e-Government services are becoming one of the most important and efficient means by which governments (G) interact with businesses (B) and citizens (C). This has brought not only tremendous opportunities but also serious security challenges. Critical information assets are exposed to current and emerging security risks and threats. In the course of this study, it was learnt that e-government services are heavily guided and benchmarked by e-Government maturity models (eGMMs). However, the models lack built-in security services, technical as well as non-technical; leading to lack of strategic objectives alignment between e-government services and security services. Information security has an important role in mitigating security risks and threats posed to e-government services. Security improves quality of the services offered. In light of the above, the goal of this research work is to propose a framework that would facilitate government organisations to effectively offer appropriate secure e-government services. To achieve this goal, an empirical investigation was conducted in Tanzania involving six government organizations. The investigations were inter-foiled by a sequence of structural compositions resulting in a proposition of a framework for securing e-government services which integrates IT security services into eGMMs. The research work was mainly guided by a design science research approach complemented in parts by systemic-holistic and socio-technical approaches. The thesis contributes to the empirical and theoretical body of knowledge within the computer and systems sciences on securing e-government structures. It encompasses a new approach to secure e-government services incorporating security services into eGMMs. Also, it enhances the awareness, need and importance of security services to be an integral part of eGMMs to different groups such as researched organizations, academia, practitioners, policy and decision makers, stakeholders, and the community. / <p>At the time of the doctoral defence the following paper was unpublished and had a status as follows: Paper nr. 6: In press</p>
