Intelligence services are government agencies responsible for gathering, analyzing, and disseminating information related to national security. They monitor potential threats, such as terrorism or espionage, and provide insights to help policymakers make informed decisions. These agencies often work both domestically and internationally to protect a nation's interests. The work of intelligence services involves various methods, including surveillance, human intelligence (HUMINT), and signals intelligence (SIGINT). They collaborate with other organizations, such as law enforcement and military units, to ensure a comprehensive approach to security. Overall, their primary goal is to safeguard the nation and its citizens from potential dangers.
