NSA Surveillance refers to the monitoring and collection of data by the National Security Agency, a U.S. government agency. This surveillance aims to gather intelligence to protect national security and prevent threats, including terrorism. The NSA uses various methods, including electronic communications and internet data, to track potential risks. The program has raised concerns about privacy and civil liberties, as it often involves collecting information from ordinary citizens without their consent. Critics argue that such practices can lead to overreach and misuse of power, while supporters claim they are essential for maintaining safety and security in a complex world.
