Analyze the technical, legal, and financial ramifications of revolutionary and controversial network strikeback and active defense techniques. Follow the travails of eight system administrators who take cyber law into their own hands. See chillingly realistic examples of everything from a PDA to the MD5 hash being used as weapons in cyber dog fights. There is a certain satisfaction for me in seeing this book published. When I presented my strikeback concept to the security community years ago, I was surprised by the ensuing criticism from my peers. I thought they would support our right to defend ourselves, and that the real challenge would be educating the general public. It was the other way around, however. This is why I`m happy to see Aggressive Network SelfDefense published. It shows that people are beginning to consider the reality of today`s internet. Many issues are not black and white, right or wrong, legal or illegal. Some of the strikeback approaches in this book I support. Others, I outright disagree with. But that`s goodit gives us the chance to truly think about each situationand thinking is the most important part of the security business. Now is the time to analyze the technologies and consider the stories presented in this book before fiction becomes reality.Timothy M.
