Common Types of Intelligence Gathering

Intelligence gathering encompasses several key disciplines. Some of the more common forms are:

Human Intelligence (HUMINT): This involves collecting information directly from human sources. Methods range from overt techniques like interviews to covert operations such as espionage.

Signals Intelligence (SIGINT): This focuses on intercepting and analyzing electronic signals. A subcategory of SIGINT is Communications Intelligence (COMINT). Specifically, this involves intercepting communications between individuals or groups. SIGINT collection platforms include ships, aircraft, ground stations, and satellites.

Imagery Intelligence (IMINT): Also known as photo intelligence, IMINT utilizes visual data. Its historical roots trace back to aerial observation during the American Civil War, with significant advancements during World Wars I and II. Today, satellite imagery plays a crucial role in IMINT.

Open-Source Intelligence (OSINT): This involves gathering and analyzing publicly available information from diverse sources. These sources include:
