Abstract

The invention discloses a system vulnerability discovery method and system based on a topology transfer relation. According to a relationship map of the number of nodes and a structure description system, simplification is conducted to form a vulnerability association map; according to a physical relation between the system nodes in the system, the transfer strength and probability of crash behaviors between the nodes are analyzed, some weak transfer relations are ignored, and a transfer relation matrix of the crash behaviors of the system is calculated; on the basis of the transfer relation matrix, key index vectors of the system are calculated; tightness indexes of an original system map are used for correcting the key indicator vectors of the system; on the basis of the key indicator vectors, hierarchical clustering and conclusion analysis are conducted on the system. The idea of combining the topology transfer relation, the coupling strength and a local structure is fully utilized,the depth and breadth of influence of key resources on the system can be fully reflected, and weak links of the system can be quickly found out.

Description

technical field

[0001] The invention relates to the fields of system engineering vulnerability discovery, system importance evaluation and the like, in particular to a system vulnerability discovery method and system based on topological transfer relations. Background technique

[0002] "System of Systems" refers to a large-scale system collection formed by the integration of multiple heterogeneous systems that can operate independently to accomplish specific goals. With the development of technology, the scale of the system is getting larger and larger, and more complex systems have emerged after integration on the scale of the system, which can cooperate to complete large-scale tasks that cannot be completed by individual systems. System Engineering (System of Systems Engineering) ) related theories have been widely used in aerospace, medical and health, environmental governance, weaponry and other fields. How to maximize the overall effectiveness of the system by optimizi...

Embodiment Construction

[0059] The following will take a typical guarantee system as an example to further describe in detail the system vulnerability discovery method based on the topology transitive relationship of the present invention. Guarantee work involves deployment, management, communication, maintenance, and material supply. Material supply may include various types of fuel, equipment, and supplies. Each component system performs its own duties to ensure the effective operation of the entire system. Each component system has a certain level of management relationship. Due to the existence of the support relationship, there are some intersecting loops in the system, forming a complex system relationship. A huge security system usually involves tens of thousands of nodes, and it is not easy to find the weak links in it.

[0060] like figure 1 and figure 2 As shown, the implementation steps of the system vulnerability discovery method based on the topology transitive relationship in this em...
