Abstract

Existing information system risk assessment methods based on fuzzy language variables generally requires that the language variable itemsets generated by the standard parameter trapezoidal fuzzy numbers which are generated by experts in the field. The effectiveness of this approach then often depends on its ability to deal with different types of fuzzy numbers and changing linguistic variable itemsets when the expert cannot participate. This study presents a method for an n-fold reduction of the linguistic variables based on the triangular fuzzy numbers that is validated using four types of fuzzy numbers for language variables. The results show that the method automates the equivalent transformation of n-fold language variable items without expert intervention to improve information security risk assessment systems.

Key words
