Management of cyber security is challenging. Cyber security professionals tend to take a rather skewed approach in dealing with security issues. Clearly there is no right or wrong path to choose. An exclusive reliance on technical measures ignores the governance aspects that are so important. Incorporating governance may result in ignoring the cultural and normative issues. It is usually not about choosing one over the other. It is about defining a holistic perspective to management of cyber security. This book covers an interesting range of topic areas. These include cyber stalking, cyber fraud and abuse; denial of services; cyber espionage; cryptography, security policies; cyber terrorism; cyber detection and forensics. Ethical and intellectual property issues are also discussed. The book culminates with case studies. Cases allow students to apply and contextualize the concepts.
