Here is the session description from the one hour session description page of the NYSCATE wiki:
How can you detect and block anonymizing proxies to stop students from accessing content which can create security risks to your network? Sophos security expert, Chris Ridgeway, will discuss risks posed by Web 2.0., how anonymizing proxies compound that threat and best practices to thwart anonymizing proxies in your network.
To me, the title represents what can be so wrong with security and the companies that provide them. Granted, they prey on the fear that some parents and administrators have. They aren't as concerned with providing effective instruction as they are creating an impenetrable bubble isolating students from the rest of the world. If you had engaging instruction and a relevant curriculum, you would have less discipline issues. It's as simple as that.
