Technology finance innovation and network security FSS model based on blockchain technology and system assurance engineering

Networks are becoming large and complex structures with the continuous development of communication technology and the proliferation of Internet applications. Network management is made difficult by the diversity of network devices, the dynamic nature of the network, and the unreliability of network elements. Network security is to prevent the potential crisis of the network system. For the network system, the goal of network security is to ensure the security of network data and network resources. Blockchain technology realises peer-to-peer transactions, coordination and cooperation on the basis of decentralised credit, and provides a new paradigm for the security of information content and the security of applications in cyberspace. Blockchain technology can provide a reliable system operating environment even in an unreliable network environment. It is highly transparent, secure and scalable and can be combined with other technologies to provide a secure foundation for network operations. On this basis, the problems encountered in traditional data storage and management should be effectively avoided by using blockchain technology to achieve network information security management. This paper analyses financial innovation and network security architecture through the use of blockchain technology and network community models. The experimental results show that the proposed method can promote the development of financial industry and protect users from network attacks.
