Computer Network Security

The computer network security is a key issue to promote the development of trade in all areas. One word ‘security’ covers many different aspects, both technical, organizational and legal. Latitude users against security problems is often irrational, which does not help to simplify the discussion. The safety of paying by credit card over the Internet is part of controversial topics. In 1996 our experimental platform Infoway, we asked our 10,000 users to pay a participation fee for access. All means of payment were available on the server from the secure online credit card, send the card number by fax or check. Contrary to popular belief, approximately 60% of users chose the secure online payment, 30% and 10% check preferred to send the credit card number by fax which even provided a PIN! The perception of safety is an important element to consider in developing these systems.

From a technical perspective, safety covers both access to information on workstations, servers and network data transport. In this short paper, we focus on the problems of information security in trade through public or private networks. Internet, the network of networks, is a tool that allows all computers regardless of their type to communicate with each other. Technology (TCP / IP) has simplified the creation of networks, thus reducing the cost of telecommunications. However, the security features are not addressed by this protocol.
