Configuration of Basic AnyConnect SSL VPN on Cisco ASA 

Cisco AnyConnect SSL VPN from Cisco Systems is a virtual private network (VPN) client. It enables secure remote access to an organization's internal network and resources.

To establish a secure, encrypted connection between the client device and the VPN server, the AnyConnect SSL VPN client employs the Secure Sockets Layer (SSL) protocol.

This enables users to safely access internal network resources from remote places over the internet, including as email, file servers, and other applications.

The AnyConnect SSL VPN client is available for a number of operating systems, including Windows, Mac OS X, and Linux, and it may be used in conjunction with Cisco routers or other VPN servers to provide remote access VPN services to businesses of all sizes.
