Network frangibility correlation analysis method based on gradient attack hypotheses

Abstract

The invention relates to a network frangibility correlation analysis method based on gradient attack hypotheses, which comprises the network environment gradient and frangibility correlation analysis under a gradient network environment. The network environment gradient comprises network environment sub-network recognition and network environment gradient marking. The frangibility correlation analysis under the gradient network environment comprises a pointer initialization device, a transverse direction frangibility correlation analysis device with the same gradient, a longitudinal directionfrangibility correlation analysis device along the gradient direction, and a loop control device. Under the gradient attack hypotheses, facing a large-scale of complex target network, through the network scene gradient, the parallel partitioning of the network frangibility correlation analysis task is turned to be possible, and the foundation is established for the bottleneck of a large-scale application to break through the network frangibility analysis.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a network vulnerability correlation analysis method based on a gradient attack assumption. Background technique [0002] At present, with the rapid development of computer network technology, governments, enterprises, schools, individuals, etc. are connected to the Internet in different ways, and people's production and life are increasingly dependent on the Internet; The neglect of the Internet environment has led to increasingly prominent security issues in the Internet environment. In the Internet environment, there are always various attacks, and the technical means of attacks are becoming more and more sophisticated. Among them, targeted and planned multi-step aggregation attacks are becoming more and more common by taking advantage of the vulnerabilities in the network environment. This makes conventional protective measures impossible to detect. Under the threat...

Problems solved by technology

Under the assumption of monotonicity, since the attack has no directionality and the defense has no hierarchy, the vulnerability correlations between nodes in the network environment are intricate, and it is difficult to effectively divide tasks and solve them in parallel

[0012] Under the assumption of monotonicity, any two network nodes may be connected due to the relationship between the vulnerable points on the nodes. Any task division method must carefully handle the inextricable connections between the subtasks. , and the processing of these relationships may be more difficult than the solution of the problem itself, resulting in the more complex the problem is divided
