Mastering Linux Security and Hardening: Protect your Linux systems from intruders, malware attacks, and other cyber threats, 2nd Edition

Great book, read in a little under a week. Yes the book may be a little on the beginer side, but I honestly learned a lot even with being in IT for a year. A lot of the book covers REHL and Ubuntu but most of it can be applied else where as it goes over key concepts.I found 3 spelling errors and one sentence that i belived got cut off or the author could not finish their thought.I recomend this book if your getting in to security, or want to secure your server as its a good place to start.
