WHAT IS OSINT?
In short, Open Source Intelligence (OSINT) is the practice of using the Web to create intelligence. The longer definition of OSINT is an information processing discipline that involves finding, selecting, and acquiring information from publicly available sources and analyzing it to produce actionable intelligence. In the U.S. Intelligence Community (agencies like the DoD), the term “open” refers to overt, publicly available sources, as opposed to covert or classified sources.
Many other “INTs” exist, including HUMINT, which exploits intelligence from humans via communication and interviews; and GEOINT, which is geo-spatial Intelligence gathered from satellites, aerial photography, and mapping/terrain data.
