The diversity of Internet of Things (IoT) systems can be viewed from two points of view, one that consists of providing the necessary applications and another that can lead to a large number of security threats and attacks. The analysis of the influence between different IoT security requirements (IoT-SR) as well as the determination of the importance of each security requirement play a vital role in the issue of the effective evaluation of an IoT system. The diverse nature, importance, evaluation and influence of multiple IoT-SR are the main issues that make this problem a multi-criteria problem. Considering the qualitative nature of IoT-SR and the advantages of fuzzy sets in efficiently dealing with uncertainty, fuzzy subjective weighting methods can be used to address the problem. The paper proposes a Multi-Criteria Weighting Approach (MCWA) based on the Fuzzy DEMATEL method in combination with two weighting methods, aiming to analyze cause-and-effect relationships for a set of criteria and to calculate the criteria weights. An application of MCWA for IoT-SR is realized. The obtained results can open new ways for system security specialists to focus on security requirements determined to be of increased importance.
