Security, Privacy, and Trust in Cyberspace

Our world is at a pivotal moment where the boundaries dividing the physical and social worlds from the cyber world have become blurred. Cyberspace has evolved from an interconnected digital environment into a complex and interdependent cyber ecosystem that involves hardware, software, networks, data, people, organizations, countries, and the physical world. Critical functions of everyday life are deeply intertwined with computing, including health, government, commerce, the public sphere, education, critical infrastructure, interpersonal communication, and transportation. The complexity and inter-dependencies in cyberspace can be misused and exploited by malicious actors. These in turn can trigger adverse outcomes such as disruption of critical infrastructure and systems; theft of intellectual property and sensitive data; amplification of inequalities; disclosure of private information of individuals, organizations, and governments; and threats to lives, livelihoods, and reputations. Furthermore, constant attacks on the data and assets of corporations, governments, and individuals undermine people’s trust in decision-making and processes that depend critically on these cyber systems.
