Windows VPS/server quickly changes the default 3389 port to improve security performance

Generally, the VPS and server installation LiNUX systems selected by our users will default to port 22, while Windows systems generally default to port 3389, and some service providers will set other fixed or random ports. From a security perspective, when we set up server security, we need to modify the default port to at least ensure the automatic scanning behavior of some software.

Last night, a netizen contacted Snail and said that there was a problem with his Windows server. When he logged in to his server desktop, he saw that there were indeed some more files, and they kept sending out packages. To ensure safety, it was recommended to reinstall the system. Of course, the premise was to back up the system. data. Then the port needs to be modified in the security measures. In fact, the password setting of this student is too simple, just a few numbers... so. By the way, I took a screenshot when I helped modify the port and compiled it into this article. At least I will update it with some content.

First, enter the registry

,

According to many tutorials, we need to enter the folder step by step and then find it. (HKEY_LOCAL_MACHINE\\\\System\\\\CurrentControlSet\\\\Control\\\\Terminal Server\\\\WinStations\\\\RDP-Tcp)

In fact, we don’t need to be so complicated. Just go to Edit-Search, PortNumber character, and then find it.

Second, modify the default port 3389

The default here is in hexadecimal, and what you see is not numbers. Here we choose decimal to see numbers. Then modify the port you need and save it.

Finally, restart the server to take effect, and we can log in using the new port. Of course, modifying the port is only a simple security factor. Others, including software security and other security measures, also need to be paid attention to.
