Abstract: According to the problem of redundant attributes for indicator system of information security based on electronic archive, an attributes detection method based on correlation analysis is presented. The proposed algorithm exploits the principles of the quantified indicators properties, and the correlation between the indicators properties according to mean and standard deviation of indicators properties is measured; aiming at the problem of the low accuracy on risk assessment of information security , multi-factor hierarchical fuzzy comprehensive evaluation model based on AHP and fuzzy mathematics is proposed. The practical application on a certain information system proves that it can assess the system directly and effectively, and the assessment result is to actual with higher degree ,and it can provide reliable basis for decision making of risk about information security．
