Cisco® SSL VPN solutions (formerly known as Cisco WebVPN solutions) give you a flexible and secure way to extend networking resources to virtually any remote user with access to the Internet and a web browser. Remote access based on SSL VPN delivers secure access to network resources by establishing an encrypted tunnel across the Internet using a broadband (cable or DSL) or ISP dialup connection.

SSL Remote Access VPNs provides you with a basic working knowledge of SSL virtual private networks on Cisco SSL VPN-capable devices. Design guidance is provided to assist you in implementing SSL VPN in existing network infrastructures. This includes examining existing hardware and software to determine whether they are SSL VPN capable, providing design recommendations, and guiding you on setting up the Cisco SSL VPN devices. Common deployment scenarios are covered to assist you in deploying an SSL VPN in your network.

SSL Remote Access VPNs gives you everything you need to know to understand, design, install, configure, and troubleshoot all the components that make up an effective, secure SSL VPN solution.
