Patent ID: 12013951

Abstract:
A cross-site scripting (XSS) risk analysis method based on a Bayesian network and a STRIDE model includes: constructing an XSS attack-related STRIDE threat model of a network information release system; obtaining a network structure of a Bayesian network-based XSS attack risk analysis model based on the STRIDE model; obtaining prior probabilities of all nodes in the network structure of the Bayesian network-based XSS attack risk analysis model based on expert experience and a node ranking algorithm; obtaining a training dataset through simulation by using a rejection sampling algorithm or a direct sampling method; performing network training on the network structure of the Bayesian network-based XSS attack risk analysis model by using the training dataset to obtain the Bayesian network-based XSS attack risk analysis model; and reasoning a Bayesian network to obtain a quantitative analysis result of an XSS attack risk of the network information release system.
