"MPLS security analysis," Chapter 3 of CCNP Self-Study: Building Cisco Multilayer Switched Networks, 3rd Edition by Richard Froom, Balaji Sivasubramanian and Erum Frahim, describes how MPLS provides security (VPN separation, robustness against attacks, core hiding, and spoofing protection), how the different Inter-AS and carrier's carrier models work, and how secure they are compared to each other. It discusses which security mechanisms the MPLS architecture does not provide and how MPLS VPNs compare in security to ATM or Frame Relay VPNs.
