This article mainly introduces what is the difference between the gate and the firewall, which can be used for reference by friends who need it. I hope you will learn a lot after reading this article. Next, let the editor take you to learn about it.

The differences between the network gate and the firewall are as follows: (1) the firewall first ensures the network connectivity, and then considers the security problem, and the network gate exchanges data on the basis of ensuring the security; (2) the firewall is a single-host architecture; the network gate is a dual-host architecture; (3) the network gate is more secure than the synchronization function of the firewall.

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.

Thank you for reading this article carefully. I hope it will be helpful for everyone to share the difference between the gateway and the firewall. At the same time, I also hope that you can support us, pay attention to the industry information channel, and find out if you have any problems. detailed solutions are waiting for you to learn!
