SIGINT, or Signals Intelligence, refers to the collection and analysis of electronic signals and communications. This includes data from various sources such as phone calls, emails, and radio transmissions. Governments and military organizations often use SIGINT to gather information about potential threats and to monitor activities of interest. The process involves intercepting signals, decrypting them if necessary, and analyzing the content for actionable intelligence. SIGINT plays a crucial role in national security, helping to inform decision-making and strategic planning. It is one of the key components of intelligence operations, alongside other forms like HUMINT (Human Intelligence) and IMINT (Imagery Intelligence).
