Information security evaluation of e-government systems

An information security assessment model based on the systems security engineering capability maturity model (SSE-CMM) is proposed according to characteristics and security requirements of e-government systems. Fuzzy comprehensive judgment is also applied to mitigate the uncertainty of threats and weaknesses in e-government systems. To overcome the subjectivity in fuzzy judgment, assessment factors are calculated objectively by the method of entropy weight coefficient. Finally, the study of a case shows the security degree of an e-government network system can be conveniently found out with this method, while efficiently decreasing the computing complexity and influence form human factors.
