Abstract

The invention relates to a system for predicting industrial control network vulnerabilities based on N-gram, which is implemented by the following steps: S601, removing industrial Internet stop words in Sore based on an industrial Internet stop word bank, and segmenting the Sore at the positions of the industrial Internet stop words to generate corresponding text fragment sequences; step S602, performing preset N-gram word segmentation processing on each Frei, and performing combination and duplicate removal on segmented words of all the Frei of each Sret to obtain a corresponding segmented word vector FBe; step S603, combining and de-duplicating the segmented words in all the FBe to obtain a segmented word set FC, and determining the number of the segmented words of the FC as the dimension of one-hot coding; step S604, performing one-hot coding on the word segmentation vector FBe based on the dimension of one-hot coding, and obtaining an original feature parameter value of each Sret; and step S605, training based on the original characteristic parameter value of Sre to obtain an industrial control network vulnerability prediction model, and predicting the vulnerability outbreak probability of the industrial control network. According to the invention, the vulnerability outbreak probability of the industrial control network can be quickly and accurately predicted, and the safety of the industrial control network is improved.

Description

technical field

[0001] The invention relates to the field of computer technology, in particular to a system for predicting loopholes in industrial control networks based on N-grams. Background technique

[0002] With the accelerated integration of cloud computing, big data, artificial intelligence, Internet of Things and other new-generation information technologies and manufacturing technologies, industrial control systems have changed from closed and independent to open, from stand-alone to interconnected, and from automation to intelligence. While industrial enterprises have gained great momentum for development, a large number of security risks have also emerged, from the Stuxnet virus targeting the Iranian nuclear plant in 2010 to the Havex virus sweeping Europe in 2014, etc., targeting industrial control system networks (hereinafter referred to as industrial control networks) Attacks are becoming more and more serious, and industrial control systems are in urgent need ...
