Open Source Intelligence
The term “open source” refers in particular to records this is publically available. A huge part of the internet cannot be found using major search engines. This is called as “Deep Web”. Deep Web is a mass of websites, databases, files, and more that cannot be indexed by Google, Bing, Yahoo, or any other search engine. Despite this, much of the content of the dark web can be considered open source because it is easily available to the public.
