Web site technologies such as cookies and Java and
ActiveX applets give enhancements to web pages, but
hackers may use the technologies to steal or damage data.
The Internet Firewall can block these potentially damaging
applications from being downloaded from the Internet, or
allow them only from trusted sites. See
page 69
You can also use the optional OfficeConnect Web Site Filter
to extend these filtering capabilities of your Internet
Firewall. It provides a list of Web site categories that might
be considered inappropriate for business use. The Web Site
Filter updates the Internet Firewall with the latest URLs
matching the selected categories. You can block access to
these sites or log them. The Internet Firewall is supplied
with a one-month free subscription to the Web Site Filter.
You can then purchase a 12-month subscription.
