Abstract
Description
technical field
[0001] The invention relates to an isolation method and an isolation switch device capable of ensuring logical isolation among multiple networks with different security levels and realizing safe exchange of data between networks, belonging to computer network information security
[0002] technology field. Background technique
[0003] Network isolation (Network Isolation) is mainly to disconnect two or more networks from the physical layer to the application layer protocol, and only exchange the content data through the pure private software interface and hardware isolation components, so as to ensure the security isolation of the network based on data exchange. On the premise of protecting the network environment with high security level, the network isolation technology ensures the security of network information by isolating the connection between networks. Its goal is to ensure that harmful attacks are isolated in a certain local network, and to comple...
