We use Dans Guardian and Squid. It does a fairly good job with most things, but any content filter is always "out of date" there are just to many web sites out there to keep up. We also monitor our computer connections to see where our most "abused" computers are surfing. By doing that we catch most of the new sites that have not made it into the filter yet. We also can monitor the user names of the surfers so we can shut down internet access to abusers that way. -----Original Message----- From: School Information Technology Discussion [mailto:[log in to unmask]] On Behalf Of Isham, David Sent: Friday, December 08, 2006 7:59 AM To: [log in to unmask] Subject: Re: use of proxy websites for anonymous surfing At GISU we use iprism. Proxy blocking seems to be what it mostly is blocking these days. I have gotten thru using a proxy in testing, but they usually get blocked soon. No way could you keep up with it yourself. Iprism costs money. I have heard "Dan's Guardian" is free, but don't know how well it works.

In response we are doing a schoolwide education piece, as well as upping the consequences to students for this particular infraction. We also have added several of the proxy website URLs to the custom blocked list, but don't for a moment think we'd be able to determine/keep up with them all. (btw, we use Sonicwall for content filtering). Is this the extent of what can be done to address this problem or are there other options that we've missed here at the school?
