Secure Remote Access Technical Solution Guide v1.0

______________________________________________________________________________________________________

1. Overview

Today’s enterprise network must support a growing number of mobile workers who require

access to a broad range of information and applications. These workers include full-time

teleworkers who use remote access as the primary connection to the network and services.

There is also a growing number of occasional teleworkers. Another key user category is the road

warrior, who improves productivity by engaging customers and business partners out of the office

but must stay connected. As organizations recognize the benefits of IP Telephony and multimedia

solutions, including intelligent call routing, network presence, application integration, and network

convergence, they demand that these benefits be available beyond the traditional boundaries of

the enterprise network. This Technical Solution Guide provides a prescription for meeting this

requirement while providing the network and information security that must accompany such a

solution.

This guide provides a list of best practices for Secure Remote Access that reduce security

exposure and lower cost of operation. It provides information about solution design, deployment,

and network integration to maximize the benefits to your organization.
