Research On The Risks Of Commercial Bank IT System Based On Resilience Theory

Financial industry has been the main foundation of Chinese economic development. Modern financial industry needs more support of knowledge and technology which is important to organization structure comparing with traditional financial industry. It’s obviously that IT(information technology) has become the platform of daily operation of commercial banks with the deeply integrating between bank’s business and IT. So, commercial bank depends on IT system more and more deeply. At the same time, there will be more risks form IT system. Then, it’s an urgent topic for commercial banks to manage IT system. Resilience management was come up with in1970, and has been applying in all kinds of industries. Therefore, on the basic of resilience theory, the thesis studies how to manage commercial bank’s IT system so that the loss of interruption will be reduced.Based on the study of characteristics of commercial bank IT system and resilience theory, we build Commercial Bank IT System Resilience model (CBISR) to provide basis for study commercial bank IT system resilience quantitatively. The research main contents are as following:Firstly, analyze the risks of commercial bank IT system on the basic of features analyzing. Besides, we redefine the resilience of commercial bank IT system with connotation of resilience management, and come up with a new resilience management method for commercial bank IT system.Secondly, integrating resilience theory and IT system risk management method, we build Commercial Bank IT System Resilience model with single interruption on basic of resilience triangle. We assume that commercial bank IT system suffers single interruption, robustness of IT system is relevant to degree of risk and invested capital prior, and the recovery rate has liner dependent with invested capital prior and emergency invest. The resilience triangle can represent the loss of IT system. Then, through analyzing of balance between loss and invest, we can find the best way of risk management. Thirdly, we assume that commercial bank IT system suffers risks repetitiously during recovery period. On the basic of fundamental model, we build patulous resilience model with multi-risks, so that it can deal with emergency management with frequent interruption.The study proposes a method of measuring commercial bank IT system resilience and supply a new risk management method, and some good advices are come up with to improve the resilience of IT system. The results obtained from the work have great theoretical and application value.
