A Security Risk Analysis Method for Information System Based on Information Entropy

摘要

According to the problem of the uncertain information is difficult to quantify in information systems securityrisk analysis process, proposed an information system security risk analysis method based on information entropy. Thismethod use information entropy to measure the risk of information systems, introduce the information entropy theory, andget the value of the risk of various risk factors with the combination of qualitative analysis and quantitative calculation, toevaluate the risk factors of concern in the system and take appropriate control measures. The paper constructs an informationsystem security risk analysis model and through the case analysis verified the proposed method can be effectively appliedto information system security risk analysis.
