| Popis: | In this article, the authors evaluate the quantitative gain in the precision of the security assessment methodology based on the fuzzy logic, presented in previous works of the authors, in comparison with the probabilistic stealth assessment by the example of wireless fire alarm systems. For this purpose, on the basis of probabilistic stealth assessment and analysis of the known literature, stealth assessment of known technologies of protection of the radio channel of fire alarm systems was carried out. Energy and structural stealth were used as the main probabilistic stealth assessment. To obtain an estimate of the quantitative gain, the "affinity" of the concepts of "stealth of communication" and "security of communication" is precisely shown. As a result of the calculations based on the average error index of the MAPE approximation, it was found that the quantitative security estimates obtained by the method of security assessment based on fuzzy logic are 25% more accurate than the quantitative estimates obtained by the probability stealth assessment. For the reliability of the calculations, the R2 determination coefficient, the mean and confidence intervals of the sample means (graphical chart "box and whiskers"), which confirmed the obtained calculations, were additionally calculated. Due to the calculated quantitative gain in accuracy by assessing the security based on fuzzy logic, it is possible to calculate a more accurate quantitative assessment of the security of wireless fire alarm systems, as well as to build their ranked list by the security criterion. The proposed approach, after appropriate adaptation, can be used to quantify the security of other communication channels of fire alarm systems, for example, for wired communication channels, as well as for a wide class of wireless security systems. |
