School Filters: how the stuff works

This is the story from the guy, who worked as an admin at school.

Most large scale companies and well established school systems use a filter service that uses the filter definitions. At that school they use Lightspeed. Lightspeed installes a server that filters all traffic from the internet into the school's network. Every day Lightspeed downloads the sites addresses their customers have blocked by hand, process that definitions by their proprietary algorithms and serve out a new list of definitions. Additionally, Lightspeed spiders are also crawling the web and assigning categories based on content, keywords, and server owner, as well as other factors. Lightspeed (the service) also uploads the defintions to the local filtering server which are then joined to our local filter. Most proxy websites are categorized under proxy/security. That ones that the filter hasn't caught, admins get from the students by walking around and looking at the screens. :)
Even more, filtering servers can also filter web sites through keywords and redirects. If anyone try to search the term "proxy" the filter blocks that search query. When students type the myspace.com, the filter automatically redirect to yahoo.com. I suppose most enterprise-level filters act in the same way.

How Do Proxy Websites Protect Your Privacy?

Proxy websites become popular nowadays. They are great tools to make you invisible while browsing the web.
Proxy websites are also useful when accessing the Internet on public computers. Proxies help you to browse the Internet without being blocked or traced by software that restrict the use of the web.

Proxy websites will help to protect your computer by not giving your private information such as IP address away to third parties. Instead of using the one from the user, it will use the its own IP address to request the service from the websites you are browsing. You will also keep the privacy in your local computer since proxy website will hide all the websites addresses you have been browsing through the proxy. All you need is to enable url encryption feature. No one who might have access to your computer will know what sites you have visited. To increase security of your internet browsing, please use different proxy websites for each session.
