The Nuclear Security Training and Demonstration Centre (NSTDC) at Seibersdorf enhances the IAEA’s Nuclear Security Programme, responding to requests from Member States for assistance with nuclear security challenges that require specialized technical infrastructure and equipment. The Division of Nuclear Security (NSNS) assists Member States to raise awareness of the threat of cyber-attacks and their potential impact on nuclear security by providing guidance, conducting computer security training courses and exercises, attending conferences and conducting webinars. The IAEA Member States assistance in computer security at NSTDC will benefit from integrated computer security features. The NSNS sections of Materials and Facilities (MAFA) and Materials Outside of Regulatory Control (MORC) will take advantage of an integrated information technology (IT) and instrumentation and control (I&C) infrastructure to raise awareness of computer security built into their training courses modules. This infrastructure will also be used for demonstrating cyber-attack with impacts to nuclear security facilities or to nuclear security events involving materials out of regulatory control.The objective is to train trainers and instructors (subject matter experts) on the computer security training modules specifically developed for the Nuclear Security Training and Demonstration Centre (NSTDC).The event is designed for nuclear security professionals aiming to support IAEA computer security trainings for nuclear security. It involves appropriation of IAEA demonstrations and hands-on exercises. Therefore, participants must have a good knowledge of IAEA computer security guidance.?The event is open to 30 participants and will be held regularly.
