A comprehensive introduction to VPNs and networking basics, this book provides readers with a solid foundation of networking basics and the understanding necessary for learning the complexities of the VPN technology that follows. It takes the reader through the actual steps involved in provisioning the hardware, software and set-up with the provider of services for Internet access and communications carriers, thus leading to a comprehensive understanding of all VPN protocols. There is also detailed information about securing VPNs, including information on intrusion detection. Readers gain an understanding of security, encryption, encapsulation, key management and intrusion detection systems, all necessary for a secure network. Networking blueprints for 4 different types of VPNs, including IPSec and PPPT are also included.
