Fault Tree Based Architectural Analysis for E-Business Systems

Wang Chu and Yanli Feng

Full text: PDF


The increasing complexity of the e-business systems urges the improvement of existing methods of system analysis in order to reduce the likelihood that important threats remain unidentified. Such an improvement can be achieved by combining risk analysis methodologies with the architecture centric system design process. Existing methods are inherently deficient as far as vulnerability analysis for system architecture is concerned. This paper integrates Fault-Tree Analysis (FTA) technology and architecture centric system analysis method to analyze e-business system architecture. The analysis process sets focus on FTA driven scenarios generation and vulnerability analysis. The fault tree based architectural analysis approach is strongly architecture-centric. It can be used to discover component-level vulnerabilities. It is simple because the FTA diagram is intuitive and easy to be constructed. It provides an effective approach to e-business system architectural analysis.
