| With the rapid development of the Internet,network information security is facing more and more challenges.In the process of network security vulnerability determination,logs play a very important role.However,logs are often the main target of intruders and are easily damaged by tampering,deletion,forgery,etc.,which brings great hidden danger to log security.At the same time,in today’s mainstream distributed logging systems,users usually have no control over the log storage servers being used,which means that log data security has become an urgent issue to be solved.In this paper,a blockchain-based log management system is researched and implemented to solve the problems of log security and sharing in response to the current situation.The main work of this paper is.(ⅰ)research and analyze open-source logging platforms,and implement a blockchain-based storage model based on the open-source platform.Adopting the Ethernet federation chain framework and combining it with the interstellar storage file system,we design a dual-storage model on and off the chain to ensure the advantages of decentralized storage,non-tampering,and traceability of log files.(ⅱ)Based on the security problems caused by the open and transparent decentralized nature of smart contracts,we study the development of access control rules in smart contracts to restrict contract access,and finally realize the access control model based on smart contracts.(ⅲ)The main architecture design,the homogeneous extraction of business requirements,and the design of basic functional modules of the log management system are carried out to finally realize the decentralized log management system based on the Ethernet blockchain.(ⅳ)This paper derives the testing scheme of the system based on the specific implementation of the system,conducts functional and performance tests on the system analyzes the test results and the security of the system,and confirms that the system achieves the expected results and proves that the system is valuable in logging services for enterprise-level management systems and can generate certain benefits. |
