Virtual transformation system and method and network security system and method

Abstract

The invention provides a virtual transformation system and method and a network security system and method based on real-time response, and the virtual transformation system comprises a virtual false transformation information configuration unit and a virtual real-time response unit. The virtual false transformation information configuration unit configures false response information which can respond in real time and at least comprises a false network address and a false MAC address according to user configuration information, wherein the virtual real-time response unit constructs a false response data packet based on the false response information to perform false response on the suspicious scanning detection data packet. According to the method, the false response is performed on the scanning detection behavior of the attacker, and the false response can be responded in real time according to the configuration, so that the attacker cannot obtain the topological structure of the network and cannot accurately obtain the real information of the host in the network, the network penetration attack behavior is effectively defended, and the security and stability of the network are maintained.

Description

technical field [0001] The invention relates to the field of network security, in particular to a virtual transformation system based on real-time response, a false response method, a network security system and a network security defense method based thereon. Background technique [0002] With the rapid development of computer networks and information technology, the process of global informatization continues to accelerate, and the network plays an increasingly important role in today's society, becoming a national strategic resource covering important fields such as government, commerce, finance, and communications. At the same time, network security threats are also emerging in an endless stream. Attackers enter the network system through technical means or social engineering methods to carry out information theft, system destruction, malicious deception and other activities, which not only affect the work and life of ordinary people, but also become threats. Major issue...

AI Technical Summary

Problems solved by technology

To a certain extent, the system can provide legality management and behavior audit of intranet resources, and prevent internal attacks and unauthorized access behaviors. However, due to the large number of modules involved and complex deployment, its practicability and versatility are poor.

[0007] In general, the existing detection methods for network penetration attacks cannot achieve good results in practical applications. definite
