Firewall/Proxy Server

These two services can be on seperate servers or combined on one. With a school's local area network always connected to the Internet, a firewall is important for security. This protects against hackers from outside.

A proxy server can filter inappropriate web sites as well as accelerate the appropriate sites. When a user on the network hits a web site, the site is stored on the proxy server. The next time someone on campus tries to hit the same site, it checks the hard drive of the local server before going to the web.
