Features: In today's world where information technology plays a crucial role in social and economic development, both general and professional users have increasingly high demands for network services and their applications. In this market environment, a more cost-effective and flexible Virtual Private Network (VPN) has emerged. VPN technology is built upon the public network architecture of the Internet, replacing standard Wide Area Networks (WANs) between partners and achieving secure data transmission similar to that of a private network through certain technical means. As an integral part of network security, Virtual Private Networks play a significant role. Based on in-depth research and extensive reference to numerous similar works, this book systematically introduces the basic knowledge and framework structure of VPNs, analyzes VPN-related security issues in networks, and provides solutions to these problems, including tunneling technologies, encryption technologies, QoS technologies, and related products and vendors. This book is primarily aimed at individuals preparing for the National Informatization Security Education Certification (ISEC) exam, as well as network security administrators in enterprises and institutions in the telecommunications, power, finance, public security, and other sectors. It can also serve as a reference book for senior undergraduate and graduate students in network and communication-related fields studying network security courses.
