Operations security (OPSEC) is a process that identifies critical information to determine whether friendly actions can be observed by enemy intelligence, determines if information obtained by adversaries could be interpreted to be useful to them, and then executes selected measures that eliminate or reduce adversary exploitation of friendly critical information.
The term "operations security" was coined by the United States military during the Vietnam War.
In 1966, United States Admiral Ulysses Sharp established a multidisciplinary security team to investigate the failure of certain combat operations during the Vietnam War. This operation was dubbed Operation Purple Dragon, and included personnel from the National Security Agency and the Department of Defense. [1]
When the operation concluded, the Purple Dragon team codified their recommendations. They called the process "Operations Security" in order to distinguish the process from existing processes and ensure continued inter-agency support. [2]
In 1988, President Ronald Reagan signed National Security Decision Directive (NSDD) 298. This document established the National Operations Security Program and named the Director of the National Security Agency as the executive agent for inter-agency OPSEC support. This document also established the Interagency OPSEC Support Staff (IOSS). [3]
The private sector has also adopted OPSEC as a defensive measure against competitive intelligence collection efforts. [4]
NIST SP 800-53 defines OPSEC as the "process by which potential adversaries can be denied information about capabilities and intentions by identifying, controlling, and protecting generally unclassified evidence of the planning and execution of sensitive activities." [5]
The U.S. National Security Agency (NSA) used to rank cryptographic products or algorithms by a certification called product types. Product types were defined in the National Information Assurance Glossary which used to define Type 1, 2, 3, and 4 products. The definitions of numeric type products have been removed from the government lexicon and are no longer used in government procurement efforts.
The Bureau of Intelligence and Research (INR) is an intelligence agency in the United States Department of State. Its central mission is to provide all-source intelligence and analysis in support of U.S. diplomacy and foreign policy. INR is the oldest civilian element of the U.S. Intelligence Community and among the smallest, with roughly 300 personnel. Though lacking the resources and technology of other U.S. intelligence agencies, it is "one of the most highly regarded" for the quality of its work.
The vast majority of the National Security Agency's work on encryption is classified, but from time to time NSA participates in standards processes or otherwise publishes information about its cryptographic algorithms. The NSA has categorized encryption items into four product types, and algorithms into two suites. The following is a brief and incomplete summary of public knowledge about NSA algorithms and protocols.
The Federal Information Security Management Act of 2002 is a United States federal law enacted in 2002 as Title III of the E-Government Act of 2002. The act recognized the importance of information security to the economic and national security interests of the United States. The act requires each federal agency to develop, document, and implement an agency-wide program to provide information security for the information and information systems that support the operations and assets of the agency, including those provided or managed by another agency, contractor, or other source.
NSA Suite B Cryptography was a set of cryptographic algorithms promulgated by the National Security Agency as part of its Cryptographic Modernization Program. It was to serve as an interoperable cryptographic base for both unclassified information and most classified information.
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.
A restricted line officer is a designator given to a United States Navy and Navy Reserve line officer who is not eligible for Command at Sea. There are many different types and communities, including Engineering Duty Officers, Aerospace Engineering Duty Officers, Aerospace Maintenance Duty Officers, Naval Intelligence Officers, Cryptologic Warfare Officers, Information Operations Officers, Foreign Area Officers, Public Affairs Officers, Naval Oceanographers, Information Professionals, and Human Resources.
The Information Security Oversight Office (ISOO) is responsible to the President for policy and oversight of the government-wide security classification system and the National Industrial Security Program in the United States. The ISOO is a component of the National Archives and Records Administration (NARA) and receives policy and program guidance from the National Security Council (NSC).
Sensitive But Unclassified (SBU) is a designation of information in the United States federal government that, though unclassified, often requires strict controls over its distribution. SBU is a broad category of information that includes material covered by such designations as For Official Use Only (FOUO), Law Enforcement Sensitive (LES), Sensitive Homeland Security Information, Sensitive Security Information (SSI), Critical Infrastructure Information (CII), etc. It also includes Internal Revenue Service materials like individual tax records, systems information, and enforcement procedures. Some categories of SBU information have authority in statute or regulation while others, including FOUO, do not.
FIPS 201 is a United States federal government standard that specifies Personal Identity Verification (PIV) requirements for Federal employees and contractors.
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.
The under secretary of defense for intelligence and security or USD(I&S) is a high-ranking civilian position in the Office of the Secretary of Defense (OSD) within the U.S. Department of Defense (DoD) that acts as the principal civilian advisor and deputy to the secretary of defense (SecDef) and deputy secretary of defense (DepSecDef) on matters relating to military intelligence and security. The under secretary is appointed as a civilian by the president and confirmed by the Senate to serve at the pleasure of the president.
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:
NIST Special Publication 800-53 is an information security standard that provides a catalog of privacy and security controls for information systems. Originally intended for U.S. federal agencies except those related to national security, since the 5th revision it is a standard for general usage. It is published by the National Institute of Standards and Technology, which is a non-regulatory agency of the United States Department of Commerce. NIST develops and issues standards, guidelines, and other publications to assist federal agencies in implementing the Federal Information Security Modernization Act of 2014 (FISMA) and to help with managing cost effective programs to protect their information and information systems.
Managed Trusted Internet Protocol Service (MTIPS) was developed by the US General Services Administration (GSA) to allow US Federal agencies to physically and logically connect to the public Internet and other external connections in compliance with the Office of Management and Budget's (OMB) Trusted Internet Connection (TIC) Initiative.
The Risk Management Framework (RMF) is a United States federal government guideline, standard and process for risk management to help secure information systems developed by National Institute of Standards and Technology (NIST). The RMF, illustrated in the diagram to the right, provides a disciplined and structured process that integrates information security, privacy and risk management activities into the system development life cycle.
Information Operations is a category of direct and indirect support operations for the United States Military. By definition in Joint Publication 3-13, "IO are described as the integrated employment of electronic warfare (EW), computer network operations (CNO), psychological operations (PSYOP), military deception (MILDEC), and operations security (OPSEC), in concert with specified supporting and related capabilities, to Information Operations (IO) are actions taken to affect adversary information and information systems while defending one's own information and information systems.
Cyber threat intelligence (CTI) is knowledge, skills and experience-based information concerning the occurrence and assessment of both cyber and physical threats and threat actors that is intended to help mitigate potential attacks and harmful events occurring in cyberspace. Cyber threat intelligence sources include open source intelligence, social media intelligence, human Intelligence, technical intelligence, device log files, forensically acquired data or intelligence from the internet traffic and data derived for the deep and dark web.
The US Department of Commerce Office of Security is a division of the United States Department of Commerce (DOC) that works to provide security services for facilities of the department. Its aim is to provide policies, programs, and oversight as it collaborates with facility managers to mitigate terrorism risks to DOC personnel and facilities, program managers to mitigate espionage risks to DOC personnel, information, and facilities, and Department and Bureau leadership to increase emergency preparedness for DOC operations.
The Cybersecurity Maturity Model Certification (CMMC) is an assessment framework and assessor certification program designed to increase the trust in measures of compliance to a variety of standards published by the National Institute of Standards and Technology.
