Site Rating

Introduction

Use GFI WebMonitor Site Rating feature together with the ISA Server web access blocking capabilities, to achieve automatic proactive blocking of sites which contain objectionable adult material such as pornographic images, candid scenes, offensive words and links to adult sites.

Figure 4 - Site Rating process flow

GFI WebMonitor can check for adult content in the URLs which users want to access. This is achieved by querying Yahoo! SafeSearchTM which is an online database that classifies and categorizes various sites on the Internet. When a user requests access to a site, GFI WebMonitor will query the Yahoo! SafeSearchTM database for the Content-Type held by that target URL. If the online web filter classifies the site as having adult content, GFI WebMonitor will add the target URL to the 'Adult' Destination Set on the ISA Server. If the ISA Server is configured to block access to the sites listed in the 'Adult' Destination/URL Set the user will be denied access to that site.

NOTE 1: GFI WebMonitor will retain the classification of the last 3000 sites accessed. Every time a request to a target site is made, GFI WebMonitor will check if the requested URL is listed in its internal cache. GFI WebMonitor will query the target online classification database only if the requested URL is not listed in its cache.

NOTE 2: GFI WebMonitor handles the adding of newly detected adult sites to the 'Adult' Destination/URL Set. ISA Server handles the blocking of the connections to the URLs listed in the 'Adult' Destination/URL Set.

NOTE 3: The Destination/URL Set 'Adult' is created on the ISA Server during the installation of GFI WebMonitor. To restrict user access to adult-rated sites, you must manually configure a rule on your ISA Server which blocks the connections to the URLs listed in the 'Adult' Destination/URL Set.

NOTE 4: You can change the name and category of the Adult Destination Set from the SiteJudge.js script. This script is located in the installation folder of GFI WebMonitor.
