hello everybody..I am relatively new to the security scene and i see that there is a wealth of information out there. In fact there is too much. There is so much information that i dont know where to begin to learn about it. I started by learning linux fairly well, but whats next? I know i can always take a course or something but that costs money. With all the FREE information (I'm all about opensource!!), i want to take full advantage of it. Can anyone suggest some structure or outline that i should go about learning about security?

Thanks in advance
