This IS where you start to understand it all!
Format: Paperback
While I haven't received my Second Edition book yet I do have the First Edition and I can say it's very thorough and well explained to even the beginner level. If you're trying to learn both Linux and Cybersecurity this IS the place you want to start. It will save you a ton of headaches and you're getting VERY VALUABLE skills you can use in any scenario. I would call it an advanced starting point. Linux itself can be somewhat difficult and daunting to learn and understand if you're coming from a strict use (Windows in my case) OS 25+ years. This book bridges that gap effectively and you can absorb the knowledge with a little work. Also watching OTW's video on YouTube with David Bombal is an excellent follow along source. In my opinion, OTW does the best job of explaining exactly what you need to know. And follow it up with a video or two of how to understand the Linux file system and you'll soon be set to go. David Bombal's vids on setting up VM on your computer are also very helpful!
If your intention is to get into Cybersecurity from zero knowledge this IS the best point to gain valuable knowledge whether it's to crack into IT, Cybersecurity or just for your own knowledge, this book is worth 10x it's price!
