Status of Ports

Hello Everyone

I did a scan of ports and i got the following result:

My Ports 21, 23 and 80 are open.

My Questions are:

1. Is my PC vulnerable?
2. Do i need to stealth it to be secure?
3. How can i stealth the ports?
4. Will stealthing ports 21, 23 and 80 affect Internet usage in any way?

 

Run the same tests from outside your local computer network, i.e. from nmap-online.com.

Your results are common if you run nmap from within your local computer network.

If you have a hardware router and get the same results, then you need to ask the question - how do I stealth my hardware router's ports? - i.e. check your hardware router manufacturer's documentation.

Also, check the scan results from https://grc.com/x/ne.dll?bh0bkyd2 for your ports.

Stealthing those ports should not affect your Internet usage in any way, i.e. all unrequested traffic should be dropped, otherwise, requested traffic should get a response.

A hardware (e.g. router) or software firewall can stealth those ports.
