AZAN-BASALLO, Yasser; MARTINEZ SANCHEZ, Natalia  e  ESTRADA SENTI, Vivian. The security risk of information in database managers based on trapezoidal fuzzy numbers. Rev cuba cienc informat [online]. 2017, vol.11, n.4, pp. 57-66. ISSN 2227-1899.

In this paper is proposed one solution for assessing the information security risk for database managers. It´s based on the qualitative risk of each parameter in the security checklist. To achieve this objective is proposing the use of trapezoidal fuzzy numbers based on area. A review of the literature of new similarity functions, which use the fuzzy numbers, is made to argue the selection of the chosen model to solve the objective in this work. A case study is presented to explain the operation of the proposed model and indicate its feasibility to handle the linguistic terms of the input premises and to achieve the determination of the information security risk assessment in a qualitative way. Also show the results obtained with the proposal through a tool developed that allowed to automate the proposed model.
