Some of the best information you can have on a topic comes from those who have been there and done that. In the “Tribe Hackers” series of books by Marcus Carey and Jennifer Jin, the perspectives of those who have worked in cyber security are provided via interviews with 70 professionals whose advice is practical, not just theoretical.
Not only does this book help to answer some loftier questions, it also addresses more basic questions such as how to get started in cyber security and what education is needed to do so.
For anyone just starting to be interested in the field but doesn’t have in-depth knowledge, this is a great starting point.
In addition to the information and words of wisdom, the authors provide contact information for these experts if you want to find out more from any of them.
