What happens when port 445 is closed?

Port 445 is for shared folders and printers. Closing it affects local area network sharing. If it is not needed, it can be closed.

Let's start with port 445:

Port 445 is the net File System(CIFS), port 445 is a mixed port, it is with port 139

Is the main channel for IPC$intrusion. It gives us easy access to shared folders or shared printers in a local area network, but it's also because of it that hackers can secretly share your hard drive through this port and even format your hard drive silently! All we can do is figure out how to block the hacker's opportunity and block the port 445 vulnerability.

There are three main methods, the first is relatively simple through the firewall; the second is also very simple through the registry; the third is a little more complex by modifying ip security policy
