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.
