    Factors Affecting Information Systems Security Investment in Selected Public Organizations in Ethiopia
    (Addis Ababa University, 2023-06) Eden Zewdie; Lemma Lessa (PhD)
    Ethiopian public institutions are investing in various IT infrastructure and systems to improve the effectiveness and efficiency of their operations. Organizations are highly dependent on network connection and information systems which make them to become hot point of cyber-security. With respect to this, the government of Ethiopia adopts a digitization strategy that strength security capacity as a key element. However, most Organizations have hesitated to make security investments due to several reasons. Most organizations do not consider how cyber-attacks affect the costs and benefits, which results in underinvestment in cyber-security. Due to the dearth of information determining the benefit on information security investment (ROSI) is always challenging. Decision-makers are frequently confused by the abundance of competing solutions and unsure of whether their investments in security are appropriate or even effective. The goal of this study is to identify the factors that affect investment in information security based on TOE framework. In addition, the study determines the significance of those factors that affect information system security investment and provide suggestion on how information system security could be guided. Identifying the factors that influence security investment decisions will assist decision-makers to drive better cyber-security investment decision-making in a proper manner. The study used a quantitative research method using questionnaires as a data collection tool. A total of 105 questionnaire sets were distributed, and 86 were returned, which accounts for 81.9% of the total response rate. Descriptive and explanatory analyses were used to examine the data. The result revealed that among organizational factors: management support, economy, awareness, decision support process, risk assessment, future Growth, and organization culture have significant impact on information security investment. Similarly, environmental factors, namely; legal and regulatory framework, have an impact on security investment. Based on the results, information system security investment could be guided by the support and commitment of management. Raising the information system security awareness among management and key decision makers can increase investment in information system security. The greater awareness and support on security among the decision makers, the greater the security investment. Furthermore, Organizations must take risk assessment; create security controls, policies, and frameworks in order to maintain their spending in information security.

    Maturity as a Critical Sustainability Factor for E-Government: Towards A Conceptual Framework
    (Addis Ababa University, 2022-06) Hiwot Feleke; Lemma Lessa (PhD)
    Extant literature reveals that many e-government initiatives fail, especially in developing countries. Despite the alanning failure rate of e-government initiatives, the governments of developing countries are allocating a huge budget out of their limited resources to support and improve e-government services.Prior research suggested that maturity is a prerequisite for egovernment sustainability, but the relationship between e-government maturity and sustainability has not been investigated. Hence, this research is aimed at developing a conceptual framework that maps e-government maturity to a sustainable e-government service. Qualitative case study was employed in selected government organizations in Ethiopia that provide e-service through the e-government portal of Ethiopia. The detenninants of e-government maturity and sustainability were derived from extant literature and the relationship between them were conceptualized. The conceptual framework was evaluated through document analysis and interview with experts. A six-step qualitative data analysis framework by Kiger and Varpio (2020) has been used to identify, analyze, organize, describe, and report patterns within the collected data. The study results show that availability of an ICT department with an independent annual budget for the e-government development, human resource capability/ human and intellectual capability, staff retention, manager's commitment to prioritize e-government projects, degree and frequency of customer contacts, customer satisfaction, ICT infrastructure development, integration, Website age, legal and political strategies, institutional instability, organizational e-government operational plan, political environment and e-payments were identified to be the detenninants of egovernment maturity. These detenninants are found as the key factors that affect e-govemment service maturity. Some of the detenninants identified from the literature review were excluded after the case study investigation and some other detenninants are newly identified. The study contributes to e-govemment literature by providing a better understanding on the detenninants of e-government service maturity and sustainability. Identifying the detenninants of maturity and sustainability and exploring the link between the two constructs improve our understanding of sustainable e-government services. The outcome of the research could also be of value for practitioners as a quality tool to assess the maturity and sustainability of e-govemment initiatives. keywords: Maturity, Sustainability, E-government maturity, E-government sustainaoility, Egovernment Success
