Hacker******************

This book is very useful for people who want to understand hacker attacks and prevention. It is comprehensive in content and covers many aspects, such as system vulnerabilities, Trojan viruses, online information protection, etc. Through case teaching, readers can better understand and master this knowledge. Moreover, the layout of the book is very compact, with pictures and texts, making it easy to read. I feel that the author must be an expert in this field to explain complex knowledge so clearly and easily. All in all, I think this is a great book worth recommending!
