Appendix A: Web Filtering Categories
Optinet has several distinct layers to identify and filter web sites depending upon the
settings you employ on the device. Among the most distinct layers are URL checks against
database entries, key-word searches, real-time analysis on web page context, digital
certificate scans, and full payload decryption on HTTPS/SSL traffic. These distinct layers
allow Optinet to quickly categorize well-known web sites while providing a more in-depth
identification for new, indistinct, and constantly changing Web sites.
If you would like to confirm the categorization of a web site, you can use the diagnostic tool
of /?webFilterCategory. To use this tool, go to any computer that is being filtered by
Optinet and open a web browser.
Enter the URL of the web site you want to confirm categorization, and append to it the
phrase /?webFilterCategory, i.e.,
http://www.google.com/?webFilterCategory
. This will post
the Web Filter Category Report and list the categorization of the web page and which
component (URL database, key-word search, or content analysis) categorized the site.
If you would like to re-categorize a web site, you can use the Custom Category Rules menu
(Admin -> Configuration -> Custom Category Rules) or submit the URL to
http://www.blackbox.com/category
.
The following table lists the available categories, together with the filtering level typically
applied to each. These categories are followed with a brief description of the type of
content contained by each and some web site examples.
