IT Administrators looking to configure their web server to use Port 443.

IT Administrator permissions are required.

Port 443 is the standard port designated for HTTPS traffic, which guarantees that data transmitted between the client and server is encrypted and secure. This is crucial for safeguarding sensitive information and upholding user trust.

This article shows you how you can configure your web server to use Port 443,

1. Configuring Port 443

To enable HTTPS communication on the port:

1. Obrain a valid SSL/TLS certificate from a recognised Certificate Authority (CA).
2. Launch IIS Manager.
3. Navigate to the Server Certificates section.
4. Click Import.
5. Follow the on-screen instructions to add your certificate.

Once you've added your certificate, you need to bind it to the port.

2. Binding the certificate to Port 443

To bind the certificate to the port:

1. Within IIS Manager, select your website.
2. Open the Actions pane.
3. Click Bindings.
4. Click Add in Site Bindings.
5. Set Type to https.
6. Set Port to 443.
7. Select the appropriate SSL certificate from the dropdown menu.
8. Click OK to save the binding.

Ensure that Port 443 is permitted through your firewall settings before finalising the process.

You can verify the HTTPS connection by accessing your site via https://webserverlocation/12_0.
