Open-source intelligence (OSINT) is intelligence collected from publicly available sources. In the intelligence community (IC), the term "open" refers to , publicly available sources (as opposed to covert or clandestine sources); it is not related to open-source software or public intelligence.
OSINT includes all publicly accessible sources of information, such as:
OSINT is distinguished from research in that it applies the process of intelligence to create tailored knowledge supportive of a specific decision by a specific individual or group.
OSINT is defined by both the U.S. Director of National Intelligence and the U.S. Department of Defense (DoD), as "produced from publicly available information that is collected, exploited, and disseminated in a timely manner to an appropriate audience for the purpose of addressing a specific intelligence requirement."

Open-source intelligence under one name or another has been around for hundreds of years. The significance today of OSINT in the USA is the conflict between military, government, and the private sector as to how the bulk of intelligence should be obtained. With the advent of instant communications and rapid information transfer, a great deal of actionable and predictive intelligence can now be obtained from public, unclassified sources.
OSINT is especially helpful in addressing global coverage, a term encompassing all of the countries and topics that are not considered by the secret or national security worlds to be "vital."
Accredited journalists have some protection in asking questions, and researching for recognized media outlets. Even so, they can be imprisoned, even executed, for seeking out OSINT. Private individuals illegally collecting data for a foreign military or intelligence agency is considered espionage in most countries. Of course, espionage that is not treason (i.e. betraying one's country of citizenship) has been a tool of statecraft since ancient times.
