Internal security is the act of keeping peace within the borders of a sovereign state or other self-governing territories, generally by upholding the national law and defending against internal security threats. This task and role differs from border security. Responsibility for internal security may range from police to paramilitary forces, and in exceptional circumstances, the military itself.
