CHAPTER

ONE





INTRODUCTION





1.1  

BACKGROUND

OF STUDY





Information system occupies a vital and

unique position in any organization by virtue of the data and information,

which it contains. Security of information is of great importance to any given

organization this makes the information reliable since information stored can

be referenced whenever necessary access by unauthorized persons.





This project analysis the activities and

importance of securing information in any organizations and to see that the

information is accurately maintained to help the management in decision making

and control of the diverse activities of the organization.





The Nigeria police force is responsible for

security of live and property and as a result keeps record of vital information

given to them by any informant so as to enable them arrest activities or scenes

unpleasant to people residing in a particular district.





Therefore, for effective administration and

management, the provision of computer based information security for every

source station is certainly inevitable, since it will take care of all the

problems and inadequacies of the manual system.





 





 





1.2  

STATEMENT

OF THE PROBLEM





Inspite of the level of computation of

various organizations, this particular organization on discussion is still at

the grass root level. It requires a certain degree of protection especially of

vital equipments, properties and information and this cannot be realized

through the current system of operation, which is the manual system.





 





1.3  

PURPOSE

OF THE STUDY





The purpose of this study is to provide a

computer based, on line and interactive package that will accurately and

efficiently record all data and information about staff, informers, witnesses

and accused persons.





It will also eradicate the numerous problems

associated with the manual technique of securing information in order to

facilitate the transfer and retrieval of information between the various

departments of the organization,





 





 





1.4  

AIMS

AND OBJECTIVES





Having studied the activities of the police

station some benefits could be derived from the computerization of information

system and this includes:





1.     

Higher

security efficiency of information





2.     

Quicker

access to individual data





3.     

Faster

treatment of information security oriented cases.





4.     

Provision

of output information in a readily comprehensible form to those persons

involved in the activities of the organization. Provision of communication channels.

To compass formal and informal component.





To provide storage facilities

for data not immediately required or that may be required to be used more than

once.





 





1.5  

THE

SCOPE OF THE STUDY





The scope of this study is to eradicate the

numerous problems associated with the manual technique of securing information

in order to facilitate the retrieval of information.





 





1.6  

LIMITATIONS





A lot of militating constraints were

encountered during the course of this write up. They are:-





Inaccessibility to some documents, which

arose due to security, imposed on some of the organization documents by the

management. It was not also possible to make an in-dept study of these

documents, which would have helped in the development of the project work..





Time was a major limitation to this write up,

there wasn’t enough time to study the details of the various field of the

information department of the organization unavailability of textbook needed

for this write – up was not found in the institution library.





 





1.7  

ASSUMPTIONS





For easy implementation of this study some

assumption were made.





It is assumed that the software to be

designed for the study will help police stations in the effective storage of

vital information.





Finally, it is also assumed that by

computerizing this organization, information security has been implemented to

handle their day to day cases in a better and more organized manner.
