A network will never be absolutely secure since there is always a way to overcome the protection. However, data circulating on the network can be easily encrypted. Login procedure, password and in the future fingerprints or voice recognition can ensure authorized access.

Chapter 8 is an analysis of the 1995 and 2010 implementation of the ISUNet based on the expected user requirements for these eras. Each ISU department will have its own high speed fiber optic ring running at 100 to 1000 megabits per second. These DLANs will be interconnected by the CLAN using a similar ring network. The WAN will be connected to the central campus though standard ISDN telecommunication digital switches or by special routers This network hardware and software will support video conferencing, telepresence and all forms of packet switched data transfer. Chapter 8 also discusses the personnel required to develop, support and administrate ISUNet.
