SIGINT

SIGINT, or Signals Intelligence, refers to the collection and analysis of information from electronic signals and communications. This includes data from phones, emails, satellites, and radio transmissions. Governments and organizations use SIGINT to gain insights into activities, intentions, and capabilities of adversaries, as well as to secure their own communications. It plays a crucial role in national security, defense strategies, and intelligence operations, helping to identify potential threats and inform decision-making. Essentially, SIGINT helps to "listen in" on communication to understand what is happening in the world around us.
