内容説明
VPNs enable any enterprise to utilize the Internet as its own secure private network. In this book, two leading VPN implementers offer a start-to-finish, hands-on guide to constructing and operating secure VPNs. Going far beyond the theory found in most books, Ruixi Yuan and Tim Strayer present best practices for every aspect of VPN deployment, including tunneling, IPsec, authentication, public key infrastructure, and network/service management. Strayer and Yuan begin with a detailed overview of the fundamental concepts and architectures associated with enterprise VPNs, including site-to-site VPNs, remote access VPNs, and extranets. They compare all options for establishing VPN tunnels across the Internet, including PPTP, L2F, and L2TP. Next, they present in-depth coverage of implementing IPsec; establishing two-party or trusted third-party authentication; building a robust public key infrastructure; and managing access control. The book includes expert coverage of VPN gateway configuration, provisioning, and management; Windows and other VPN clients; and network/service management, including SLAs and network operations centers. Finally, the authors preview the future of VPNs, showing how they may be enhanced to provide greater quality of service and network intelligence. For all networking and IT professionals, security specialists, consultants, vendors, and service providers responsible for building or operating VPNs.
