    Abstract336)      PDF (1333KB)(311)       Save
    This article is the beginning of a series of articles on active safety network architecture. Since network security problems have root causes in terms of history, culture, technology, etc., it is necessary to start with the root causes in order to find a fundamental solution to solve network security problems well. Through the analysis of the development history and key elements of social control, and the analogy of social security with network security, it is found that network security problems can also be effectively solved by the method of social control principles. In the past, various network security protection theories such as OSI, PDR, P2DR, IATF, and plug-in security protection methods have a certain degree of complement in solving network security problems, and they have not solved network security problems fundamentally; instead, using the new network security protection concepts and methods of social control principles can establish A secure network architecture, make the network generate security capabilities endogenously, solve the fundamental problems of network security well, bring new security values such as main network security protection, unified management and control, and active defense, and significantly improve network security protection capabilities.

    In recent years, with the rapid development of Internet of Things (IoT) technology, a large number of Internet of Things devices have emerged in the cyberspace, such as network printers, network cameras and routers. However, the network security situation is getting worse.  Large-scale network attacks initiated by terminal devices connected to the Internet frequently occur, causing a series of adverse effects, such as information leakage and personnel property damage.  Establishing a fingerprint generation system for IoT devices to accurately identify device types is of great significance to the unified security control of the IoT. We propose a real-time automatic detection and recognition solution for IoT devices based on traffic fingerprints. This solution contains two main modules, including automatic detection and fingerprint recognition.  First, passive listening is used to collect messages sent by different IoT devices. Based on the differences in the header fields of different devices, a series of multi-classification algorithms are used to identify the device type. Simulation experiments show that the scheme can achieve an average prediction accuracy of 93.75%.

The high rate, massive coverage, and extremely low latency of 5G networks make the Internet of Everything possible and bring new opportunities and challenges to network information and security.5G will create new prospects for industry transformation and business models. 5G will be further applied to various vertical industries, such as smart driving, smart grid, and smart healthcare.The 5G architecture is different from the previous 2G/3G/4G architecture and deploy MEC near base stations, which greatly 
    increases security risks. As 5G constructs Internet of Everything scenarios, it faces more risks such as malicious attacks and information theft. This paper analyzes the weaknesses of the 5G network architecture and studies the security penetration framework in 5G networks and proposes the penetration framework of terminal side, RAN side, bearer side, MEC side and core network side.

    With the continuous development of artificial intelligence, deep learning has been applied to vari-ous fields. However, in recent years, relevant studies have shown that deep learning is suscepti-ble to adversarial attacks, which can deceive deep learning models into making wrong judgments about sample categories. At present, the research of computer vision adversarial attack has grad-ually become mature, but because of the special structure of text data, the research of natural lan-guage processing adversarial attack is still in the development stage. Therefore, by introducing the concept of adversarial attack and its application in the field of computer vision, this paper introduces the current research status of adversarial attack in the field of natural language pro-cessing, and investigates popular adversarial attack schemes according to specific downstream tasks of natural language processing. Finally, prospects for the development of adversarial attack in the field of natural language processing are proposed. This paper has reference value for re-searchers in the field of natural language processing adversarial attack.

    Design of the standard architecture of the network security situation awareness
    Journal of Information Security Reserach    2021, 7 (9): 844-848.  
    Abstract309)      PDF (894KB)(265)       Save
    As the real-time guardian of the network security, network security situation awareness platform is the main means to realize "all-weather and all-round awareness of the network security situation". However, being different from the traditional firewall, intrusion detection, security audit and other functions of relatively fixed products, the concept and application of the network security situation awareness is much more complex. Based on the investigation of typical models of network security situation awareness at home and abroad, this paper presents the standard framework of network security situation awareness, focusing on the problems faced by organizations in building network security situation awareness capability and manufacturers in developing and designing network security situation awareness products. It can provide basis for the network security situation awareness R & D, production and testing units to carry out standardized scientific research, production and testing.

    Research and Design of Unified Platform for Vulnerability Management
    Journal of Information Security Reserach    2022, 8 (2): 190-.  
    Abstract380)      PDF (1069KB)(259)       Save
    With the development of the network technology, information security has been paid more and more attention. As one of the most frequently used attacking methods, security vulnerability has also been widely concerned. At present, Most of the organizations or enterprises rely on manual methods to manage vulnerabilities, and do not have unified tracking、 disposition、 display and analysis. These methods are not only inefficient, but also error-prone. A unified platform for vulnerability management was proposed, which allowed the automatic closed loop controlling of the life cycle of vulnerabilities. The platform integrated different vulnerability management capabilities into specific functional modules. General development languages and standards-based service interfaces were developed to allow integration of this platform with other infrastructure platform systems or network security tools. Practices show that, this platform can effectively improve the performance of the vulnerability management, and make vulnerability management to be centralized, streamlined and automated.
