硬件防火墙原理
防火墙分为软件防火墙和硬件防火墙两种。软件防火墙是安装在pc方式的软件产品,它通过在操作系统底层办公来实现网络管理和防护功能的优化。但对G内场上的硬件防火墙产品介绍细心研读后,记者发现,用于硬件防火墙的定义,厂商们好像仍无所适从。大多数厂商对产品的介绍,通常用很多的篇幅向消费者灌注产品的防护功能,而用于防火墙的实践配置,则基本没有提及。查阅G内外很多资料后,发现硬件防火墙通常有着这样的核心请求:它的硬件和软件都需求单独设计,有专用网络芯片来管理数据包;一起,选用专门的操作系统方式,然后避免通用操作系统的安全性漏洞。对软硬件的特殊请求,使硬件防火墙的实践带宽与理论值基本共同,有着高吞吐量、安全与速度统筹的长处。个人简历.doc
(Firewalls are divided into software firewalls and hardware firewalls. The software firewall is a software product installed in the PC mode. It realizes the optimization of network management and protection functions by working at the bottom layer of the operating system. However, after carefully studying the introduction of hardware firewall products on the domestic market, the reporter found that manufacturers still seem to be at a loss for the definition of hardware firewalls. The introduction of the product by most manufacturers usually spends a lot of space to infuse the consumer with the protection function of the product, while the practical configuration of the firewall is basically not mentioned. After consulting a lot of information at home and abroad, it is found that hardware firewalls usually have such core requirements: its hardware and software need to be designed separately, and a dedicated network chip is used to manage data packets; at the same time, a special operating system method is selected, and then a general operating system is avoided. security vulnerabilities. The special request for hardware and software makes the practical bandwidth and theoretical value of the hardware firewall basically the same, and has the advantages of high throughput, security and speed.
