Content Advisor
Microsoft Windows XP Home Edition
Security Implementation
Version 1.4b Option 1
The Content Advisor is a feature that will block web pages from being displayed
based on settings you setup. The users can still access the pages if they enter
the Supervisor password.
Internet Explorer uses a rating system to block sites. The rating system is
known as RSACi (Recreational Software Advisory Councils internet)

36 . There is
another rating system that you should consider downloading. The Internet
Content Rating Association (ICRA) produces this system 37 . To configure Content
Advisor you need to first download the ratings file for the ICRA. The ratings file
and other information on how to install and set it up are located at
http://www.icra.org/_en/faq/contentadvisor/. Once you have installed the ratings
file you can now setup your content filter. The ICRA rating file gives you a lot
more categories to filter than the RSCAi (4 categories). For each category there
is a number associated. This number indicates the explicit or intense rating. The
number range from 0 - 4 and the higher the number the more explicit or intense
the content.
You need to select the categories you want to filter and then set the limit for
them. A description of the current setting will appear under the slider as you
move it so that you can choose the appropriate setting. This step must be
performed for each category that you want to implement. Once you have made
all your settings you need to click OK. You will be prompted to type in a
Supervisor password. This password will be used to override the filter if you wish
to view a web site that has been disabled.
Not all sites are rated. For these types of sites you will get a dialog box to
instruct Internet Explorer on what to do. You have three options for the site. You
can always allow the web site to be viewed, always allow this web page to
be viewed, or you can allow viewing only this time. Whatever option you
select you will be required to type in the Supervisor password. If you don’t want
to protect your computer that you way you can set it so that all users can see
sites that have no rating. To do this you need to open Internet Options and go to
the Content Tab. There is a Settings button on this page. Click the Settings
button. There should be a General Tab in this box. On that page there is the
setting Users can see sites with no ratings.
