Embodiment Construction

[0028] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted here that the descriptions of these embodiments are used to help understand the present invention, but are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not constitute a conflict with each other.

[0029] As the first embodiment of the present invention, a method for mining vulnerabilities in industrial control systems based on fuzz testing is proposed, such as figure 1 As shown, including: first after the industrial control system runs stably, the detection device is connected to the industrial control system (step S1). In this embodiment, a detection device with a data transmission interface is used, such as a PC host with detection software; the detection device...

Abstract

The invention discloses a fuzz testing-based industrial control system vulnerability mining method and apparatus, and a vulnerability restoration method, and relates to the technical field of vulnerability detection. The vulnerability mining method comprises the steps of firstly connecting a detection apparatus to an industrial control system; obtaining data of the industrial control system by thedetection apparatus after the detection apparatus is connected to the industrial control system; generating a standard state form and standard running data by the detection apparatus; storing the standard state form and the standard running data after the standard state form and the standard running data are generated; and starting vulnerability detection by the detection apparatus wherein the vulnerability detection is performed through fuzz testing. By adopting the technical scheme, during delivery, the vulnerability detection is firstly performed, and original passive vulnerability detection and restoration become active vulnerability detection, so that the error probability of the industrial control system after delivery is reduced and the user experience is improved; and the fuzz testing is performed through the state form and the running data, so that the vulnerability discovery probability is higher and the accuracy is higher.

Description

technical field [0001] The invention relates to the technical field of loophole detection, in particular to a method, device and repair method for exploiting loopholes in industrial control systems based on fuzzy testing. Background technique [0002] The industrial control system, referred to as the industrial control system, is a system that controls machine tools or sensors through a computer or a bus. Because the industrial control system often needs to be installed on the industrial site, its overall sealing is better. However, due to the lower computing power requirements of industrial control, the version of the industrial control system at the factory is lower than that of the home system, which directly causes loopholes in the use of the industrial control system. Vulnerabilities can only be discovered when there is a problem in the system, that is, when a loophole occurs. There is no good method and device for actively exploiting loopholes in industrial control sys...
