SIGINT

SIGINT may refer to any of the following:

1. Short for signal interrupt, a SIGINT is a signal sent to the processor, requesting an interrupt of the current process in the terminal. For example, the user can send a SIGINT while in a terminal or pseudo-terminal by pressing Ctrl+C.

2. Signals Intelligence, often abbreviated as SIGINT, is the interception, collection, and cryptanalysis of transmitted information. One type of SIGINT is known as COMINT (communications intelligence), which is the interception of communications between people. The other is known as ELINT (electronic intelligence), which is the interception of electronic signals not directly used in human communication. Examples of a SIGINT organization is the National Security Agency and Unit 8200.
