Abstract: The measures deployed by the assessment results can reduce the negative impacts of the threats of informalion systems that we assess and predict in informatization development process. Proposed an model of infomation security threaten assessment based on AHP, which combining AHP with Fuzzy Comrehensive Evaluation, establishes threa assessment indicators,and plans to get the assessment result through the methods of assets identify, threats identify, threats analysis. The results of experiment verify the feasibility and validity of the model.

Key words: Threaten assessment, AHP, Assets identify, Threats identify
