Version 4.1 - 5.10 Secure access gateways
I really don't like the way this section's subtopics are laid out. It's like having a topic of Seafood dishes that has subtopics of Salmon, Trout, Lemons. [Why was PKI just plopped in there?] On top of that, you have SSL VPN - but then you have section 6.6 which covers VPN Solutions and does not list SSL VPN. So despite the organization not making sense, I'm going to just go with it knowing that the topics are at least covered somewhere.
