Survey on Key Technology of Multi-Network Data Security Ferry System

The implementation of the Network Security Law and the Data Security Law has opened a new chapter in the era of innovation based on the application of information technology, and this study proposes to use virtualisation technology for network isolation in order to build a multi-network data security exchange system. The system adopts special protocols for data transmission, controls user access and use through user authentication and permissions, uses a flexible customised approval process, and undergoes mandatory sensitivity checking and anti-virus checking to ensure the security of the data itself. During operation, it adopts detailed behavioural and content auditing, and flexibly interfaces with user authentication servers. The system's operating interface is similar to that of Baidu.com so that it is easy for users to operate.
