I trust the firewall very much, because that rule is I personally set, I just want to say, firewall, first shut open again----first all shut down, with what service again open what service.
This management model can be used for border management, but not for the intranet, the total can not let all business to stop first,

Enterprise IntranetFor the risks faced by an enterprise's network security and to fully assess the risks that these risks may bring, they will be the primary problems that must be addressed during the implementation of security construction and the basis and basis for formulating security policies. So what security risks do enterprises have? What value can Enterprise Intranet security products bring to enterprises? Huang Kai, R D Director of Yixin te
Intranet security behavior auditing can find a lot of Intranet security "moles", but there is always a debate in China regarding whether "behavior auditing infringes on personal privacy.
From the perspective of enterprises, deployment Behavior Monitoring and behavior audit products are understandable, which is an important step for enterprise compliance. For example, archive and auditor of a mail are all n
With the rapid development of e-commerce and distance learning, more and more functional requirements for Intranet networks are required. The faster the speed, the higher the security performance. The two main causes of network bottlenecks are network bandwidth and firewall (proxy server) bandwidth. To solve these two problems, an economical and feasible solution is to adopt exchange technology.
Network switching improves the performance of exchange d
It's actually easy to achieve dual-nic Internet access at the same time !!! Please refer to the following !!! In fact, it's easy to do. You only need to add two routes! Open CMD (you should know what it is, start-run-press CMD.) 1. route delete 0.0.0.0 // delete the route 0.0.0.0. Because there is a conflict between the route 0.0.0.0 and the two network segments, the packet does not know which route to be sent, even if it can occasionally access the Internet,> 2. route add 0.0.0.0 mask 0.0.0.0 1
Intranet roaming caused by a system command execution by BYD
I mentioned earlier that there may be many servers running commands on the BYD Internet, and it can also be used as a boundary server to roam the Intranet.

Theoretically, as long as the computer connected to the network is accessible, it is difficult to implement it due to technical level or other reasons. For example, a computer in the LAN only opens Web Services, this service is only available for Intranet users, but there is no direct access for Internet users. Therefore, to allow Internet users to access system services in the LAN, port ing and other operations must be performed. Port ing is often us
