Research on Intelligent Network Security firewall System solution

[System Overview]

Firewall as the basic equipment of network security system, its function is to cut off the communication backbone of the controlled network, and to handle the security of any communication through the controlled trunk line. At present, there are several types of firewall, such as packet filtering, application agent and State detection.

[System Application]

The security of a firewall depends on whether the firewall is based on a secure operating system and whether a dedicated hardware platform is used. The security performance of the application system is based on the security performance of the operating system. At the same time, the security implementation of the application system directly affects the security of the whole system, and the reliability of the firewall is usually taken in the design, the concrete measures are to improve the robustness of the parts, increase the design threshold and increase the redundant parts. Therefore, the high reliability, with redundant design "EVOC" Industrial computer becomes network security industry and system Integrator's first choice.

The current firewall generally standard three network interfaces, respectively connected to the external network, the intranet and the SSN. The hardware platform is scalable and scalable, and the Intelligent Technology Co., Ltd. specializes in the development and production of network industry users of a variety of single, dual-network, four-port industrial-level motherboards for all network customers to provide a complete choice.

[System Review]

1. All security and services are performed by industrial hardware:

Security software in the operation, storage is not secure, the software running a lot of important information will be clearly in the computer's memory at some time, so the "high level" of criminals steal and use these important information is very easy, so the use of "EVOC" industrial computer built hardware platform, Ensure the security of the entire system.

2. The whole system is practical and reliable:

"EVOC" Industrial computer is based on PC bus industrial computer, can meet the actual needs of integrated business system, reliable and stable operation.
