OSINT Education Spotlight: Mediums of PAI

The following four mediums represent the totality of the PAI environment at this time. As the discipline evolves, additional mediums may be added. The examples provided should not be viewed as a comprehensive listing but rather selective examples to aid in comprehension. The mediums are ordered chronologically even though the Practitioner Committee acknowledges that digital is the largest and most common medium. While most OSINT practitioners focus on digital exploitation, a working knowledge of the other PAI mediums is essential. As commercially available information (CAI) is a subcomponent of PAI (see OSINT Foundation OSINT Definitions document), the following also applies to CAI.

The mediums listed are not the content themselves, but rather the means by which the content is delivered. The Shannon-Weaver Communication Model breaks down the communications process into its characteristic parts and attributes. The channel or medium is how the audience sees, feels, hears, or experiences (via a particular technology) the message.
