Azure features and IP restriction

Question

I would really like to use Azure Functions for the upcoming project, but is there a way to create a whitelist of IP addresses, for example, in ipSecurity in Web.Config?

They use the authLevel function, so there is some protection there. My client has a security requirement for whitelisting.

Looking at the resource explorer, there seems to be an ipSecurityRestrictions property that might work, but I don't see it on an instance of the Azure function.

Unfortunately, since you do not have control over web.config, this is not feasible.

You can perform an ip check inside the function itself or add a solution, such as API control, to block traffic.

If you want to work on a dedicated (rather than a consumption plan), you can expand the runtime functions as a site extension with a modified web.config with the ip whitelist you need: https://github.com/Azure/azure-webjobs-sdk -script / wiki / Deploying-the-Functions-runtime-as-a-private-site-extension
