A Data-driven Assessment Model for Information Systems Security Risk Management

Nan Feng, Xue Yu
Tianjin University, Tianjin, China

Abstract—In this paper, a data-driven assessment model for information systems security risk management is proposed based on the knowledge from observed cases and domain experts. In the model, genetic algorithm is applied to search the rules of security risk identification based on historical data. For identifying the causal relationships of risk factors and predict the occurrence probability of security risk, a Bayesian network (BN) is developed. Structure learning and parameter learning are utilized to integrate the database of observed cases with domain expert experience in the development of the BN. The significance of the work is that the model provides more objective and visible support for security risk assessment in the information systems.

Index Terms—Information systems, risk management, Bayesian networks, genetic algorithm.
