“…Network technology security is the evaluation and analysis of the system security of the network, such as availability, integrity and confdentiality, and the vulnerability risk of the network. Network technology security measurement is mainly divided into qualitative measurement and quantitative measurement [2,6].…”

“…Wang et al [13] made full use of the advantages of grey analytic hierarchy process to evaluate the network security risk. Te qualitative measurement model has the advantages of convenient evaluation and strong applicability, but human factors have a great impact on the fnal evaluation results, lack of objectivity, and often have the problem of inaccurate evaluation [6].…”

“…Qualitative measurement generally does not use mathematical methods. Te evaluator can directly draw a conclusion on the evaluation network through expert experience and existing knowledge and through the inductive analysis of the current network security situation [6]. Quantitative measurement makes a quantitative judgment on the network security situation by constructing a mathematical model or through a certain quantitative method [7][8][9][10].…”

“…Quantitative measurement makes a quantitative judgment on the network security situation by constructing a mathematical model or through a certain quantitative method [7][8][9][10]. Compared with the subjective judgment of qualitative evaluation, quantitative evaluation can efectively quantify the network security situation, but it requires a lot of data analysis and comparison, and the implementation is more complex [6,11]. Both of them have the problems of weak objectivity and inaccurate measurement.…”

At present, the network security problem is facing a serious threat, and network security events continue to occur. It has become an important link to prevent network attacks and ensure network security. According to the network security protection measures and security technical requirements, it has become an urgent need to establish appropriate security measurement methods and strengthen the monitoring and analysis of network security status. This study proposes a network behavior risk measurement method based on traffic analysis to accurately and objectively evaluate the security state of the network. Traffic is the most basic behavior of the network and the basis of security risk measurement. Firstly, we regard the traffic data as network behavior to build scenarios. Through differential manifold modeling, the traffic data and topology of the network system are semantically described to form a matrix. Then, after manifold dimensionality reduction, the objective risk assessment value can be obtained by manifold mapping and Riemann metric. In this study, the differential manifold theory is applied to network behavior risk measurement, and the innovation of differential manifold in the field of network behavior risk measurement is given. After giving the network behavior risk measurement theory, we first verify the effectiveness of the proposed method through the simulation experiments. Secondly, the public CIC-IDS-2017 data set is used for analysis and calculation to prove the accuracy of the proposed method.

Industrial control systems (ICS) are applied in many fields. Due to the development of cloud computing, artificial intelligence, and big data analysis inducing more cyberattacks, ICS always suffers from the risks. If the risks occur during system operations, corporate capital is endangered. It is crucial to assess the security of ICS dynamically. This paper proposes a dynamic assessment framework for industrial control system security (DAF-ICSS) based on machine learning and takes an industrial robot system as an example. The framework conducts security assessment from qualitative and quantitative perspectives, combining three assessment phases: static identification, dynamic monitoring, and security assessment. During the evaluation, we propose a weighted Hidden Markov Model (W-HMM) to dynamically establish the system’s security model with the algorithm of Baum–Welch. To verify the effectiveness of DAF-ICSS, we have compared it with two assessment methods to assess industrial robot security. The comparison result shows that the proposed DAF-ICSS can provide a more accurate assessment. The assessment reflects the system’s security state in a timely and intuitive manner. In addition, it can be used to analyze the security impact caused by the unknown types of ICS attacks since it infers the security state based on the explicit state of the system.
