The n-fold decrease of linguistic variables terms number method in information security risk assessment

The known information security assessment risk system (developed by authors) is based on processing methods of linguistic variables. Their foundation are reference parametric trapezoidal fuzzy numbers with different plurality of defining terms, the formation of which is associated with the involvement of experts in the relevant subject area. For more efficient use of such system it´s necessary to provide abilities: to handle different types of fuzzy numbers and to transform the amount of terms without experts in real-time mode. To solve this problem we propose the n-fold decrease method of linguistic variables, based on the fraction base extension. It gives an opportunity to formalize the process of transforming an equivalent number of linguistic variable terms on n-orders. This will improve appropriate information security assessment risk system by automating the process of function modification of the n-fold order decrease without the involvement of experts in the relevant subject area.
