Overview If you’re one of the growing number of companies whose workers telecommute from home via virtual private networks (VPNs) and broadband Internet services, you know that these remote endpoints present a potential security risk. But you may not be aware that even conventional VPN firewalls, designed to protect telecommuters against Internet-born intrusions, are not enough to ensure the integrity of the VPN link. When securing remote endpoints, network administrators need to look beyond the employee’s computer alone and consider the company it keeps. Many telecommuters now share their broadband connections with other household members. These home networks offer a vulnerable “back door” that can expose your VPN and corporate network to a range of attacks--attacks that traditional VPN firewalls don’t always prevent.

This white paper explores the risks posed by home networking and shared broadband access, and explains why conventional telecommuter firewalls fail to provide complete protection. The paper then describes a new-generation VPN firewall, SonicWALL’s TELE3 TZX with an integrated 4-port switch that provides the first comprehensive, costeffective solution to the problem. The TELE3 TZX isolates an employee’s corporate computer from other household systems, shielding their VPN connection and the corporate network from vulnerable home networks. With the TELE3 TZX, network administrators can finally secure VPN endpoints easily and economically, even in heterogeneous home network environments.
