A New Risk Assessment Model for E-Government Network Security Based on Antibody Concentration

Risk assessment is one of the most important issues in the field of e-Government network security. Inspired by the principles of biological immune system, a new risk assessment model for e-Government network security, referred to as ACENS, is proposed in this paper. In ACENS, the artificial lymphocytes are used for assessing the risk of e-Government network security, and the lymphocytes´ concentration changes with the trend of the real attack intensity. Theoretical analysis and experimental results show that ACENS is valid, and it has the features of real time and self-adaptive. Thus, it provides a good solution to risk assessment for e-Government network security.
