Mitigating the Insider Threat

As an International Community of Practice

An insider has been involved in every case of nuclear or radioactive material theft. Our international and multi-sector community shares ideas, best practices, and expertise to understand and mitigate this threat to international nuclear security. In doing so, we provide resources, host events, and gather for an international symposium every three years.

Over 30 nations participate in our community of practice.

Advancing Nuclear Security

Insiders pose a significant threat to nuclear and radiological security, as they generally possess access rights which, together with their authority and knowledge, grant them far greater opportunity than outsiders to bypass dedicated nuclear and radiological security elements.

Mitigating Insider Threats

Following the 2016 Nuclear Security Summit, the U.S. sponsored a Joint Statement on Insider Threat Mitigation, which is now known as IAEA Information Circular 908 (INFCIRC/908). Since then, dozens of countries have endorsed the Joint Statement and are advancing the state-of-practice of mitigating insider threats for nuclear security.
