DESIGN AND IMPLEMENTATION OF A SECURITY AND JOB ACCOUNTING SYSTEM FOR A MICRO COMPUTER

ABSTRACT
The Design of a system security and Job Accounting system, aims at developing a proper and it logging and system security methods by using appropriate password administration and user identification techniques. This system stores different user information in a random file and performs and audit check on each new user identify. Authorization is granted when user, ID is found to be valid. In job Accounting, the system is design to computer customer changes for computer bureau services and the print out a billing list this would help in estimating throughput.
Proper system design technique adopted to achieve the design objective.
On the process of carrying out these functions a lot of sectors come into play, which indicates the major aims of the study.
This study of security and joy Accounting system, aims at developing a proper audit losing and security methods by using appropriate password administration and user identification techniques. In carrying out the design of a security and job accounting system for a microcomputer, a systematic design procedure was adopted.

The purpose of this study tends to find out the implication in which the system is design to compute customer changes for computer bureau service and to print out a billing list which would help in estimating throughout.
By showing the summary of research purpose, the study was systematically carried out and appropriate design measures adopted. This enabled the achievement of the design objective.

INTRODUCTION
1.0 BACKGROUND OF THE STUDY
Man out his initiatives, has some through series of stages inventing what are known as modern electronics (digital) computer.
Moreover, the use of microcomputers is now replacing the use of maintains and microcomputers in may fields of endeavors, especially business oriented and commercial applications. This can be attributed to the fact that they are easier to use and considerably cheaper than mini and mantrame computers. The development however, necessitates that there should be a form of protection for data held on these microcomputers against accidental or intentional destruction, modification or disclosure.
Specially, the microcomputer hard ware and software facilities should be protected against unauthorized use. An individual/owing of a computer system has the right to protect and monitor the use of the resources on his system. Without the security, of data on computer facilities, users would face a lot of problem both operation and social.

1.1 THE STATEMENT OF THE PROBLEM
There is this need for the resources of microcomputer system to be effectively, judiciously and efficiently utilized, not only that, it is also necessary to monitor who uses a particular system and how much such a user is to pay for services obtained, that is, there should be system security and proper job accounting.
The absence of security for computer system can result in a number of threats to the organization or to information user, such as, non availability of information to those who need them or alternatively the provision of information to those who should not have it. The design of an effective system security procedure would enable prevention, which is the task of trying to stop instances of misuses or failures from happening in the first place e.g ensure that unauthorized users are able to gain access an information system or protecting valuable data.

1.1.1 THE SUB PROBLEM
Absolute security cannot be achieved but must continuously be sought. The nullity is that as long as computer systems are utilized, there will continue to be the opportunity for accidental of deliberate failure. The primary goal of security system (prevention) is an ideal that simply cannot be achieved in all instances. Therefore, the best is to make some limited degree of prevention. Unfortunately, the method and degree that may be applied to minimize threats will themselves be constrained according to the perceived threats and costs of preventing the identified threats.

1.2 OBJECTIVE OF STUDY
(i) Design of a job accounting system that
