Risk Evaluation Model on Enterprises’ Complex Information System: A Study Based on the BP Neural Network

As modern enterprises’ dependence on complex information system is growing, higher risks of using these information systems are thus incurred. This paper firstly made an overview of both the importance of complex information systems in enterprises and the universality of risks. Then proposed and analyzed are eight types of risks of complex information systems in enterprises: infrastructure, systemic projects, system application, information asset, business continuity, information system strategy, information system supplier and outsourcer, external risks of information systems. Finally, these eight risks are introduced to construct a risk evaluation model on the enterprises’ complex information system based on the BP neural network.
