(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.
