| Abstract: | A physical isolation system based on PCI (peripheral component interconnect),embedded with intelligence card technology,strong identity authentication technology and security audit,etc.,is introduced.The system can physically isolate the internal and external networks.The hardware of the system,including PCI interface control circuits,network interface circuits and logic control circuits,is designed to automatically adapt its operation speed and mode to the network and securely isolate the internal and external networks;the software of the system,including the security strategy management module,the security audit module,the database record exchanging module,the file exchanging module and the mail exchanging module,is designed to efficiently exchange and manage the data transference between the internal and external networks.Also the driver of the system is implemented with Windows driver development kits (DDK) based on Network Driver Interface Specification (NDIS).The prototype of the system developed has been employed in the Police Fire Protection Bureau of Hubei Province,which performs consistently and efficiently.The technological cruxes discussed have practical values for related subjects. |
