Research on Automatic Vulnerability Mining Model Based on Knowledge Graph

Abstract

In the information extraction, information sources can be screened according to the characteristics of the target network at the present stage, and the knowledge graph generated thereby can play a role in assisting the security analysis of the general network or power grid control network, mobile Internet and other special networks. In the method proposed in this paper, knowledge reasoning is mainly based on the attack conditions and attack methods to reason about the success rate and return of the attack. Through the obtained quality information, map construction information extraction and reasoning are performed to realize the correlation analysis of the information, and the information processing results are stored in the graphic structure. When analyzing the alerts generated by IDS, it is necessary to solve the multi-source alarm format generated by various devices produced by different suppliers. The attack diagram constructs the attack mode to guide the defense side to take targeted defense measures, and the attack success rate is used to judge the defense priority of all network nodes. After completing the construction of the graph, the attack graph is generated for the specific network environment under the guidance of the knowledge graph. In the process of attack graph generation, attack method and attack condition of attack instance can be used to guide the match of pre-condition and post-condition, so as to find the attack path. Attack success rate and attack profit attribute can be used to assist subsequent risk analysis. After simulation tests, the timeliness and availability of the system are verified, and this makes a contribution to the grid network management.

Intelligent Risk Management in Construction Projects: Systematic Literature Review

“…Intelligent management is a management method that incorporates various disciplines and technologies such as artificial intelligence and management science, knowledge engineering, systems engineering, computing technology, communication technology, software engineering and information technology [7]. In addition, at the heart of intelligent management lies the information receiving device in the front section and the embedded control algorithm [31]- [33], which can also definite as Artificial Intelligence (AI). Intelligent management is already in use in a wide range of industries and sectors.…”

“…In this cluster, the main research questions related to the most recent artificial intelligence techniques, with interchangeable cluster labels including knowledge graph; deep reinforcement; and dynamic pricing demand response. [31] built an automated vulnerabilities mining model using knowledge graph technique. First, a knowledge graph was constructed by extracting the basic information of engineering quality results and reasoning these results, resulting in a correlation analysis of information and visualizing the results of information processing.…”

Recent Progress of Using Knowledge Graph for Cybersecurity

“…The KG was used to describe the attack-related resources (e.g., software, vulnerability, ports in use, and privilege of a successful attack) of each host, which would be of great benefit not only to generate the penetration path between hosts but also to integrate collected information of 0-day vulnerability attack for unknown attack prediction. In the power networks, Chen et al [106] generated an expansion attack graph for obtaining the maximum probability vulnerability path and providing the success rate of attacking the power grid and the loss.…”

Optimization of constraint rules for power grid topological relationships based on knowledge graph techniques

“…With the opening of the electricity market and wide access to renewable energy sources, the grid structure and operation mode have become more complex. This requires that the grid topology relationship constraint rules be optimized to adapt to the new operating conditions and ensure the safe, reliable, and economic operation of the grid [7][8][9].…”
