Virtual private networks have become an essential part of today's business networks,
as they provide a cost-effective means of assuring private internal and external
communications over the shared Internet infrastructure. Virtual Private
Networks: Technologies and Solutions is a comprehensive, practical guide
to VPNs. This book presents the various technology components, concrete solutions,
and best practices you need to deploy and manage a highly successful VPN.
Readers will find an overview of fundamental VPN concepts and
architectures, followed by an in-depth examination of advanced features and
functions such as tunneling, authentication, access control, VPN gateways, VPN
clients, and VPN network and service management. Specific topics covered include:
- IPsec, featuring the Authentication Header, Encapsulating Security Payload,
Internet Key
- Exchange, and implementation details
- PPTP, L2F, L2TP, and MPLS as VPN tunneling protocols
- Two-party and three-party authentication, including RADIUS and Kerberos
- Public key infrastructure (PKI) and its integration into VPN solutions
- Access control policies, mechanisms, and management, and their application
to VPNs
- VPN gateway functions, including site-to-site intranet, remote access,
and extranet
- Gateway configuration, provisioning, monitoring, and accounting
- Gateway interaction with firewalls and routers
- VPN client implementation issues, including interaction with operating
systems
- Client operation issues, including working with NAT, DNS, and link MTU
limits
- VPN management architectures and tunnel and security management
- Outsourcing and service provider environments
The book concludes with a forward look at the future of VPNs
that examines such issues as security and quality of service (QoS). VPN scenarios
throughout the book demonstrate how to put the described techniques and technologies
to work in a real-world Virtual Private Network.

Clearly explains VPN to those familiar to networks
The strength of this book is its clarity, which is achieved through topic selection, proper organization of topics, and different explanation of key concepts according to context. Coverage is wide. Meant for those who know networking and either want to learn about or implement VPNs. Btw the book is in English.

Very Good Book
One of the best books from a technology perspective - gives you details on what is out there with a suggestive look on what is coming in future. Do not buy this book if you are looking this as a hands-on book ; but if you are a network/security architect - this is a must. I find vendor coverage - but kind of limited - I'd have expected more details on primary VPN vendors, Cisco, Check Point & Nortel and the subscriber based VPN market that is just evolving.
