Grey Hat Hacking is already a way ahead for a newbie in the linux & infosec world ;-)
there are tons of books...
BUT hacking is not about reading books, understanding various basics through all layers (technologies, processes & people), using security tools based on you tube/hak5/vimeo video tutorials..it's about all about curiosity in the infosec space and diving deeper into these 3 main layers...
Hacking for fun and NO profit!
...without 'Hackers', we wouldn't be at this stage of technology!
...contribute to the community, attend on events, learn the basics, understand what's running under the hood and not blindly following the mass !
