Abstract

Importance of security issues in computer networks has increased with the expansion of electronic data processing and transmission via the network. When operating on confidential information, it is important that the benefits of sharing and communication of a computer network to be supported by substantial security facilities. This is essential given that computer networks have come to be used including the development of banking, shopping or fees.
