Design And Implementation Of A Computerized Security Information System
(A Case Study Of Nigeria Police Force Enugu State)
A Computerized Security Information System (CSIS) is a comprehensive and dynamic platform designed to safeguard digital assets and sensitive information within an organization. It serves as a centralized hub for monitoring, analyzing, and responding to security threats and breaches across various layers of the IT infrastructure. By integrating advanced technologies such as machine learning, encryption, and intrusion detection, Computerized Security Information System empowers organizations to proactively identify vulnerabilities, detect anomalous activities, and mitigate risks in real-time. This system encompasses a range of functionalities including access control, threat intelligence integration, incident management, and compliance reporting, ensuring continuous protection against evolving cyber threats. With its robust features and adaptive capabilities, Computerized Security Information System plays a fundamental role in fortifying the cyber defenses of modern enterprises, enhancing resilience, and fostering a proactive security posture.
Security of life and property is an essential need of an individual as well as a generate body. This calls for the need for a well-organized information security system.
Before the advent of computers, there was no security of vital information’s, files where pulled out from cabinets from sections, which might result to misplacement of individual files, and documents as a result this project was implemented.
This project emphasis on information which is produced in a way understandable by man and the need to store this information so that need to store this information so that it can be referenced when necessary, it also describes how all these could be done electronically. It shows how information could be stored, modified and recalled instantly and accurately through computerization with out access by authorized persons.

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.
