The RBOC (Resilience Beyond Observed Capabilities) Network Plus is designed to create new knowledge, new capabilities and new opportunities for collaboration to help the UK prepare for security threats in the coming decades. The starting point is a scenario of a catastrophic attack on digital and energy networks in the year 2051. RBOC N+ will convene some of the UK's leading experts in engineering, physical sciences, mathematics, health sciences, social and behavioural sciences, arts and humanities, and cross-disciplinary topics such as AI, security studies and urban planning, together with government and industry, to refine, deepen and test this scenario and to use it to create immersive simulations .
