9. Configuring security for Azure Functions

In this chapter, we'll learn a few of the best practices that can be followed while working with Azure Functions, such as the following:

Enabling authorization for function apps
Controlling access to Azure Functions using function keys
Securing Azure Functions using Azure Active Directory
Throttling Azure Functions using API Management
Securely accessing an SQL database from Azure Functions using Managed Identity
Configuring additional security using IP whitelisting

Introduction

Even after the successful development of your application, and alongside continued maintenance and troubleshooting, there remains the concern of app security. Though covering all the security guidelines wouldn't be ...
