NSCID) 9 on October 24, 1952,[12] and
officially came into existence on November 4, 1952. President Truman's letter was itself classified and remained unknown
to the public for more than a generation. A brief but vague reference to the NSA first appeared in the United States
Government Organization Manual from 1957, which described it as "a separately organized agency within the Department
of Defense under the direction, authority, and control of the Secretary of Defense [...] for the performance of highly
specialized technical functions in support of the intelligence activities of the United States."[13]
National Cryptologic Memorial
Crews associated with NSA missions have been involved in a number of
dangerous and deadly situations. The well known USS Liberty incident in 1967
and USS Pueblo incident in 1968 are a small sample of the losses endured
during the Cold War.[14]
The National Security Agency/Central Security Service Cryptologic Memorial
honors and remembers the fallen personnel, both military and civilian, of these
intelligence missions. It is made of black granite, and has 163 names (as of
2011) carved into it. It is located at NSA headquarters. A tradition of
declassifying the stories of the fallen was begun in 2001.[15]
Insignia
The heraldic insignia of NSA consists of a bald eagle facing its right, grasping a key in its talons,
representing NSA's clutch on security as well as the mission to protect and gain access to secrets.
The eagle is set on a background of blue and its breast features a blue shield supported by 13 bands
of red and white. The surrounding white circular border features "National Security Agency"
around the top and "United States of America" underneath, with two five-pointed silver stars
between the two phrases. The current NSA insignia has been in use since 1965, when then-Director,
LTG Marshall S. Carter (USA) ordered the creation of a device to represent the Agency.[16]
Effect on non-governmental cryptography
NSA has been involved in debates about public policy, both indirectly as a behind-the-scenes adviser to other departments,
and directly during and after Vice Admiral Bobby Ray Inman's directorship. NSA was a major player in the debates of the
1990s regarding the export of cryptography. Restrictions on export were reduced but not eliminated in 1996.
Data Encryption Standard (DES)
Main article: Data Encryption Standard
NSA was embroiled in some minor controversy concerning its involvement in the creation of the Data Encryption Standard
(DES), a standard and public block cipher algorithm used by the U.S. government and banking community. During the
development of DES by IBM in the 1970s, NSA recommended changes to some details of the design. There was suspicionthat these changes had weakened the algorithm sufficiently to enable the agency to eavesdrop if required, including
speculation that a critical componentthe so-called S-boxeshad been altered to insert a "backdoor" and that the
reduction in key length might have made it feasible for NSA to discover DES keys using massive computing power. It has
since been observed that the S-boxes in DES are particularly resilient against differential cryptanalysis, a technique which
was not publicly discovered until the late 1980s, but which was known to the IBM DES team. The United States Senate
Select Committee on Intelligence reviewed NSA's involvement, and concluded that while the agency had provided some
assistance, it had not tampered with the design.[17][18] In late 2009 NSA declassified information stating that "NSA worked
closely with IBM to strengthen the algorithm against all except brute force attacks and to strengthen substitution tables,
called S-boxes. Conversely, NSA tried to convince IBM to reduce the length of the key from 64 to 48 bits. Ultimately they
compromised on a 56-bit key."[19]

Clipper chip
Main article: Clipper chip
Because of concerns that widespread use of strong cryptography would hamper government use of wiretaps, NSA proposed
the concept of key escrow in 1993 and introduced the Clipper chip that would offer stronger protection than DES but would
allow access to encrypted data by authorized law enforcement officials. The proposal was strongly opposed and key escrow
requirements ultimately went nowhere. However, NSA's Fortezza hardware-based encryption cards, created for the Clipper
project, are still used within government, and NSA ultimately published the design of the SKIPJACK cipher (but not the key
exchange protocol) used on the cards.
Advanced Encryption Standard (AES)
Main article: Advanced Encryption Standard
Possibly because of previous controversy, the involvement of NSA in the selection of a successor to DES, the Advanced
Encryption Standard (AES), was initially limited to hardware performance testing (see AES competition). NSA has
subsequently certified AES for protection of classified information (for at most two levels, e.g. SECRET information in an
unclassified environment) when used in NSA-approved systems.
SHA
The widely-used SHA-1 and SHA-2 hash functions were designed by NSA. SHA-1 is a slight modification of the weaker
SHA-0 algorithm, also designed by NSA in 1993. This small modification was suggested by NSA two years later, with no
ustification other than the fact that it provides additional security. An attack for SHA-0 that does not apply to the revised
algorithm was indeed found between 1998 and 2005 by academic cryptographers. Because of weaknesses and key length
restrictions in SHA-1, NIST deprecates its use for digital signatures, and approves only the newer SHA-2 algorithms for such
applications from 2013 on.[20]
A new hash standard, SHA-3, is currently under development. An ongoing competition, closely resembling the successful
AES process, will select the function used by the standard and is scheduled to end in 2012.
Dual EC DRBG random number generator
Main article: Dual EC DRBG
NSA promoted the inclusion of a random number generator called Dual EC DRBG in the U.S. National Institute of
Standards and Technology's 2007 guidelines. This led to speculation of a backdoor which would allow NSA access to data
encrypted by systems using that random number generator.[21]
Academic research
NSA has invested many millions of dollars in academic research under grant code prefix MDA904, resulting in over 3,000
papers (as of 2007-10-11). NSA/CSS has, at times, attempted to restrict the publication of academic research into
cryptography; for example, the Khufu and Khafre block ciphers were voluntarily withheld in response to an NSA request to
do so.

Behind the Green Doorsecure communications
center with SIPRNET, GWAN, NSANET, and
JWICS access
NSANet is the official National Security Agency intranet.[22]
It is a
classified internal network,[23] and TS/SCI.[24] In 2004 it was reported to
have used over 20 commercial off-the-shelf operating systems.[25]
Some
universities that do highly-sensitive research are allowed to connect to
it.[26] In 1998 it, along with NIPRNET and SIPRNET, had "significant
problems with poor search capabilities, unorganized data and old
information".[27] In 2001 it was reported on the PR Newswire that NSA
bought Auto-Trol's product KONFIG NM to help "document and
manage" NSANet.[22][23][24][25][26][27][28][29]
Patents
NSA has the ability to file for a patent from the U.S. Patent and Trademark
Office under gag order. Unlike normal patents, these are not revealed to the
public and do not expire. However, if the Patent Office receives an application for an identical patent from a third party,
they will reveal NSA's patent and officially grant it to NSA for the full term on that date.[30]
One of NSA's published patents describes a method of geographically locating an individual computer site in an Internet-like
network, based on the latency of multiple network connections.[31]
NSA programs
ECHELON
Main article: ECHELON
NSA/CSS, in combination with the equivalent agencies in the United Kingdom (Government Communications
Headquarters) , Canada (Communications Security Establishment), Australia (Defence Signals Directorate), and New
Zealand (Government Communications Security Bureau), otherwise known as the UKUSA group,[32] is widely reported to
be in command of the operation of the so-called ECHELON system. Its capabilities are suspected to include the ability to
monitor a large proportion of the world's transmitted civilian telephone, fax and data traffic, according to a December 16,
2005 article in theNew York Times.[33]
Technically, almost all modern telephone, internet, fax and satellite communications are exploitable due to recent advances
in technology and the 'open air' nature of much of the radio communications around the world. NSA's presumed collection
operations have generated much criticism, possibly stemming from the assumption that NSA/CSS represents an infringement
of Americans' privacy. However, NSA's United States Signals Intelligence Directive 18 (USSID 18) strictly prohibits the
interception or collection of information about "...U.S. persons, entities, corporations or organizations..." without explicit
written legal permission from the United States Attorney General when the subject is located abroad, or the Foreign
Intelligence Surveillance Court when within U.S. Borders.[34] The U.S. Supreme Court has ruled that intelligence agencies
cannot conduct surveillance against American citizens. There are a few extreme circumstances where collecting on a U.S.
entity is allowed without a USSID 18 waiver, such as with civilian distress signals, or sudden emergencies such as theSeptember 11, 2001 attacks; however, the USA PATRIOT Act has significantly changed privacy legality.
There have been alleged violations of USSID 18 that occurred in violation of NSA's strict charter prohibiting such
acts.[citation needed] In addition, ECHELON is considered with indignation by citizens of countries outside the UKUSA
alliance, with numerous allegations that the United States government uses it for motives other than its national security,
including political and industrial espionage.[35][36] Examples include the gear-less wind turbine technology designed by the
German firm Enercon[37][38]
and the speech technology developed by the Belgian firm Lernout & Hauspie. An article in the
Baltimore Sun reported in 1995 that aerospace company Airbus lost a $6 billion contract with Saudi Arabia in 1994 after
NSA reported that Airbus officials had been bribing Saudi officials to secure the contract.[39][40]

Domestic activity
NSA's mission, as set forth in Executive Order 12333, is to collect information that constitutes "foreign intelligence or
counterintelligence" while not"acquiring information concerning the domestic activities of United States persons". NSA has
declared that it relies on the FBI to collect information on foreign intelligence activities within the borders of the USA, while
confining its own activities within the USA to the embassies and missions of foreign nations.
NSA's domestic surveillance activities are limited by the requirements imposed by the Fourth Amendment to the U.S.
Constitution; however, these protections do not apply to non-U.S. persons located outside of U.S. borders, so the NSA's
foreign surveillance efforts are subject to far fewer limitations under U.S. law.[41] The specific requirements for domestic
surveillance operations are contained in the Foreign Intelligence Surveillance Act of 1978 (FISA), which does not extend
protection to non-U.S. citizens located outside of U.S. territory.[41]
These activities, especially the publicly acknowledged domestic telephone tapping and call database programs, have
prompted questions about the extent of the NSA's activities and concerns about threats to privacy and the rule of law.
Wiretapping programs
Domestic wiretapping under Richard Nixon
Further information: Church Committee
In the years after President Richard Nixon resigned, there were several investigations of suspected misuse of Central
Intelligence Agency (CIA) and NSA facilities. Senator Frank Church headed a Senate investigating committee (the Church
Committee) which uncovered previously unknown activity, such as a CIA plot (ordered by President John F. Kennedy) to
assassinate Fidel Castro. The investigation also uncovered NSA's wiretaps on targeted American citizens. After the Church
Committee hearings, the Foreign Intelligence Surveillance Act of 1978 became law, limiting circumstances under which
domestic surveillance was allowed.
IT projects: ThinThread, Trailblazer, Turbulence
NSA created new IT systems to deal with the flood of information from new technologies like the internet and cellphones.
ThinThread contained advanced data mining capabilities. It also had a 'privacy mechanism'; surveillance was stored
encrypted; decryption required a warrant. The research done under this program may have contributed to the technology
used in later systems. Thinthread was cancelled when Michael Hayden chose Trailblazer, which did not include Thinthread's
privacy system.[42]
Trailblazer ramped up circa 2000. SAIC, Boeing, CSC, IBM, and Litton worked on it. Some NSA whistleblowers
complained internally about major problems surrounding Trailblazer. This led to investigations by Congress and the NSA and
DoD Inspectors General. The project was cancelled circa 2003-4; it was late, overbudget, and didn't do what it was
supposed to do. The Baltimore Sun ran articles about this in 2006-07. The government then raided the whistleblower's
houses. One of them, Thomas Drake, was charged with 18 U.S.C. 793(e) (http://www.law.cornell.edu/uscode
/18/793.html#e) in 2010, part of Obama's unusual use of espionage law against leakers and whistleblowers.[43][44]
Turbulence started circa 2005. It was developed in small, inexpensive 'test' pieces rather than one grand plan like
Trailblazer. It also included offensive cyber-warfare capabilities, like injecting malware into remote computers. Congress
criticized Turbulence in 2007 for having similar bureaucratic problems as Trailblazer.[44]
Warrantless wiretaps under George W. Bush
Main article: NSA warrantless surveillance controversy
On December 16, 2005, theNew York Times reported that, under White House pressure and with an executive order from
President George W. Bush, the National Security Agency, in an attempt to thwart terrorism, had been tapping the
nal Security Agency - Wikipedia, the free encyclopedia http://en.wikipedia.org/wiki/National_Securit

telephones of select individuals in the U.S. calling persons outside the country, without obtaining warrants from the United
States Foreign Intelligence Surveillance Court, a secret court created for that purpose under the Foreign Intelligence
Surveillance Act (FISA).[45]
One such surveillance program, authorized by the U.S. Signals Intelligence Directive 18 of President George Bush, was the
Highlander Project undertaken for the National Security Agency by the U. S. Army 513th Military Intelligence Brigade.
NSA relayed telephone (including cell phone) conversations obtained from both ground, airborne, and satellite monitoring
stations to various U.S. Army Signal Intelligence Officers, including the 201st Military Intelligence Battalion. Conversations
of citizens of the U.S. were intercepted, along with those of other nations.
[46]
Proponents of the surveillance program claim that the President has executive authority to order such action, arguing that
laws such as FISA are overridden by the President's Constitutional powers. In addition, some argued that FISA was
implicitly overridden by a subsequent statute, the Authorization for Use of Military Force, although the Supreme Court's
ruling in Hamdan v. Rumsfeld deprecates this view. In the August 2006 caseACLU v. NSA, U.S. District Court Judge Anna
Diggs Taylor concluded that NSA's warrantless surveillance program was both illegal and unconstitutional. On July 6, 2007
the 6th Circuit Court of Appeals overturned Judge Taylor's ruling, reversing her findings.[47]
AT&T Internet monitoring
Further information: Hepting v. AT&T, Mark Klein, NSA warrantless surveillance controversy
In May 2006, Mark Klein, a former AT&T employee, alleged that his company had cooperated with NSA in installing
hardware to monitor network communications including traffic between American citizens.[48]
Wiretapping under Barack Obama
The New York Times reported in 2009 that the NSA is intercepting communications of American citizens including a
Congressman, although the Justice Department believed that the NSA had corrected its errors.[49] United States Attorney
General Eric Holder resumed the wiretapping according to his understanding of the Foreign Intelligence Surveillance Act of
1978 Amendments Act of 2008 which Congress passed in July 2008 but without explaining what had occurred.[50]
Transaction data mining
NSA is reported to use its computing capability to analyze "transactional" data that it regularly acquires from other
government agencies, which gather it under their own jurisdictional authorities. As part of this effort, NSA now monitors
huge volumes of records of domestic emails and Internet searches as well as bank transfers, credit-card transactions and
travel and telephone records, according to current and former intelligence officials interviewed by the Wall Street
Journal.[51]
Criticisms
The NSA received criticism early on in 1960 after two agents had defected to the Soviet Union. Investigations by the House
Un-American Activities Committee and a special subcommittee of the House Armed Services Committee revealed severecases of ignorance in personnel security regulations, prompting the former personnel director and the director of security to
step down and leading to the adoption of stricter security practices.[13] Nonetheless, security breaches reoccurred only a
year later when in an issue of Izvestia of July 23, 1963, a former NSA employee published several cryptologic secrets. The
very same day, an NSA clerk-messenger committed suicide as ongoing investigations disclosed that he had sold secret
information to the Soviets on a regular basis. The reluctance of Congressional houses to look into these affairs had prompted
a journalist to write "If a similar series of tragic blunders occurred in any ordinary agency of Government an aroused public
would insist that those responsible be officially censured, demoted, or fired." David Kahn criticized the NSA's tactics of
concealing its doings as smug and the Congress' blind faith in the agency's right-doing as shortsighted, and pointed out the
necessity of surveillance by the Congress to prevent abuse of power.[13]

The number of exemptions from legal requirements has also been criticized. When in 1964 the Congress was hearing a bill
giving the director of the NSA the power to fire at will any employee, the Washington Post wrote: "This is the very
definition of arbitrariness. It means that an employee could be discharged and disgraced on the basis of anonymous
allegations without the slightest opportunity to defend himself." Yet, the bill was accepted with overwhelming majority.[13]
On January 17, 2006, the Center for Constitutional Rights filed a lawsuit, CCR v. Bush, against the Bush Presidency. The
lawsuit challenged the National Security Agency's (NSA's) surveillance of people within the U.S., including the interception
of CCR emails without securing a warrant first.[52][53]
In fiction
Main article: NSA in fiction
Since the existence of the NSA has become more widely known in the past few decades, and particularly since the 1990s,
the agency has regularly been portrayed in spy fiction. Many such portrayals grossly exaggerate the organization's
involvement in the more sensational activities of intelligence agencies. The agency now plays a role in numerous books,
films, television shows, and video games.
