The hardware firewall mentioned here is a professional firewall, * detection, active defense, virus protection, in addition to these basic, there are antivirus libraries, for virus detection. Such hardware firewalls are generally more than ten thousand, or even tens of thousands too large. What kind of LAN environment is needed? There is no doubt that the economy must be a well-off local area network. Technically and necessary.

In fact, it is necessary that the local area network has WEB services published on the external network, such as WEB server, mail server and so on. In this way, you can access each other directly from the interconnection, and you are easy to encounter × × ×, × × ×, such an environment, no matter how big or small, do not be stingy, buy a hard defense, powerful and advantageous.

However, if it is only an ordinary local area network, there is no server that needs external access, and some routes cannot even access the internal server even outside the port mapping.

Then there is no need to install a hardware firewall. Even if there is ERP, networking, and the use of professional hardware firewalls, technology is really not important. Domestic operators have banned the common port 80 and cannot be connected directly through port 80. The ordinary local area network should pay attention to the internal network security, the internal network security protection is good, the external network naturally will not have any problems. The so-called safety, the so-called protection, and the so-called behavior management of the Internet do not mean that there is a problem with the local area network, but that the Internet usually establishes a good Internet order, standardizes the behavior and content of the Internet, and develops good habits of surfing the Internet. the network is naturally healthy and smooth.

The focus on intranet security has also given rise to a new title, that is, the next generation firewall. First of all, it must be a firewall gateway (X86 architecture), not routing, and high-end routing is not a gateway.

1. The content on the Internet is truthfully recorded and can be checked.

two。 A variety of network software, games, video, mobile APP, all in the grasp, flexibility to allow it to run or not to run, this is more focused on an online behavior management of employees.

3. Intranet security filtering, this is very important, at present, the domestic professional and technical operation and maintenance can do for you, and are for state-owned enterprises, central enterprises such as units. Many viruses come from web pages. URL library filtering is the mainstay of intranet security, and tens of millions of address library support also demonstrates the professionalism of the system. The growth of such an address library requires professionals to study and classify it every day, so it is reasonable for many gateways to charge a certain number of servers every year. (we do not accept it, we are free of charge, professional R & D institutions have to study whether products are sold or not, and give welfare to customers.)

4. Intranet security is not built above infrastructure, then how to manage later, combined with the needs of various administrative systems, this is the safety first, and then people-oriented.
