Specifying When
Filtering Applies
Use the Time of Day setting to define time periods during which Internet
filtering is enabled. For example, in a school, it might be useful to enable
Internet filtering during normal school hours to protect students, but to
disable it after hours to give teachers complete access to the Internet.
Similar policies could be enabled to allow employees complete access to
the Internet after normal business hours.
Time of Day restrictions only apply to the Web Site Filter, Custom Sites,
and Keywords. Consent and Restrict Web Features, such as ActiveX, Java,
cookies and Web Proxy, are not affected.
Always Block
When selected, Internet Filtering is always active and Time of Day
limitations are not enforced. This is enabled by default.
Block Between
When selected, Internet Filtering is only active during the time interval
and days specified.
Enter the time period, in 24-hour format, and the start and end day of
the week during which you want to enforce Internet Filtering.
Filtering Web Sites
using a Custom List
This function allows you to block specific web sites, or restrict access to a
list of approved web sites. This is in addition to the Web Site Filter. and
overrides the more general Web Site Filter categories.
Click Filter, and then select the Custom List tab. A window similar to that
in Figure 30 displays.
