Abstract
Objective. In decision making when comparing alternatives, it is often necessary to work with different values or estimates that are still important. One of the multicriteria analysis methods that can be applied in the model for determining the vulnerability of cloud computing areas is the ELECTRE I method. This paper presents an algorithm for determining the degree of vulnerability of cloud computing areas using the Electre I method. Method. The Electre I method allows one to evaluate the relative advantages and disadvantages of different cloud computing areas based on a set of criteria. Result. The algorithm presented in the paper includes steps for determining the weights of criteria, evaluating alternatives according to these criteria, and calculating the degree of vulnerability. This model will allow one to determine the area or areas that are most susceptible to the danger of breakdown or failure, and to remove dominated alternatives that do not pose a serious danger. Based on the identified preferences, one can make a decision on troubleshooting the selected areas of the cloud service. An experimental study was conducted on the basis of real data on the cloud computing system. Conclusion. The obtained results confirm the effectiveness of the proposed method and its ability to accurately determine the vulnerabilities of cloud computing areas. The results of this work may be useful for cloud system administrators and security professionals who are concerned about maintaining security and reliability in the cloud environment.
