Should I turn off port 80?

Should I turn off port 80?

Should I close port 80? If you only want to serve secure traffic via HTTPS and port 443, you should never close port 80. Instead, you should use HSTS – configure your web server to send a Strict-Transport-Security header so that the browser switches to a secure connection.

What happens when you disable port 80?

If we close port 80 it doesn’t stop the client trying to make their initial connection there and this is where the problem lies. Whether or not we as the host have port 80 open, an attacker can still impersonate us and answer the initial query from the client, which never even needs to reach us.

Should port 80 be open on my router?

Port 80 is used for HTTP or Web traffic. If port 80 is closed outbound for your computer, then you would not be able to get to the Internet. If you want to have a FTP server on your computer that is accessible to the outside world you will need to open port 21 on your router or firewall.

Is it more secure to close port 80 and leave port 80?

Honestly you should configure your server to redirect any and all requests to HTTPS only. That way, no matter what the hell they type, it’ll automatically make sure it stays as HTTPS. This is what many sites such as Facebook do, hence the reason why you never have to type the HTTPS when going to their sites.

Is it better to close port 80 or 443?

In theory, closing port 80 might make the system more secure: for example, if you ran a vulnerable version of a server listening on port 80, and a different non-vulnerable version on port 443.

Is it possible to run HTTPS on port 80?

Given that most web server software is written in such a way that it can listen on any port, it seems unlikely that there would be radically different code paths taken though (it’s even possible although uncommon to run HTTPS on port 80, after all).

Are there any sites that have disabled HTTP and blocked port 80?

As far as I know, there are no major sites that have disabled HTTP and blocked port 80. If you do this, you’ll be breaking user expectation (that the site will forward you to a secure site), and since most users won’t know what to do here, because they won’t get a friendly error message, will simply assume your site is broken and move on.
