I use Windows 10 home on my personal computer. I opened up cmd and ran:
I saw a large list of ports that are on "
LISTEN" mode and some others I couldn't recognize their state as I never learned much Information Security and I just want to filter ports I don't use because I might install Windows software that might listen on them without being aware to that.
Will you agree that minimal usage in Windows10 (SSH via WSL/Putty, web surfing and some PC games requiring web connection and sometimes TeamViewer) justify filtering of all ports besides 22, 80, 443?
In my VPS for example (the one I login to with Putty SSH tunnel, I filtered all ports besides 22, 25 (for Postfix), 80, 443 and 9000 for PHP-FPM) and I wonder if my Windows 10 (on which I don't use port 25 or 9000) should also be that "fortified" by means of port filtering.
