In this 1-day Masterclass, we seek to stimulate a constructive discussion about the objectives and requirements for cyber governance for the Corporate Board by asking, “What sort of governance mechanisms and institutions can lead to effective oversight and management of threats to cyber security? What sort of decision-making, leadership, mandate and authority will be effective?” By the same token, we also ask: “What threats to cybersecurity can undermine the evolution of governance for cyberspace? Which classes of actors need to be involved in mitigating this process?”
