Introducing the

Web Site Filter

The 3Com SuperStack 3 Web Site Filter (3C16111) provides the

SuperStack 3 Firewall with enhanced Internet filtering capabilities. It can

control access from the LAN to thousands of Web sites that might be

deemed inappropriate for business use. Twelve selectable Web site

categories are provided so Internet access can be tailored to the needs of

the organization. Just like the Custom List and filtering by Keywords (see

Chapter 8), access to these sites can be enabled or disabled.

The 3Com Web Site Filter is provided as a 12-month subscription, and

can be automatically updated weekly to ensure that the filter keeps pace

with the ever-changing Internet.

The Firewall comes with a one-month subscription free of charge.

The 3Com Web Site Filter uses the CyberNOT list, which is licensed from

The Learning Company. This list is developed and maintained by The

Learning Company's Cyber Patrol unit.

The sites on the CyberNOT List are reviewed by a team of Internet

professionals, including parents and teachers. They use a set of criteria

that categorizes Internet sites and resources according to the level of

possibly objectionable content.
