Edge Network Security Risk Control Based on Attack and Defense Map

Abstract

The standardized communication protocol and the universal application of intelligent electronic devices in edge networks provide technical support to the realization of smart cities and also bring network security issues that cannot be ignored. How to analyze and quantitatively assess the vulnerability of the edge network has become an important issue that needs to be solved urgently in the edge network security risk control. Based on the analysis of the vulnerability mechanism, this paper proposes the selection criteria and generation methods of vulnerability indicators and of composite vulnerability indicators, respectively. In addition, this paper proposes an improved vulnerability severity rating method to analyze the vulnerability of the system and potential security threats. This paper describes the security risk status of vulnerable points based on the state transition of the state offensive and defensive graph and implements the description of the security risk status of attacks in terms of attack frequency, attack success rate and harm. Experimental results justify the effectiveness of the proposed solution.
