The Attack Surface Shifting in the Mimic Defense System
Liqun Wang, Zheng Zhang, Weichao Li, Hao Liu · 2018
The notion of attack surface shifting is introduced to describe the situation of shifting the attack surface in the moving target defense system. However, the situation of shifting the attack surface in the mimic defense system is different from the situation of shifting the attack surface in the moving target defense system. Hence, the existing notion of attack surface shifting can't be applied to describe the situation of shifting the attack surface in mimic defense system. In this paper, we redefine the notion of attack surface shifting for the mimic defense system, and provide a formal method for quantifying the shifting. Experimental results reveal that the new notion of attack surface shifting contributes to improve the strategy of scheduling the heterogeneous redundant executive entity so as to enhance the security of mimic defense system.
