However experimental study associated to...

Security incidents affecting information systems in cyberspace keep on rising. Researchers have raised interest in finding out how to manage security incidents. Various solutions proposed do not effectively address the problematic situation of security incidents. The study proposes a human sensor web Crowd sourcing platform for reporting, searching...

This paper presents an innovative Soft Design Science Methodology for improving information systems security using multi-layered security approach. The study applied Soft Design Science Methodology to address the problematic situation on how information systems security can be improved. In addition, Soft Design Science Methodology was compounded wi...

The trend of organizations offering services through integrated applications using web- and mobile- based information systems has raised security concerns on how to ensure security goals are attained. The foundation of many systems’ security problems is the lack of integrating secure aspects throughout the processes of architecture design of inform...

The number of security incidents exploiting security holes in the web applications is increasing. One of the recently identified vulnerability in the web applications is the Heartbleed bug. The Heartbleed bug is a weakness found in OpenSSL, open source cryptographic software. In this study, both quantitative and qualitative research methodologies w...

The study was undertaken using a mixed research (quantitative and qualitative) methods. The research findings reveals that 12.8 % of users are victims of cybercrimes due to visiting...

Purpose The purpose of this paper is to analyse the effect of critical success factors (CSFs) on information technology (IT) governance performance in public sector organizations in a developing country such as Tanzania. Design/methodology/approach Based on a previous study and a further literature review, a research model was developed for analys...

Today in many organizations in the public sector, the use of IT has become crucial in sustaining and extending the organizations' strategies and objectives. Such use of technology has caused a critical dependency on IT thus a call for specific focus on IT governance. Despite increased practice of IT governance in these organizations, little academi...

Today in many organisations in the public sector, the use of IT has become pervasive in every facet of the organisations' endeavours in supporting and evolving public service delivery. This pervasive use of technology has caused a critical dependency on IT, which in this environment involves a complex mix of political, organisational, technical and...

Today in many organizations in the public sector, the use of IT has become crucial in sustaining and extending the organizations' strategies and objectives. This pervasive use of technology has caused a critical dependency on IT that calls for specific focus on the IT Governance. This paper discusses the current state of IT Governance practices in...

The implementation of information technology (IT) is always associated with a series of complex organizational change issues. In developing countries, these issues are even more complex because the IT infrastructure, technology and governance are still poorer and information systems development and associated resources are less established. Therefo...

The implementation of Information Technology (IT) is always associated with organisational change issues and in developing countries this is even more complex due to poorer and less established IT resources and governance. Therefore, our paper has focused to analyse the management of IT-enabled change in a public organisation in Tanzania by using W...
