Read reviews and bought this book. The 5 stars are mostly bots or fake reviews. This is out-dated book, leads reader to purchase/use service and commit security errors possibly compromising their computers/devices. Some of none-spam like content is ok definitions of cyber terms but more of this book is junk.

Actually it's a good knowledge given ebook and the things which are old but useful. Some data is not works eventually it's good information and good concept.

Horrible English, broken sentences. And that was just the first 5 pages. I understand the author is not a native English speaker, but this was hard to read.
