The concept of triangular fuzzy number is introduced into the game model to solve the problem of cannot making accurate judgments on both offense and defense payoffs in game analysis. The payoffs
which are difficult to be described with accurate numbers
are expressed with triangular fuzzy numbers
and the game algorithm based on triangular fuzzy matrix is thus proposed. The complexity analysis verifies the time complexity to meet the requirements of network security assessment. The strategy based on the algorithm can ensure the minimum income of attacker to approach to 14.44; and for the defense system
the best defense strategy that greatly enhances the host system security is to adopt Install Patches. Compared with the traditional security assessments following game theory
introducing the concept of the triangular fuzzy number facilitates suiting the applications and improving the accuracy and validity of assessments.
