Cascade fault network vulnerability assessment and optimization system and method thereof

The invention discloses a cascade fault network vulnerability evaluation and optimization system and method, and belongs to the technical field of cascade faults, and the system comprises an information obtaining module which is used for obtaining the sum of the configuration information amount and the file information amount of a server, and obtaining the system data change when the server executes a task, an observation model is generated on the basis of the change of system data, and meanwhile, the variable quantity in the observation model is recorded and stored. According to the method, the measurement index is preset for the data security of the server system, and the service control authority and the service control type are collected after the server system is attacked and invaded, so that the calculation and storage states of each network and system after being attacked can be obtained; and the change of each node value in the attack process can be obtained under the conditions of normal occupancy ra
