This NucSecCyber Webinar was held on September 22, 2021 (Wed) at 14:00 Vienna time (UTC+01:00)Nuclear facilities and operations rely upon complex networks of suppliers, vendors and integrators with multiple tiers of globally dispersed suppliers throughout the supply chain life cycle. This network includes designers, developers, contractors, manufacturers, integrators, solution providers and logistics providers (including shippers, carriers and customs agents). The complexity of these networks provides numerous possibilities for an adversary to compromise a service or device, or to acquire system information prior to use within a facility or organization within the nuclear security regime.This webinar will present the critical issues? and mitigation techniques for supply chain, which introduces the countless attack vectors through the many entry points (touchpoints) through the design, hardware and software development, testing, transportation, installation, operation, maintenance and decommissioning.
