The phenomenon of over-reliance on subjective assignment is a challenging task in the information
security risk assessment process. This study deals with this problem. We have presented a group decisionmaking
information security risk assessment method by combining Analytic Hierarchy Process (AHP) with
Information entropy. When AHP is used to assess the security risk of information systems, the elements of the
Criteria level are the risk probability, impact and uncontrollability. The priorities of the Alternatives as risk
factors with respect to the Criteria level are determined by applying the group decision-making approach. And
the experts’ weights are obtained through information entropy. The experts’ judgments are aggregated into a
consensus matrix. The consensus matrix reduces the subjectivity of judgments due to the experts’ preferences.
Key words: Analytic hierarchy process, consensus matrix, entropy, group decision-making, risk assessment, risk factor,
