SECURITY
Security is a very important issue because of a school environment with many young students that have lots of time to play on the network and attempt to destroy servers, take revenge, change grades, or even cause numerous problems on the intranet and the Internet.

For this reason, the students will be limited to the TCP/IP protocol. This protocol carries information of both source and destination. In this way, the source computer can be traced.

For security reasons, the administration will be using the IPX/SPX protocol developed by Novell. This protocol is an extremely reliable protocol and is a very secure protocol backed by an operating system that is also quite secure.

The students and the Instructors will only be using the TCP/IP protocol so in the Access control list, the 10.192.x.x and 10.224.x.x network which supports the students and instructor can be denied complete access to the IPX/SPX protocol with standard entries in the Access Control list. The standard mode ACL will reduce CPU cycles and keep router processing and latency to a minimum.

Proxy servers provide access to the Internet. In this way, decisions can be made for routing without burdening the router.

The proxy can also be configured to audit for tracing activity if necessary.

The firewall is accomplished through the wan router and the proxy. The internal IP number is a CLASS A reserved address 10.0.0.0 while the Internic assigned number is a class C address. Address translation must be used further isolating the intranet and protecting the integrity of the system.
