The proxy server settings have many surprising relationships with the IE region.
The Local Intranet Zone is easy to use. It allows TCP/IP to allow servers on the other side of the earth to access the same server as the server on the lower floor .. on the other hand, the question "local" is left to the user or the network administrator to answer. it is easy to guess that when the machine is a local Intranet

In terms of it o M, the security of user behavior should be determined. Finally, when users pass layer-by-layer security checks, in addition, enterprises also need to check the security of their infrastructure configurations to ensure boarding security.

Intranet Security Status Quo Analysis
The theory of Intranet security is relative to the traditional network security. In the traditional network security threat model, it is assumed that all the personnel and devices in the Intranet are secure and trusted, while the external network is insecure. Based on this assumption, Internet security solutions such as anti-
Most enterprises pay attention to improving the border security of enterprise networks, but do not mention their investment in this area, but the core intranet of most enterprise networks is still very fragile. Enterprises have also implemented corresponding protection measures for internal networks, such as installing network firewalls and intrusion detection software that may easily reach tens of thousands or even hundreds of thousands. They also ho
Almost all enterprises have paid more attention to network security. They have successively purchased firewalls and other devices to block security factors from the Internet. However, Intranet attacks and intrusions are still rampant. Facts have proved that the company's internal insecurity is far more terrible than the external harm.
Most enterprises pay attention to improving the border security of enterprise networks, but do not mention their inves
