What is the difference between port 443 and 80?
strong security
The main difference between Port 80 and Port 443 is strong security. Port-443 allows data transmission over a secured network, while Port 80 enables data transmission in plain text. Users will get an insecure warning if he tries to access a non-HTTPS web page.
Why would port 80 be open?
One of the main reasons to keep port 80 open is to continue to redirect traffic from HTTP to HTTPS. We have to keep port 80 open to redirect any traffic that might attempt to connect there first, for whatever reason that might be.
Is it OK to have port 80 open?
There is nothing insecure about port 80 being open. Security issues only occur when the web server is serving requests over an unencrypted connection, especially if those requests contain sensitive data. Having port 80 be open and send nothing more than an HTTP redirect (301) is perfectly safe.
Do you send redirects to port 80 or 443?
They should also send redirects for all port 80 requests, and possibly an HSTS header (on port 443 requests). Allowing port 80 doesn’t introduce a larger attack surface on your server, because requests on port 80 are generally served by the same software that runs on port 443.
Why is it important to keep port 80 open?
One of the main reasons to keep port 80 open is to continue to redirect traffic from HTTP to HTTPS. Even with HSTS and preloading there are still several reasons we can’t rely on them. To start with, the browser on the other end might not implement the preload list, this means they will still default to HTTP on port 80 and miss out on a redirect.
What does bad request at port 443 mean?
This means, that the server expects a TLS handshake at port 443. The server detects that it does not get the TLS handshake but a HTTP request instead and returns the “Bad Request” message to the client, explaining that it is the wrong kind of request to this port.
