Hello, I am a computer junior at Huazhong University of Science and Technology. Over the past few years, Yingshan's computer network has developed rapidly, and its hardware and software facilities have been in place. However, in a network security test, we found that dozens of computers with vulnerabilities were scanned in less than one minute! The consequence is that computers with vulnerabilities can be easily intruded into by hackers (or even those who know a little about how to use hacking tools. Although the computers in Yingshan are generally installed with "Click driver" + "360 security guard", there is a fatal problem: if the computer date is changed to 1980, it is quite easy to modify the computer date remotely. When hackers make the hacker lose their defense capabilities, they can upload the hacker trojan software to monitor and control users' computers. Computer users' rights and interests will be seriously violated! The following is the computer screen of a user monitored: the monitoring software server used by hackers: in fact, this vulnerability is very simple: many users have not set a password after installing the computer, the default administrator user is used. In this way, hackers can use the User name: Administrator Password: (null) to connect to the user. After the connection, they can remotely operate the user's computer like operating their own computer, including sharing the user's hard disk, upload viruses and Trojans, remotely shut down computers, and so on. The solution is also simple: disable the Telnet service. Note: The Telnet service allows others to log on to your computer over the network. Microsoft designed this service to allow network administrators to manage their computers in other places, but ordinary users don't need it. Instead, hackers are given a chance to use it. Therefore, we will deny it, eliminating worries. The following describes how to disable a service process: the method to disable a service process is actually very simple. Open [start]-> [settings]-> [control panel], and then open [management tools]. find the [SERVICE] and open it. Then, find the [Telnet] option in the service list, right-click it, select [disable] in [start type], and click OK. The following is a sincere hope that you can popularize such a simple security knowledge through appropriate channels. Thank you! We hope to receive your reply.
