Got any Suggestions? I'd like to delve deeper into the topic to bring my knowledge base up.

This is what I've got so far:

Hacking Exposed 6 (10th Anniversary Edition) by; McClure, Scambray, and Kurtz
Hacking: The Art of Exploitation 2nd Edition by, Jon Erickson
Steal This Computer Book 4.0 by, Wallace Wang
Any my trusty Security+ Study Guide and Labsim Component. (Of which I passed the certification for, though I'm still waiting for the certificate in the mail.)

Any book suggestions? Sites? Programs?
I'd like to hear whatever you've got to say.

Thanks in advance.

P.S. SSCP and CISSP books would also apply, since I've not found any. (Though I do not qualify to get those certifications.)
