Problems solved by technology

[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 network node will constitute multiple attack surfaces. The existing methods of preventing network attacks will fail

Embodiment Construction

[0033] 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.

[0034] figure 1 A flow chart of the method for transferring the network attack surface provided by this application, the method includes:

[0035] The server on the network side collects copies of the data fragments of each network node, and extracts exploitable attack vectors from them;

[0036] Merging the received data fragments with the local historical data fragments of the server; the merging includes merging according to at least one standard among the network node to which it belongs, the sending terminal to which it belongs, data type, and corresponding access behavior;

[0037] The server uses an analysis model to analyze the merged da...

Abstract

The invention discloses a method, a server and a system for transferring a network attack plane. The method includes: collecting data segment copies on each network node; extracting available attack vectors; combining the data fragment copy with historical big data; analyzing whether the data fragments are abnormal or not; judging whether logic association exists among the abnormal data fragmentsor not so as to determine and mark abnormal points; obtaining potential attack tracks and security vulnerabilities of the network nodes. When a single network node is discovered to be attacked, the address and the port of the network node are randomly modified, the network node is prevented from being continuously attacked, and other network nodes similar to the network node are protected from being attacked, so that an administrator is helped to transfer attacks while tracking an attack surface in a large number of network nodes, and the normal use of the network node is ensured.

Description

technical field [0001] The present application relates to the technical field of network security, in particular to a method, server and system for transferring a network attack surface. 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 network node will constitute multiple attack surfaces. The existing methods of preventing network attacks will invalidated. 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. [0003] At the same time, after a single network node is found to be attacked, how to prevent the network node from being continuously attacked, and how to protect other network nodes close to the network node from being attacked. These become urgent technical problems to be so...
