Ethical Hacking and Penetration, Step by Step with Kali Linux

It's okay - This book is great for beginners who aren't familiar with where to start in cyber security, but know they want to do pentesting content. That being said, in my opinion it's not worth the money. All of this content can easily be found on site like Medium, and doesn't offer any in-depth context on how to do things like finding Zero Day exploits. It's all surface content that most people will pick up just by doing Google searches. Rather than putting money into books like these, look at taking online classes threw Google, Microsoft, etc. to actually learn real cyber security, and pentesting content. You can also take classes threw OffSec themselves (the company that made Kali Linux).

I bought this book last night ( 12/20/22 ) I got into the first chapter. Suddenly, it vanished from my library and now I have to repurchase it? it doesn't make any sense. I also have the receipt.

Good value for money The book is a good value for money. It has some conceptual information at the beginning and introduces some good Kali tools later in the book. There is not lot information about commands options or detailed parameters but that's cool with me as I can always refer to the commands help and read. The important thing for me was to get an idea about tools and how they work and this book perfectly delivers that. It is probably not a book for high school students with no network or security background but if you have some basic knowledge, you can figure things out! In summary, it is a well worth read and recommended.
