This topic deals with the net difference in the security posture resulting from the proliferation of the business world by microcomputers and computer networks. The following are the premises that will be discussed: A. Large 4th generation computer systems, while not fully secured, were designed with some level of controls, auditibility and recovery; B. Microcomputer design and operational characteristics have created a multitude of new security problems while resolving a variety of old security problems; C. Networks, while compounding some security problems, also mitigated many microcomputers related data base system controls and auditing problems.
