Fault Tree Based Architectural Analysis for E-Business Systems
نویسندگان
چکیده
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.

Error assessment in man-machine systems using the CREAM method and human-in-the-loop fault tree analysis
Background and Objectives: Despite contribution to catastrophic accidents, human errors have been generally ignored in the design of human-machine (HM) systems and the determination of the level of automation (LOA). This paper aims to develop a method to estimate the level of automation in the early stage of the design phase considering both human and machine performance. Methods: A quantita...
