Discuss the problems associated with microcomputer security, and contrast the measures required to provide a secure environment with those of a mainframe computing environment.
What will be an ideal response?
The problems concern data security and physical security. Problems and precautions in dealing
with these are generally as for part two of the previous question. It is important that a contrast is
made with a mainframe environment. For example, in dealing with microcomputers, you are
dealing with individual machines and staff, possibly over a wide location. Much of the
responsibility rests with members of staff, consequently, all staff training is important. In the
mainframe environment it is possible to set up centralized controls (physical and logical).
Consequently, it should be an easier environment to control, with the responsibility residing in the
IT manager.
