Understanding UN Security

The United Nations Security Management System (UNSMS) enables the activities of UNSMS organizations within acceptable levels of security risk. The UNSMS unites over 50 member organizations, with a primary objective of facilitating the operations of these entities while maintaining an acceptable level of security. Fifteen of these members serve as key decision-makers within the Inter-Agency Security Management Network (IASMN), which is an integral part of the UNSMS. Within this framework, the UNSMS plays a pivotal role in guiding, supporting, and acting as recipients of the UN Department of Safety and Security (UNDSS) services.
