SSL is required for security reasons in versions 2.8 and higher. Non-SSL installations can be considered risky from a security point of view. Therefore, we definitely do not recommend using SSL without it. The use of SSL has become mandatory as a standard in web applications all over the world.
If you have a work that only serves internal users, you can install SSL on IIS by following the steps below.
Step: 1 Go to the Start menu and click Administrative Tools > Internet Information Services (IIS) Manager.
Step: 2 Click the server name in the Connections column on the left and double-click Server Certificates.
Step: 3 Click Create Self Signed Certificate in the Actions Column on the right.
Step: 4 Type any meaningful name and then click OK to continue.
Step: 5 Click OK. Once this is complete, you should see SSL in the Self-Signed certificates list. You now have an IIS Self-Signed Certificate with 1-year validity.
Result: Finally, by following the above step, your Self-Signed Certificate is ready in IIS.
