A world without the advantages and convenience provided by cyberspace and the internet of things is now unimaginable. But do we truly grasp the threats to this massive, interconnected system? And do we really understand how to secure it? After all, cyber security is no longer just a technology problem; the effort to secure systems and society are now one and the same. This book discusses cyber security and cyber policy in an effort to improve the use and acceptance of security services. It argues that a substantive dialogue around cyberspace, cyber security and cyber policy is critical to a better understanding of the serious security issues we face.
