Classified information is material that a government body claims is sensitive information that requires protection of confidentiality, integrity, or availability.
 Access is restricted by law or regulation to particular groups of people, and mishandling can incur criminal penalties and loss of respect.
 A formal security clearance is often required to handle classified documents or access classified data.
 The clearance process usually requires a satisfactory background investigation.
 Documents and other information assets are typically marked with one of several (hierarchical) levels of sensitivity—e.g. restricted, confidential, secret and top secret.
 The choice of level is often based on an impact assessment; governments often have their own set of rules which include the levels, rules on determining the level for an information asset, and rules on how to protect information classified at each level.
 This often includes security clearances for personnel handling the information.
 Although "classified information" refers to the formal categorization and marking of material by level of sensitivity, it has also developed a sense synonymous with "censored" in US English.
 A distinction is often made between formal security classification and privacy markings such as "commercial in confidence".
 Classifications can be used with additional keywords that give more detailed instructions on how data should be used or protected.
Standard Form 312 (SF 312) is a non-disclosure agreement required under Executive Order 13292 to be signed by employees of the U.S. Federal Government or one of its contractors when they are granted a security clearance for access to classified information.
 The form is issued by the Information Security Oversight Office of the National Archives and Records Administration and its title is "Classified Information Nondisclosure Agreement."
 SF 312 prohibits confirming or repeating classified information to unauthorized individuals, even if that information is already leaked.
 The SF 312 replaces the earlier forms SF 189 or the SF 189-A.
 Enforcement of SF-312 is limited to civil actions to enjoin disclosure or seek monetary damages and administrative sanctions, "including reprimand, suspension, demotion or removal, in addition to the likely loss of the security clearance."

The State Security Department or VSD (Lithuanian: "Valstybės saugumo departamentas" ) is a Lithuanian national security agency which collects information on threats to Lithuania's sovereignty and works to eliminate those threats.
 The VSD also conducts counterintelligence, protects state secrets and classified information, and vets applicants for residence in or entry to Lithuania.
 The department was established on 26 March 1990, two weeks after Lithuania declared independence from the Soviet Union.
 At the time, the department was also responsible for certain aspects of law enforcement, provide protection to state officials and strategic objects, ensure integrity of state communications network, investigate political corruption.
 Other agencies took over these extra duties and, during 2010, the mission of VSD was clarified to mainly focus on intelligence and counterintelligence.
The statue of Edward Snowden, called Prison Ship Martyrs' Monument 2.0 by its creators, was an ephemeral, illegally installed public statue of Edward Snowden, an American whistleblower who leaked classified information from the National Security Agency (NSA) and was charged with federal crimes as a result.
 The bronze-like statue was placed in Fort Greene Park in Fort Greene, Brooklyn, New York City, on April 6, 2015.

Fishbowl is a mobile phone architecture developed by the U.S. National Security Agency (NSA) to provide a secure Voice over IP (VoIP) capability using commercial grade products that can be approved to communicate classified information.
 It is the first phase of NSA's Enterprise Mobility Architecture.
 According to a presentation at the 2012 RSA Conference by Margaret Salter, a Technical Director in the Information Assurance Directorate, “The plan was to buy commercial components, layer them together and get a secure solution.
 It uses solely commercial infrastructure to protect classified data."
 Government employees were reportedly testing 100 of the phones as of the announcement.
United States Army Security Agency (USASA) Field Station Augsburg was the site of a Wullenweber AN/FLR-9 radio direction finder, established during the Cold War.
 Field Station Augsburg was located on Gablingen Kaserne, near the village of Gablingen just north of Augsburg in Bavaria, West Germany.
 It was one of nearly 20 Field Stations positioned strategically around the world by U.S. Armed Forces during the Cold War.
 Field Station Augsburg opened in 1971 and closed in 1998, at which time it was turned over to the German government.
 It was owned and managed by the National Security Agency and manned by the U.S. Army Security Agency (USASA), which later became U.S. Army INSCOM (Intelligence and Security Command), in conjunction with other branches of the U.S. Military and various allied forces.
 Personnel assigned to Field Station Augsburg were composed of individuals who scored high enough on the Army entrance exams to be classified as "ST" or a skilled technician, which is the Army's top-ranked job category.
 Field Station Augsburg was manned 24 hours a day, by means of rotating shifts, as part of the effort to ensure the safety and security of the U.S., as are any country's intelligence operations.
 There was a saying in the '70s that if the intelligence units were able to effectively do their job, the combat units wouldn't have to do theirs.
 The mission of USAFSA was to monitor the communications of Cold War enemy nations, their allies, and client states around the world.
 The information gathered was time-sensitive and, based on its importance and classification, that information was collected, analyzed and passed through intelligence channels on a "real-time" basis.
Optic Nerve is a mass surveillance program run by the British signals intelligence agency Government Communications Headquarters (GCHQ), with help from the US National Security Agency, that surreptitiously collects private webcam still images from users while they are using a Yahoo! webcam application.
 As an example of the scale, in one 6-month period, the program is reported to have collected images from 1.8 million Yahoo! user accounts globally.
 The program was first reported on in the media in February 2014, from documents leaked by the former National Security Agency contractor Edward Snowden, but dates back to a prototype started in 2008, and was still active in at least 2012.
