Problems solved by technology

[0003] The purpose of the present invention is to provide a method, device and system for network attack surface tracking. Firstly, each network node checks the data fragments by itself, extracts exploitable attack vectors, and then collects copies of the data fragments on each network node, and Merge with historical big data, analyze whether there is any abnormality in the data fragments, and whether there is a logical connection between multiple abnormal data fragments, so as to determine and mark the abnormal points and way points, obtain potential attack tracks and security vulnerabilities of network nodes, and solve current problems. There is a problem that the attack surface cannot be traced in the technology

Embodiment Construction

[0037] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0038] figure 1 The flow chart of the method for network attack surface tracking provided by this application, the method includes:

[0039] The server on the network side sends an instruction to each network node, and the instruction is used to instruct each network node to upload the local data segment to the server;

[0040] After each network node receives the instruction, it splits the local data flow through the network node into several data fragment copies, and extracts exploitable attack vectors therefrom;

[0041] Each network node first invokes a local strategy to scan the copy of the data segment to check whether it contains an explo...

Abstract

The invention discloses a method, server and system for network attack surface tracking. Firstly, each network node checks data fragments by itself, extracts exploitable attack vectors, and then collects copies of data fragments on each network node, compares them with historical Merge big data, analyze whether there is any abnormality in the data fragments, and whether there is a logical connection between multiple abnormal data fragments, so as to determine and mark the abnormal points and way points, and obtain potential attack tracks and security vulnerabilities of network nodes, so as to realize The purpose of tracing the attack surface in network nodes.

Description

technical field [0001] The present application relates to the technical field of network security, in particular to a method, server and system for network attack surface tracking. Background technique [0002] The current network communication is facing more and more hidden security issues. Many attacks come from hidden and fragmented forms. The vulnerability points and attack links of a single node will constitute multiple attack surfaces, and the existing methods of preventing network attacks will fail. . Especially the current network usually has a large number of network nodes, and the attacker can disperse the fragments on various network nodes, so as to avoid being discovered. There is an urgent need for a network monitoring attack method that can check the vulnerabilities of nodes and track fragment links. Contents of the invention [0003] The purpose of the present invention is to provide a method, device and system for network attack surface tracking. Firstly,...
