where and what on Network Security?

register with www.cramsession.com. They have lots of study guides.

Else, go to Cisco, Microsoft.com/security, Sans.org, NIST.gov

That'll keep you reading for a few months

http://neworder.box.sk

Go to their articls section and start reading.

You can also start by picking various books at
the book store. O'Riely has one titled, Network
Security. You can also go to
http://www.cert.org/tech_tips/home_networks.html
which has a lot of information.
www.sans.org is also a good one.
Good luck.

www.sans.org has hundreds of security papers on dozens and dozens of topics. I highly recommend their GSEC program as a good starting point for a savy administator to become security aware. The SGEC program covers the entire gamut of computer security issues. There are second level more advanced courses beyond the GSEC course available too.
