All security interested individuals should save SANS resources and constantly
incorporate it into their workflow. Guys over at SANS are best of the best in
terms of information security content; some develop tools, others share
information for the general public, they even have classes you can take over
there (really expensive though, have the government/work pay for it :D).
As a starter anyone who needs quick links to SANS resources can check out:
