Help to configure IIS with SSL

Hello,

first of all , congrats.
you can follow below.

Steps to Configure IIS with SSL:

1. Generate a Self-Signed Certificate

Open IIS Manager on the server.

In the Connections pane, click on the server name (root level).

Double-click on Server Certificates.

In the Actions pane (right-hand side), click Create Self-Signed Certificate.

Provide a friendly name for the certificate (e.g., IntranetSiteCert).

Select the Personal certificate store and click OK.

Bind the Certificate to the IIS Site

In IIS Manager, expand the Sites node and select the intranet site.

In the Actions pane, click Bindings.

In the Site Bindings window, click Add.

Choose https as the type, select the self-signed certificate created earlier, and specify the appropriate IP address and port.

Click OK, then close the Site Bindings window.

Enable HTTPS in the Firewall

• Ensure that port 443 (HTTPS) is open in the Windows Firewall to allow secure connections.

• Distribute the Certificate to Users

Since the certificate is self-signed, employees' devices will not trust it by default. To avoid security warnings:

Export the self-signed certificate:

• • Open MMC (Microsoft Management Console) and add the Certificates snap-in for the Computer account.
  • Navigate to Certificates (Local Computer) > Personal > Certificates, find your self-signed certificate, and export it as a .CER file.

Distribute the .CER file to employees.

Instruct employees to install the certificate in the Trusted Root Certification Authorities store:

• • Open the .CER file, click Install Certificate, and choose to place it in the Trusted Root Certification Authorities store.

1. Redirect HTTP to HTTPS (Optional)

• If you want to ensure all traffic is encrypted, set up a redirect from HTTP to HTTPS:

In IIS Manager, select the intranet site.

Double-click HTTP Redirect.

Check Redirect requests to this destination and specify the HTTPS URL.

Check Redirect all requests to exact destination and choose Permanent (301).
