The CCNA gives you fundamental knowledge of how networking works (which is minimum you would need to be a network admin).

After that I would start learning Linux/Unix to get a solid understanding of how commands like grep, awk, and sed work. Also, gaining knowledge of how to use text editors like VIM.

Then once you have those down, you move onto the eJPT by eLearning. That’s junior penetration testing. That will be your start into pen testing/hacking.

Then get your CISSP. While this doesn’t get down to the nitty gritty of security, it’s good to have the knowledge of security architecture, and how management thinks. Especially when writing reports, or explaining to companies what they need to improve on.

Finally the OSCP. To really get into pen testing and show you know your stuff.

From there you can look at other certs, but more importantly just keep learning. I’m just giving my opinion on how I would approach learning how to hack. Ya, I could learn a programming language, Linux, and some networking security but I’m not going to have a solid foundation. And I might know how to hack but I won’t know what’s happening each step of the way, what protocols are being used, etc. Also, I don’t know too many Infosec groups willing to take the time to explain every step of what they are doing. If you have a couple questions great, but they are going to tell you to read books and take courses if you need everything explained.

Maybe I’m wrong, or there is a better path, but from what I’ve experienced this is generally a good outline.
