Comparative analysis of methods of assessing the protection of wireless fire alarm systems
A comparative analysis of methods for assessing the security of wireless fire alarm systems based
on the analysis of numerical samples representing the assessment of security, using the apparatus of
mathematical statistics. Using a variety of nonparametric tests (criterion of signs, the Wilcoxon test)
in the program Statistica the average and confidence intervals of sample means (graphic diagram
«box and whiskers») that are close enough to each other. The average and confidence intervals that
show the security assessment based on fuzzy logic, is slightly higher than the average and confidence
intervals that show the security assessment based on the matrix of fuzzy rules. This is interpreted as
a higher quantitative evaluation of security based on fuzzy logic in comparison with a quantitative
evaluation of security based on the matrix of fuzzy rules and, consequently, more accurate identification
protection. Also the proposed approach the comparative analysis of quantitative indicators potentially
can be extended to a wider class of problems of information security, such as comparative
analysis of various «related» methods of assessment.
