Its impossible to mitigate threat if you can't first identify and articulate it to corporate leadership. This book by Bill Boni and Jerry Kovacich serves that function well and should earn a place on the bookshelves of all those involved in driving e-commerce as well as those responsible for computer network defense. Read it, use it to understand adversary threat (whether it be economic, industrial or military), understand its message, and learn from the real-world case studies.
