Firewall

Introduction

When you connect your private network to the Internet, you are physically connecting your
network to well over 50,000 unknown networks and all of their users. While such
connections open the door to many useful applications and provide great opportunities for
information sharing, most private networks contain some information that should not be
shared with outside users on the Internet. In addition, not all Internet users are involved in
lawful activities. These two statements foreshadow the key questions behind most security issues on the Internet:

How do you protect confidential information from those who do not explicitly need to
access it?

How do you protect your network and its resources from malicious users and accidents
that originate outside of your network?

Firewalls  provide the first line of defense against Internet security threats for your business. This element provides the means to control access to critical network applications, data, and services so that only legitimate users and information can pass through the network

Virtual Private Network (VPN)
Using the SonicWALL VPN Client 8.0 application, mobile users can securely connect to their office network's SonicWALL VPN gateway and enjoy the benefits of broadband performance and the privacy of a Virtual Private Network (VPN). The SonicWALL VPN Client software is ideal for mobile users needing secure access to mission-critical network resources, but for mobility reasons, are unable to utilize a SonicWALL VPN appliance-based solution.

Implemented in collaboration with VeriSign, the leading provider of trusted infrastructure services, SonicWALL Authentication Service is an affordable, easy to administer, end-to- end digital certificate solution for your organization. Digital certificates and public key infrastructure (PKI) are widely accepted as the best solution for establishing user identities with absolute confidence.

Using an Web-based interface, this service generates detailed reports of security weaknesses and provides administrators with in-depth guidance on how to address the risks.
