Advanced collection and analysis techniques I’m new to OSINT, and I’ve been reading « The not yet exploited goldmine of OSINT » book. In the intro, the defined OSINT as « Given some input data, together with the application of advanced collection and analysis techniques, OSINT continuously expands the knowledge about the target. In this way, the information found feeds the gathering process again to get closer to the final goal »
What are the techniques of advanced collection and analysis? (Excuse my bad English).
