Intelligence gathering is a critical aspect of national security, and the government uses many different techniques and methods in their intelligence gathering.

Two primary approaches to gathering intelligence are human intelligence (HUMINT) and signals intelligence (SIGINT). While both methods are used to collect valuable information, they collect it in completely different ways.
Human Intelligence (HUMINT)
HUMINT relies on human operatives to gather information through direct interaction with individuals, organizations, or groups. Operatives might be intelligence officers, spies, informants, or even diplomats. They use techniques like espionage and interrogation to gather information and use it to their advantage.
One benefit of HUMINT is the real-time nature of the information being gathered. However, HUMINT comes with a higher risk for the operatives involved. The very nature of this type of intelligence gathering puts operatives at a greater risk of being discovered.
Signals Intelligence (SIGINT)
SIGINT, on the other hand, focuses on intercepting and analyzing electronic communications, such as radio signals, emails, phone conversations, and internet traffic. This form of intelligence gathering primarily involves technical methods such as electronic surveillance, cyber espionage, and electronic traffic analysis. Information can be gathered from weapons systems, radars, or even through network infiltration.
While humans are still heavily involved in gathering and analyzing the information, there are fewer risks to the individuals themselves since operations are often conducted remotely.
Other types of intelligence gathering
There are also other intelligence gathering techniques that focus on gathering information from different sources. For instance, Open Source Intelligence (OSINT) involves collecting information from publicly available sources, such as newspapers, social media, or academic journals. Geospatial Intelligence (GEOINT) gathers data from satellite imagery, maps, and aerial photos, while Technical Intelligence (TECHINT) involves collecting data about enemy weapons and developing countermeasures.
Intelligence gathering techniques use a wide range of methods which vary based on the target information. Combining techniques gives the government a well-rounded picture of enemy movements and allows us to make more informed decisions across the complex spectrum of national security.
