(Master three simple net commands to ensure network security detection In the process of network security detection, various DOS commands are the most handy tools we can find clues. However, it is not easy to master the use of all DOS commands. Originally, from the point of view of network security detection, we only need to master the three commands to play a better preventive role. ? 1. Detect network connection status? Generally speaking, security is mainly used for computers connected to the network. There are fewer security issues for stand-alone users. For computers connected to the network, the most basic thing is to detect the network connection. Because whether it is a virus, or a Trojan horse, hacker intrusion/intrusion, etc. are all connected through the network. ?In the "Run" window, enter "CMD" and press Enter to open the command prompt window, and then enter "netstat-an", so that all connections established with the machine can be detected. The Proto part indicates the connection method, Localaddress is the local connection address and port, Foreignaddress is the address and port of the other party, and State is the state of the port at that time. ? After understanding this information, we can determine whether there is an abnormal connection, and if so, we need to disconnect the network for further management. 2. Detecting the running status of the service? Each function of the computer usually corresponds to the service it has opened. Therefore, many intruders will open various services after entering the computer. It can be seen that it is necessary to detect the services that the system is running at that time. ? Enter "netstart" at the command prompt, so you can see the system prompt "The following Windows service has been started", and then check whether the unknown service is running from the list. If there is, you can continue to type "netstart service name" to detect more specific information about the service. If it is recognized that it is an illegal service, then only need to run the "netstopserver" command and press the "Y" key to confirm whether it is continuing to operate.
