This unit looks at different ways of protecting a computer system. It considers how access can be limited to authorized users, and suggests ways of achieving this.

You are going to hear a discussion between a data processing manager and a computer consultant. The data processing manager is telling the computer consultant what security requirements his company needs for their computer equipment. The consultant has a checklist which shows different features suitable for a variety of systems. As you listen tick the appropriate column in the checklist. You need to decide whether the security feature is Necessary, Unnecessary, Permitted/Possible or Not Permitted/Impossible for the manager's computer system.
