Service grid unit security protection strategy set recommendation method

The invention discloses a service grid unit security protection strategy set recommendation method, and relates to the technical field of data security. The method comprises the following steps of S1, clustering calculation of service grid units and security protection strategies; S2, calculating a membership matrix of the service grid unit; S3, calculating the membership degree of the security protection strategy; S4, generating a random forest; and S5, carrying out personalized online recommendation on the security protection strategy. According to the method, after the service resource grids and the security policies are clustered, the membership degree of each service grid unit or the security policies to each cluster is calculated, and the coupling conditions of various factors such as basic security attributes, time and space, behaviors and the like of the service grid units are fully considered when the membership degree is calculated, and training data of a supervised learning model is constructed acc
