Worldwide attention is being given to a new security threat, in the form of global terrorism. This book presents the position that the online environment is a significant and relevant theater of activity in the fight against terror, and identifies the threats, the security needs, and the issues that are unique to this environment. The book examines whether the unique characteristics of this environment require new legal solutions, or whether existing solutions are sufficient. Three areas of online activity are identified that require reexamination: security, monitoring, and propaganda. For each of these, the book indicates the issues, examines existing legal arrangements, and offers guidelines for formulating legal policy. There is a demonstrated need to relate to the digital environment as a battlefront, map the new security threats, and thereby hope to provide focus to the pressing discussion on today's legislative and technological agenda.
