Dear past self, this book is poorly written, inaccurate and a waste of reading time, go read "Cyber War Will Not Take Place" by Thomas Rid instead.
The authors appear to have some knowledge of pen-testing tools but beyond their area of expertise they paraphrase what others have said while injecting their own mistakes. Many military writers don't seem to understand, or to have actually read Clausewitz, so I'm willing overlook their misuse of his ideas but confusing "the World Wide Web" with "the Internet", as the authors do in this book, is not acceptable.
'Introduction to Cyber-Warfare' contains many grammatical, logical and factual errors. It reads like a self published book, perhaps the copy-editors at Syngress Press were all sick the week this was published.
Beyond pseudo-military posturing (1980's Cinema called and they want their Cyber-Warriors back*), 'Cyber-warfare' fails to examine its subject matter.
* Yes I know this is a real term used by some folks in the Pentagon. Please don't encourage them.
