Regarding security links, I guess you didn't see the seventh thread
from the top of this forum. One of the LQ moderators, unSpawn has done a great job of collecting the best links, and he continues to update it. I don't know why it's so hard to see, but every couple of weeks someone asks this same question.
And as far as a secure distro, every distro has exploits that may or may not be known presently. Some one will find an exploit today, tomorrow, or the next day. So the most secure distro is one that you work on keeping secure.
 Doh! just saw your edit (right under all the flashing doo-dads in your sig) [/edit]
