Shin Bet, officially known as the Israel Security Agency (ISA), is Israel's internal security service. Established in 1949, its primary mission is to protect the state from threats such as terrorism, espionage, and subversion. It operates mainly within Israel and the Palestinian territories, focusing on intelligence gathering and counter-terrorism efforts. The agency works closely with other security organizations, including the Israel Defense Forces (IDF) and Mossad, Israel's foreign intelligence service. Shin Bet plays a crucial role in maintaining national security by monitoring potential threats and conducting operations to prevent attacks against Israeli citizens and interests.
