摘要
提出了一种基于嵌入式系统的安全网卡设计方案。通过在网卡上引入SoC和嵌入式系统,在网卡上集成了嵌入式防火墙、网络隔离设备、硬盘保护与恢复及加密机等网络安全产品。并可以根据实际的需要,对嵌入式安全网卡的功能进行扩充和裁减。
In order to provide host-dependent security enforcement and prevents host from being used as a launching pad for further invasion into the network, an embedded security network card is designed. Each card has an onboard SoC (system on chip) processor and embedded system that enforce security by integrating firewall, network isolation tool, hard disk protection tool and encrypt machine. This embedded security network card plugs into the standard PCI slot, replacing the conventional network card and offloading the TCP/IP stack and security function from the operating system, so it improves system performance and expands network security tremendously. The most special feature of the card is that its security functions can be extended or reduced according to practical demands.
