Really physically isolated
The Chinese network physics isolation gate truly realizes physical isolation between two networks. Physical isolation network gate interrupts the direct connection between the two networks, all data exchange must be backed from the seventh floor of the network gate to the original data (file) by physical isolation mesh, the network gate is restored as the original data (file), and then "ferro" "The form is to deliver data. There is no package, command, and TCP / IP protocols can penetrate physical isolation mesh. This is the essential difference between this with the transparent bridge, mixed mode, IP over usb, and through switching methods, and the nature of the nature, truly realize physical isolation.
Clock switch
Physical isolation is achieved by a switch. At present, there are three types of physical separation technologies: Real-Time Switch, One-Way Link, and Network Switch. The real-time switch and one-way connection speed are fast, and the speed of the network switch is slow. People generally have concerns about switching speed, worried that the switching speed directly affects the performance of the network. If the speed is low, the performance of the network is definitely affected. Even if the speed is high, the performance of the gatekeeper is also limited by the host performance. Regardless of the high low of the switching speed, the upper limit of the performance of the gatekeeper will not exceed the upper limit of the host.
The Chinese network physics isolation network gate is implemented in the system's kernel by using the host's CPU clock, and successfully reaches the highest performance of the gatekeeper, better than common three switching technology. The kernel is more efficient than the efficiency of peripherals.
Anti-attack kernel physics isolation network gate interrupts direct physical connections of two networks, so known attacks and unknown attacks will not attack the physically isolated network. However, physical isolation equipment itself involves a part of the invisible network or will be affected by an invisible network. Physical isolation network gates can protect others, but they can't avoid themselves being attacked. Just like a firewall, you can protect others and cannot protect the firewall itself. Physical isolation network gate itself is very important. In addition to the special safety operating system, in addition to safely reinforcing and minimizing the service, in addition to safely reinforcement and minimizing the service, Chinanet has an unicard-resistant attack kernel, ensuring that China's physics isolation network gate has The highest anti-attack characteristics.
Fully support all Internet standards (RFC) physical isolation mechanisms require stripping all TCP / IP protocols to prevent attacks from protocols. From the IP protocol, to the TCP protocol, with a session (session) as a unit, to the seventh layer application layer (Application), and finally restore the file format that can be stored to "ferry" through the low-level physical media. The internet physics isolation mesh gate, according to different applications, completely follow the associated Internet standard RFC. According to the relevant RFC, one application is implemented.
The protocol-based content detection is working to the seventh layer due to the physical isolation of the network gate from the network, so the content can be checked based on the protocol. Different applications, the specifications of the seventh floor are different, and the mechanisms and modules of the inspection are also different. The inspection can include, but is not limited to, content filtration, anti-virus, anti-malware, anti-discipline, file format control, etc.
Support for identity authentication network physically isolation network brakes, to protect high-security requirements from attacks from untrusted networks, determine the network of high security requirements must support identity authentication. In order to ensure the trusted and reliability of the gate configuration, you must initiate a configuration request from a trustee, and you must authenticate. In order to prevent the occurrence of leaks, the user of the credible network must also be authenticated. For some specific applications, identity authentication can also be required.
User benefits High Security Physical Isolation Gates is known as the highest security products in all security products. Its philosophical thinking is unsafe to disconnect. The use of the network is considered if secure security is considered. Avoid attacks from operating systems, commands, protocols. The highest bandwidth of the high-bandwidth network physics isolation gate can be up to 5G. The effectiveness of the existence of most physical isolation network gates is solved.
High availability internet physically isolation network gate supports the dual communication function of the hot standby system, providing extremely high availability. It supports dual power supply.
Application Play High Security Access Access Service Which of the units and departments of access to the Internet is required for security reasons, which can provide access services. Internal users can access the Internet, the Internet cannot invade and attack internal networks. The services provided include Web site access, email transceivers, file downloads and other services.
Protecting websites, databases, and core assets For those who provide e-commerce and e-government, they must provide access services and solve security issues. Physical isolation network brakes can be resolved in the website or database.
The physical isolation between the two networks is a large number of private networks and public networks, and the intranets and security issues are needed. In the use of China-network physical isolation mesh, the necessary data communication between the two networks can be achieved, but also guarantees that there will be no security issues in each other.
