In the security engineering subspecialty of computer science, a trusted system is one that is relied upon to a specified extent to enforce a specified security policy. This is equivalent to saying that a trusted system is one whose failure would break a security policy.
Classified information is material that a government body deems to be sensitive information that must be protected. Access is restricted by law or regulation to particular groups of people with the necessary security clearance and need to know. Mishandling of the material can incur criminal penalties.
A security clearance is a status granted to individuals allowing them access to classified information or to restricted areas, after completion of a thorough background check. The term "security clearance" is also sometimes used in private organizations that have a formal process to vet employees for access to sensitive information. A clearance by itself is normally not sufficient to gain access; the organization must also determine that the cleared individual needs to know specific information. No individual is supposed to be granted automatic access to classified information solely because of rank, position, or a security clearance.
Sensitive compartmented information (SCI) is a type of United States classified information concerning or derived from sensitive intelligence sources, methods, or analytical processes. All SCI must be handled within formal access control systems established by the Director of National Intelligence.
A sensitive compartmented information facility, in United States military, national security/national defense and intelligence parlance, is an enclosed area within a building that is used to process sensitive compartmented information (SCI) types of classified information.
Redaction or sanitization is the process of removing sensitive information from a document so that it may be distributed to a broader audience. It is intended to allow the selective disclosure of information. Typically, the result is a document that is suitable for publication or for dissemination to others rather than the intended audience of the original document.
The United States government classification system is established under Executive Order 13526, the latest in a long series of executive orders on the topic of classified information beginning in 1951. Issued by President Barack Obama in 2009, Executive Order 13526 replaced earlier executive orders on the topic and modified the regulations codified to 32 C.F.R. 2001. It lays out the system of classification, declassification, and handling of national security information generated by the U.S. government and its employees and contractors, as well as information received from other governments.
Special access programs (SAPs) in the U.S. Federal Government are security protocols that provide highly classified information with safeguards and access restrictions that exceed those for regular (collateral) classified information. SAPs can range from black projects to routine but especially-sensitive operations, such as COMSEC maintenance or presidential transportation support. In addition to collateral controls, a SAP may impose more stringent investigative or adjudicative requirements, specialized nondisclosure agreements, special terminology or markings, exclusion from standard contract investigations (carve-outs), and centralized billet systems. Within the Department of Defense, SAP is better known as "SAR" by the mandatory Special Access Required (SAR) markings.
Multiple single-level or multi-security level (MSL) is a means to separate different levels of data by using separate computers or virtual machines for each level. It aims to give some of the benefits of multilevel security without needing special changes to the OS or applications, but at the cost of needing extra hardware.
Classified information in the United Kingdom is a system used to protect information from intentional or inadvertent release to unauthorised readers. The system is organised by the Cabinet Office and is implemented throughout central and local government and critical national infrastructure. The system is also used by private sector bodies that provide services to the public sector.
Compartmentalization, in information security, whether public or private, is the limiting of access to information to persons or other entities on a need-to-know basis to perform certain tasks.
This page is a timeline of published security lapses in the United States government. These lapses are frequently referenced in congressional and non-governmental oversight. This article does not attempt to capture security vulnerabilities.
National intelligence programs, and, by extension, the overall defenses of nations, are vulnerable to attack. It is the role of intelligence cycle security to protect the process embodied in the intelligence cycle, and that which it defends. A number of disciplines go into protecting the intelligence cycle. One of the challenges is there are a wide range of potential threats, so threat assessment, if complete, is a complex task. Governments try to protect three things:
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.
A variety of networks operating in special security domains handle classified information in the United States or sensitive but unclassified information, while other specialized networks are reserved specifically for unclassified use by the same agencies. Some sites accessed from these networks have been referred to as "classified websites" in official communications, such as the American embassy "Amman's Classified Web Site at http://www.state.sgov.gov/pinea/amman/" and "Mexico City's Classified Web Site at http://www.state.sgov.gov/p/wha/mexicocity" Some of these trace back to the Defense Data Network which split from the Internet in 1983.
PRISM is a code name for a program under which the United States National Security Agency (NSA) collects internet communications from various U.S. internet companies. The program is also known by the SIGAD US-984XN. PRISM collects stored internet communications based on demands made to internet companies such as Google LLC and Apple under Section 702 of the FISA Amendments Act of 2008 to turn over any data that match court-approved search terms. Among other things, the NSA can use these PRISM requests to target communications that were encrypted when they traveled across the internet backbone, to focus on stored data that telecommunication filtering systems discarded earlier, and to get data that is easier to handle.
Bullrun is a clandestine, highly classified program to crack encryption of online communications and data, which is run by the United States National Security Agency (NSA). The British Government Communications Headquarters (GCHQ) has a similar program codenamed Edgehill. According to the Bullrun classification guide published by The Guardian, the program uses multiple methods including computer network exploitation, interdiction, industry relationships, collaboration with other intelligence community entities, and advanced mathematical techniques.
The Government Security Classifications Policy (GSCP) is a system for classifying sensitive government data in the United Kingdom.
Donald Trump's handling of United States government records, especially those containing classified information, during his tenure as the 45th U.S. president has come under scrutiny. A number of incidents in which the president disclosed classified information to foreign powers and private individuals have become publicly known, sometimes with distinct national security and diplomatic consequences.

The process of being "read into" a compartmented program generally entails being approved for access to particularly sensitive and restricted information about a classified program, receiving a briefing about the program, and formally acknowledging the briefing, usually by signing a nondisclosure agreement describing restrictions on the handling and use of information concerning the program

It is true by definition that the classification markings were new to Goldsmith, because the program was codeword-classified. Until an official is "read in," he does not know there is a special access program with that codeword.
