This NucSecCyber Webinar was held on February 17, 2021 (Wed) at 14:00 Vienna time (UTC+01:00)Nuclear Power Plants (NPPs) are among the most complex energy systems ever built and their design and operation increasingly relies on a myriad of computer-based systems. Therefore, computer security for nuclear security is a critical concern that requires research attention. To enable this research, participants in the Coordinated Research Project (CRP) “Enhancing Computer Security Incident Analysis at Nuclear Facilities” developed testbeds that are representative of NPP environments. These activities were centered on a hypothetical and technology-neutral Pressurized Water Reactor (PWR) facility, called Asherah, which was defined based on several existing NPP designs.To be able to examine the facility impacts of cyber-attacks to nuclear facilities, one of the major CRP products is the Asherah NPP Simulator (ANS) that was specifically designed for cyber security research and training with software- and hardware-in-the-loop capabilities. ANS also allows, for example, the investigation of threat scenarios, measuring the effectiveness of defensive computer security measures, and the assessment of the facility impact of a system being compromised.In this webinar, researchers will present the main simulation tools and testbeds that have been developed by the CRP team to support the IAEA and Member States’ immersive research and training activities in computer security for nuclear facilities.?Speakers:Deeksha GuptaRicardo Paulino MarquesJae-gu Song?
