Good introductory book on information security
Format: Paperback
As mentioned in my review title, this is a good introductory book on information security. I would like to stress the "introductory" part since anyone who is already in the field or otherwise highly technical should probably avoid this book. Otherwise, for anyone just starting out in information/cyber security or otherwise curious, this will be a nice easy intro into an interesting subject.
