Cyber-Security Vulnerability Assessment Model for County Governments in Kenya
(International Journal of Science and Research, 2021-07-26) Kadima, Victor Chitechi; Omieno, Kelvin K.; Mbugua, Samuel Mungai
Computerization of county government daily activities enables faster and better services to their clients. The integration of Information and Communications Technology by the CG into their systems has led to new advancements in technology. The adoption of ICT into the Kenya’s County Governments has contributed to faster growth and output in better client service delivery. The benefits has also encouraged serious attacks to such systems causing risks due to easier penetration in the systems because of vulnerabilities. The attacks have costed county governments more resources and time in case of managing such risks. As a country, we need to ensure that all our systems are well safeguarded from attacks. This paper sought to address the above issue by developing a cyber-security vulnerability assessment model for County Governments in Kenya, The model can be applied as a better approach that will manage and reduce the attacks and risks. The Model was developed from a study that targeted a total population of 170 staff grouped as end users and ICT Experts working in county governments of Kakamega and Bungoma. The study adopted an exploratory research design. Stratified random sampling technique was used to group the counties while purposive sampling was used to identify the correspondence with the required information. A sample size of 98 end users and 37 ICT experts was obtained using Yamane’s formula. Questionnaires and interview schedules were used in data collection. The data was analyzed using SPSS where descriptive statistics of frequencies, charts, percentages and mean regression analysis were used and a null hypothesis was tested at 5% level of significance. Study results showed that there is a positive association between preparedness and awareness, support and funding, policies and regulations, and technology; hence influencing cyber-security. The developed model will be used as a guide to manage cyber security matters in Kenya’s County governments.
Integrating virtual worlds and virtual learning environments in schools in developing economies
(International Journal of Information and Communication Technology Research, 2012) Omieno, Kelvin K.; Wanyembi, Gregory; Mbuguah, Samuel Mungai
In recent years there has been significant growth in the use of 3D virtual worlds for e-learning and distance education. Virtual learning environment (VLE) has achieved an adequate level of development and supports teaching and learning in an educational context, offering the functionality to manage the presentation, administration and assessment of coursework. This paper’s main philosophical claims are that virtuality is itself a bonafide mode of reality and that VLEs must be understood as a possible platform for effective and quality teaching, learning and training. The paper investigates the suitability of virtual learning in Higher Education Institutions in Africa. It also explains virtual reality principle, describes the interactive educational environment, highlights the challenges HEIs face in the traditional mode of delivery and discusses educational benefits of implementing virtual reality. A number of demonstrative examples showing how virtual world/virtual learning environments can be integrated will be shown and the potential opportunities that exist in this area discussed. The paper then proposes a model for integrating virtual world tools with the existing learning environments.
The role of wireless technologies in taking education to rural villages in developing countries
(International Journal of Information and Communication Technology Research, 2011) Wabwoba, Franklin; Omieno, Kelvin K.; Simiyu, Carolyne N.; Sisungo, Zipporah W.
The development of wireless technologies has generated a considerable amount of excitement among practitioners and academics because it results in shifting the academic environment from traditional classroom restricted setting to open schools. The use of wireless technologies may be very important in provision of improved quality education for rural parts of the developing nations that lack a number of necessary facilities. The study conducted a survey among teachers in primary schools with specific focus on the challenges of the conventional classroom setting in rural Kenya. From the findings of the study a framework of utilization of wireless technologies is proposed to help overcome some of the challenges. The paper highlights the possibilities and potentials of the wireless technologies for various functions in the rural schools through the use of short message service (SMS), podcasting, video and mobile Web services among other approaches. The paper aims at providing a reference point for decision-makers, planners, teachers and administrators of developing nations to guide them to the world of wireless technologies.
