This article will explain in detail what is the difference between gates and firewalls in the Internet. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

The network gate, like the firewall, is the security guard of the network security boundary, and its role can not be ignored. But what are the differences between them? This article focuses on the difference between gateways and firewalls.

The operating environment of this tutorial: windows7 system, css3&&html5 version, Dell G3 computer.

The differences are as follows: 1. Differences in application scenarios

Firewall: the firewall should first ensure the connectivity of the network, followed by the security issue.

Network gate: the network gate is to exchange data on the basis of ensuring security. The network gate is that the two networks already exist, and now the two networks have to be interconnected, and the interconnection is necessary to ensure security. The network gate is now the only product with the safest network boundary security isolation. Only the network gate can solve this problem, so the network gate must be used.

2. Hardware difference

The firewall is a single-host architecture, the early use of packet filtering technology, the network gate is a dual-host 2x1 architecture, through the private protocol ferry for data exchange, session-based detection mechanism, because the network gate is a dual-host structure, even if the external network end is breached, due to the internal use of private protocols, there is no way to attack the internal network, the firewall is a single-host structure, if attacked It will cause the intranet to be completely exposed to others.

3. Functional differences

The network gate mainly contains two kinds of functions, the access class function and the synchronization class function, the access class function is similar to the firewall, the network gate is more secure than the firewall is the synchronization class function.

This is the end of the article on "what's the difference between gates and firewalls in the Internet". I hope the above content can be of some help to you, so that you can learn more knowledge. if you think the article is good, please share it for more people to see.
