The Role of Cyber Security in Minimizing Crime Rate in Postwar Sierra Leone (Published)

There are numerous benefits one can get from using technological innovations ranging from comfort to minimal cost in telecommunications, health, aviation, commerce, energy, agriculture, intelligence, education via Internet and Internet of things (IoT). However, criminals have over the past decade accelerated highly sophisticated techniques to steal billions of sensitive and costly data either from private individuals, government or corporations costing billions of US dollars globally. Therefore, the research provides awareness as to how these Cybercrimes can be mitigated especially within the scope of Sierra Leone. It largely focuses on the establishment of the Cybercrime Unit at the Central Intelligence Department (CID), and the Office of the National Security (ONS), both units was created by an act of Parliament to secure and protect citizens against imminent cyber criminals within the confirmed of Sierra Leone. These agencies has been able to solve some of the crimes issues but yet still there exist unsolved problems. This is because of lack of many indigenous cyber security experts in the country. Also, the study indicated that the laws governing Cybercrimes are too weak to be able to tackle all the numerous issues relating the internet crime.

Modeling and Forecasting of Armed Robbery Cases in Nigeria using Auto Regressive Integrated Moving Average (ARIMA) Models. (Published)

We have utilized a twenty-nine year crime data in Nigeria pertaining to Armed Robbery, the study proposes crime modeling and forecasting using Autoregressive Integrated Moving Average Models, the best model were selected based on the minimum Akaike information criteria (AIC), Bayesian information criteria(BIC), and Hannan-Quinn criteria (HQC) values and was used to make forecast. Forecasted values suggest that Armed Robbery would slightly be on the increase

An Investigation on Crime Rate in Southeastern Nigeria (Published)

The modern world is everything but a safe place. This sad but indisputable fact has been proven to be true by several research. Crime rate is souring in this part of the continent and there exists many determinant to this anti-societal behavior amongst the people. In this paper, those variables that are crime prone in Southeastern Nigeria over a 10 year study period were determined using Principal Component Analysis (PCA); a Multivariate Statistical Technique that is use to reduce the dimensionality of a large number of interrelated crime variables while retaining as much of the information as possible. Data were collected on seven crime variables, from the data bank of National Bureau of Statistics (NBS). Moderate correlations exists between sizeable number of crimes, two principal components was extracted using the scree plot, explaining 86.4% of the total variation in the dataset. The highest and most committed crime in the study region are Armed Robbery, Murder and Grievous Harm and Wounding
