Cryptography as an Instrument to Network Security
Network security is a complicated subject, historically only tackled by well-trained and experienced experts. However, as more and more people become "Wired", an increasing number of people need to understand the basics of security in a networked world. This paper was written with the basic computer user and information systems manager in mind, explaining the concepts needed to read through the hype in the marketplace and understand risks and how to deal with them. Some history of networking is included, as well as an introduction to TCP/IP and internetworking. The authors can consider risk management, network threats, firewalls, and more special-purpose secure networking devices.
