A comparative analysis of mainframe and network computer security: From 1975 to present

This paper chronologically compares mainframe security to PC/Network security. Mainframe computer systems were originally designed to have a strong centrally administered security scheme. Access control and authorization can be controlled from one strategic location. Security was incorporated into the machines from the start. Personal computers were originally designed to have an independent feel away from the mainframe. These independent feeling PC's were then put into a network for ease of data sharing. The technology to make these networks better grew faster than security policies. Security was always an afterthought. It is concluded that mainframes have strong robust security systems and products, with over two decades of proven performance. While there are many products available, network security is considered weak in comparison to mainframes. There are many good network security products on the market but the industry lacks standards to make them all work together.
