Hi spoonyG
First of all Welcome to

I totally agree with
blackazarro, The first step in ethical hacker / network security is mastering
TCP/IP Concepts. The book I would suggest is:
Richard Stevens' TCP/IP illustrated.
Published by Addison-Wesley.
Volume 1 - describes the TCP/IP protocols.
URL:
http://www.amazon.com/exec/obidos/ASIN/0201633469/tcpipresourcesVolume 2 - describes the TCP/IP stack as implemented in 4.4BSD-Lite, at the source code level.
URL:
http://www.amazon.com/exec/obidos/ASIN/020163354X/tcpipresourcesVolume 3 - describes HTTP, NNTP, and more.

Request for Comments (RFC). The Requests for Comments form a series of notes, started in 1969, about the Internet (originally the ARPANET). The notes discuss many aspects of computer communication, focusing on networking protocols, procedures, programs, and concepts but also including meeting notes, opinion, and sometimes humor. RFCs are available at
http://www.ietf.org/rfc/.
Mastering the
Operating System Concepts and the various Operating Systems (both Windows and Linux) is the next step I would suggest. A good practical working experience on these operating systems (at the administrative and user level) gives a good grip on the various security issues related to ethical hacking.
Once you have a good understanding of the above topics, you can slowly move on to some
languages - the one I suggest is C and Perl. Parallel to this, you can start working on various other
technologies like IDS, honeypots, honeynets, forensics, Routers, switching concepts, firewalls, etc.
Last but not the least, keep learning, keep updating the technologies that you have mastered,
Knowledge is gained when it is shared, so keep sharing your expertise and knowledge here so that we all can learn from you.
Stay secure and Happy hackingManu Zacharia - (morpheus063)
