Network attack path generation method and device, equipment and storage medium

The invention discloses a network attack path generation method and device, equipment and a storage medium, and the method comprises the steps: obtaining the number of edges of each node in a network topology, and calculating the weight of each edge of the network topology according to the number of the edges; according to the vulnerability hazard score, the vulnerability number and the destructiveness of each node, the vulnerability attack probability of each node is calculated; based on a pre-obtained successful attack probability of historical vulnerabilities, constructing an initial Bayesian network between the vulnerabilities, and obtaining an initial joint probability of each attack behavior; according to the weight of each edge and the vulnerability attack probability faced by each node, optimizing the initial joint probability to obtain a predicted joint probability of each attack behavior; and updating the probability of the Bayesian network according to the dynamic vulnerability data, and further up
