Now, however, the President's Daily Brief and other crucial intelligence reports often rely less on secrets from risky espionage missions than on material that's available to just about anyone.
"Open-source" information is becoming part of intelligence gathering as analysts turn to Internet sources of information.
Such material is known as "open-source intelligence" or, in the acronym-laden parlance of the 16 federal agencies that make up the U.S. intelligence community, OSINT. The explosion of information available via the Internet and other public sources has pushed the collection and analysis of that material to the top of the official priority list in the spy world, intelligence officials say.
Federal commissions repeatedly have criticized the intelligence community for not moving more quickly and aggressively to exploit open-source information.
Every potentially useful nugget must be vetted because enemy states and terror groups, such as al-Qaeda, sometimes use the Internet and other open channels to put out misleading information.
The CIA has set up an Open Source Center, based in a nondescript office building in suburban Washington, where officers pore over everything from al-Qaeda-backed websites to papers distributed at science and technology symposiums, says Douglas Naquin, the center's director.
Other agencies, such as the FBI and the Defense Intelligence Agency, are training scores of analysts to mine open sources and giving many of them desktop Internet access
national security officials also are grappling with the flip side of the open-source phenomenon: making sure sensitive information held by the government, businesses and even individuals doesn't slip into the same sort of public outlets that U.S. intelligence agencies are scrutinizing.
Open sources can provide up to 90% of the information needed to meet most U.S. intelligence needs
Open source now has a new meaning -- the traditional term has meant "open source software" but now, increasingly it is meaning "open source information" -- as US spy agencies are talking about the use of more open source information, or information taken from openly available and free sources on the Internet.
As we teach new terminology and how to understand the words that make our world meaningful, it is increasingly important to teach students to watch and understand the evolution of language. This is an excellent case study.
This is also an important term and article to be reviewed by students involved in the Horizon project that are analyzing government trends and our changing world.
This new term of open source information is a very important emerging trend that should be included in the subgroup of those analyzing government information and trends.
