When you purchase The Hacker's Play Book, be sure to check the online links for updated information. It continually updates and changes. There are an onslaught of good books from which to choose.
Here's A List That Helped Me: The Hackers Playbook 3, Hacking: The Art of Exploitation (check for latest Edition and updated links in book), The Web Application Hacker’s Handbook: Finding and Exploiting Security Flaws, Penetration Testing: A Hands-On Introduction to Hacking----------Books For Reference: RedTeam Field Manual, Blue Team Manual------------Books For Programming Hacking: Black Hat Python, Grey Hat Python.
There is also the route of certifications. In regards to the them, many speak condescendingly. However, the right prep-courses, books and labs you could pass in just over a month. As a major benefit of obtaining the certifications, you gain strong foundations!
Recommendation For Certs.: Security +, Network +, and your C.E.H., when you obtain the needed experience and proctor. Another cert. you can look into are those provided by Offensive Security(Kali).. Get those and see where you would like to specialize. "Cyber Security" and "Information Security" are massive field/s. Find your calling within it.
Hope this helped a little. Good luck with your future decisions!
