Block chain-based network active defense method, system and computer-readable storage medium

Abstract

The present invention relates to the application field of block chain processing technology, and provides a block chain-based network active defense method, system, and computer-readable storage medium. The storage medium stores a computer program, and the computer program implements the method when executed by a controller. A smart contract with screening criteria is built on the client side, which is used to query the analysis node on the background control side and perform coverage awareness on its smart contract, so as to automatically monitor abnormal smart calls, cross-contract attacks, overflow attacks and other behaviors. Once the abnormal behavior is found, the system immediately calls the analysis node to obtain the crawler logic in the storage contract, recursively captures the abnormal call node, collects the data of the attacker to trace the source of the attacker's information, and according to the obtained attacker's information Call the pre-stored matching defense contract to realize active defense. Since the network active defense method is built on the block chain, it has high stability in the case of easy update.

Description

technical field [0001] The present invention relates to the application field of block chain processing technology, and in particular to a computer-readable storage medium and a system. The computer-readable storage medium stores a computer program, and when the computer program is executed by a controller, a block chain-based network active defense method is realized. . Background technique [0002] Active defense technology is a proactive defense, which mainly implements defensive measures in advance, so that the attacker cannot reach the attack target. It can also be understood that the system can prevent it well and avoid threatening the security computer without the need for artificial passive response. The database situation occurs. Today, with the wide popularization and in-depth application of computers, the application of active defense technology has brought network security protection into a new stage, and it is also an important means and development trend of ma...

Problems solved by technology

However, with the development of network defense systems, more and more decompilation technologies aimed at cracking network defense systems make network attack techniques more diverse. In order to deal with complex and diverse network attacks, network security systems are often equally large and complex, and often require Update, its own stability is difficult to guarantee, which brings hidden dangers to network security
