Signal intelligence, popularly known as SIGINT is all about the blocking or interfering with signals that are in progress with the primary aim being to gather information. Most decisions that are as a result of intelligence are usually crucial for operations in various bodies. A good example is a military which relies so much on information to carry out most of its activities.
There are also other intelligence bodies from various parts of the world that rely on SIGINT. It is divided into several fields of study related to it which include COMINT (Communications Intelligence), FISINT (Foreign Instrumentation Signals Intelligence) and ELINT (Electronic Intelligence).
The use of this type of technology can be traced back to the early days when most militaries used to block radio communications of their enemies or rivals during a war. Other used related technologies like cryptography to minimize the chances of their signals being detected.
Intelligence gathering has witnessed rapid improvements over the recent years, thanks to advancements in technology. Most militaries are now using crewless aerial vehicles like drones to gather what may be important for their warfare or safety. Through signal intelligence, it is easy to identify who a specific target is communicating with, their location, relationship, and activities without getting noticed easily. There are several benefits that come with the use of signal intelligence. They include:
The use if signal intelligence can help enhance public safety. Bodies tasked with intelligence gathering can get valuable information through this type of technology and alert the public. They can be warned against any impending attacks or disasters that will help everyone stay vigilant and ensure they are safe.
Through signal intelligence, the relevant party will always be aware of the different situations. A good example is when intelligence bodies in the military monitor calls of any planned attack by their enemies. They will always be aware of what is about to them in advance, and this will help them get ready for the attack.
Intelligence bodies can use this type of technology to track criminals or people who have committed a crime in specific areas. It is also easy to foil any crime or terror activity using this type of technology. Anybody who has committed or plans to engage in any criminal activity will be tracked to their hideout.
