The Internet has dramatically altered the landscape of crime and national security, creating new threats, such as identity theft, computer viruses, and cyberattacks. Because cybercrimes are not often limited to a single site or national border, crime scenes themselves have changed. Consequently, law enforcement itself must confront these new dangers and embrace novel methods of prevention, as well as produce new tools for digital surveillance - which can jeopardize privacy and civil liberties. Cybercrime brings together leading experts in law, criminal justice, and security studies to describe crime prevention and security protection in the electronic age. Ranging from new government requirements that facilitate spying to new methods of digital proof, the book is essential to understand how criminal law - and even crime itself - have been transformed in our networked world.
