Analysing usability and security issues in design and development of information systems

Recent technological advancements and the global economic challenges have meant that, individuals and businesses are constantly seeking new ways to exploit Information Systems (IS) and in manners that not only enhance user experiences and/or improve business processes and productivity, but also protect the individual‟s privacy and business assets for competitive advantage. Therefore, Information Systems need to be designed and developed to meet these challenges and/or other objectives. This thesis will delve primarily into the history of IS as a basis for establishing where the problem(s) lie or emanate from. It will focus on critically analysing existing Information Systems, and investigating the conflicting issues of usability and security, from an Information Systems Design and Development perspective by analysing various approaches. An in-depth review of literature and critical analysis of requirements necessary for the design and development of a usable and secure Information System will be carried out and will form the intellectual framework for this research. The premise therefore, is to look for a balanced approach or appropriate trade-off framework for designing usable-secure systems. The research will conclude with a discussion on how an envisaged conceptual framework or model can be developed based on certain influential factors, and how the framework can be experimentally evaluated, and to suggest areas for further improvement or future research.
