Abstract

The invention discloses an incidence matrix-based object-oriented network attack modeling method and device, and the method comprises the steps: describing a communication information network structure and a network attack path through employing an incidence matrix method; and describing the modes and processes of network attacks with an object-oriented method. According to the method, the influence of attack behaviors on a single node or link can be analyzed, and potential vulnerabilities of the single node or link can be found; the method and the process of the network attack and the attackpath in the network can be visually reflected, the vulnerability of the system can be conveniently analyzed by the network security personnel, the attack source and the attack path can be found out, and the network security analysis is promoted to be expanded from a local area network or a smaller network to the whole network, so that the management capability of the network is improved.

Description

technical field [0001] The invention belongs to the technical field of network security, and more precisely, the invention relates to an object-oriented network attack modeling method and device based on an association matrix. Background technique [0002] With the construction of the ubiquitous power Internet of Things, the structure of the power grid and communication information network will become increasingly complex, and the coupling will be closer, which brings a new threat to the safe and stable operation of the power system—the security threat of the information communication system. Hackers' attacks on information and communication systems can directly or indirectly affect the measurement and control of the power system, and further affect the safe and stable operation of the power system, and even lead to large-scale power outages. In the face of endless network attack cases, it is necessary to model the attack process from the overall situation of the network, pr...
