A practical guide to hardening MPLS networksA Define "zones of trust" for your MPLS VPN environment Understand fundamental security principles and how MPLS VPNs work Build an MPLS VPN threat model that defines attack points, such as VPN separation, VPN spoofing, DoS against the network’s backbone, misconfigurations, sniffing, and inside attack forms Identify VPN security requirements, including robustness against attacks, hiding of the core infrastructure, protection against spoofing, and ATM/Frame Relay security comparisons Interpret complex architectures such as extranet access with recommendations of Inter-AS, carrier-supporting carriers, Layer 2 security considerations, and multiple provider trust model issues Operate and maintain a secure MPLS core with industry best practices Integrate IPsec into your MPLS VPN for extra security in encryption and data origin verification Build...
