| dc.description.abstract | Banking industry have increased dependency upon technology solution that enables their financial products and services but the convergence of technology renders to increasingly vulnerable to malicious attacks. As such, the need to ensure information infrastructure protection of the banking industry is a must and hence designing security architecture ought to be seen as a good manner. Multi-tiered security architecture is a term which has different security technologies and measures to protect against different vectors of attacks. The main objective of the thesis is to investigate and design a multi-tiered security architecture towards information infrastructure protection. To achieve the main objective, it‟s imperative to identify factors affecting information infrastructure protection. Therefore, a security architecture consisting three main themes: communication network, associated software‟s and delivered services was used to identify current practice in information infrastructure protection of the bank. Design science research methodology was employed to approach the design and development of the architecture following Peffer et al. (2007) process model. The design and development of the architecture passed through several stages, initially factors affecting information infrastructure protection were identified using the quantitative, qualitative, observation and network traffic analysis tool, and then these were used as design inputs. There were multiple brainstorming sessions for the design enhancement as participative modeling was the overall approach for the architecture design. Given the difference in scope and magnitude of the challenges identified in the study, the proposed architecture approaches information infrastructure protection through continuous improvement. The architecture was finally evaluated in terms of component‟s completeness, comprehensiveness and fitness to the organization through an evaluation questionnaire and expert interview, accordingly, the developed architecture has capable to protect information infrastructure of the organization. | en_US |
