| Abstract: | Based on SSE-CMM,the security risk factor of the information system(IS) is recognized.The method of fuzzy comprehensive judgment is applied to the risk assessment of the IS security.The weight of the risk factor is calculated by the entropy-weight coefficient method and the subjective influence of the experts judgment is reduced.Experimental result indicate that the proposed method is efficient and practical. |
