MPLS VPN Security (Networking Technology)

A very good examination of MPLS security that goes way beyond "its just like Frame Relay". The authors do an extremely deep dive on those aspects of MPLS technology that may effect the security of carriers who run MPLS or enterprises who utilize MPLS services.

This is one of the few books I've seen that starts off with a discussion of just what is secure. Secure from the casual hacker that might try to get into your network is one thing.
