Method for constructing heterogeneous executive body and system thereof

Abstract

The invention discloses a heterogeneous executor construction method and a system, and the method comprises the steps: carrying out the attack surface measurement of a target mimicry defense system based on an attack surface judgment model, and recognizing an attack surface resource; determining an original heterogeneous component and an original heterogeneous execution body corresponding to the attack surface resource; determining a new heterogeneous component equivalent to the original heterogeneous component; recombining the original heterogeneous executive body based on the new heterogeneous component to obtain a new heterogeneous executive body; after the original heterogeneous execution body is switched into the new heterogeneous execution body, measuring the attack surface, judgingwhether attack surface resources are eliminated or not, if yes, serving the new heterogeneous execution body as a final heterogeneous execution body, and if not, returning to re-determine the new heterogeneous assembly until the determined new heterogeneous assembly can eliminate the attack surface resources. Based on the relationship between the heterogeneous component and the system resource, the attack surface model is used to guide the combination design of the heterogeneous executive body, and the attack surface of the mimicry defense system is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a method and system for constructing a heterogeneous executive body. Background technique [0002] With the automation, intelligence and diversification of network attack technology, traditional defense methods based on feature detection have been difficult to resist uncertain attacks based on vulnerability backdoors, resulting in a precarious cyberspace security situation. In order to reverse the disadvantageous situation of "easy to attack and difficult to defend" in cyberspace, the mimic defense technology with endogenous security features was innovatively proposed. [0003] The heterogeneous executive is an important carrier for the mimic defense system to provide application services. It is a concentrated expression of the heterogeneous characteristics of the mimic defense system and a determinant of the defense capability of the mimic defense system. Therefore, the...
