Abstract
In electronic business environment, it is critical for an enterprise to assess information systems security (ISS) risks. In this paper, we propose a hybrid approach for ISS risk assessment in e-business. Given there is a great deal of uncertainty in the ISS risk assessment in e-business environment, in the hybrid approach, we combine the evidence theory with fuzzy sets to deal with the uncertain evidence found in the ISS risk assessment. The proposed approach provides a new way to define the basic belief assignment in fuzzy measure. Moreover, the approach also provides a method of testing the evidential consistency, which can reduce the uncertainty derived from the conflicts of evidence. Finally, the approach is further demonstrated and validated via a case study, in which sensitivity analysis is employed to validate the reliability of the proposed approach.
