Supportive government policy, a strong research base and history of industrial success place the benefits of an emerging digital society. Protecting benefits and minimizing risks requires reliable and robust cyber security, backed by a robust research and translation system. Trust is essential for growth and maintenance of participation in the digital community. Organizations gain trust by acting in a trustworthy way leading to building reliable and secure systems, treating people, their privacy and their data with respect, and providing reliable and understandable information to help people understand how safe they are.
