Hayabusa - Thanks for your input. With regards to protocols I believe what you say about knowing the way things work in depth. I guess what I should start doing is learning how everything works at a deep level before I start worrying about how to break it in any significant way, as many security targeted books and courses will let me do. Without solid foundations any knowledge I gain will always have lots of holes that need fixing.
On that note, after TCP/IP - and then I'm assuming in depth knowledge of Windows & Linux, would you recommend any particular area? If nothing comes to mind don't worry, I imagine I've just flippantly given three area's with a huge amount of information in them which will take me quite a while to get through and bring up 10's of questions I will need to continue answering on my own

With certifications I'll defiantly check out eCPPT. I don't "need" certs in the sense I'm happy in the field I am currently in, but I find I learn well with a structured framework so I'll still look into it. Pen testing sounds the most fun
but who knows with experience I may learn to enjoy something else! Thank you for your awesome response. cd1zz - Thanks for breaking it down for me like that. It's just what I was after. Helps me see what area's are really useful and what are the 'core' foundations to pen testing. Don't get me wrong, I appreciate that ALL area's of knowledge are definitely useful, but with everything some are used more than others. I'll definitely be focusing on networking and web applications (TCP/IP study ftw!)
ajohnson - Just a range of VM machines I've set up myself. Windows XP, Metasploitable / Metasploitable v2, De-ICE Challenges, OWASP BWA - the basics. I'll check out what other labs people have set up and take that on board for what I can integrate myself
Thanks for your reply. m0wgli - Thanks for the links, I'll definitely check them out!
Thanks again everyone, really appreciate the quality posts and it helps me a lot more with the directions I'll be taking (Networking / Web App focus, studying the knowledge in depth first before worrying about security concerns, then studying security aspects while testing out practical knowledge in a VM lab.)
Cheers!






I promise I have.
