Security

Securing your Azure App Service is essential in today’s landscape of increasing cyber threats. By default, your Azure App Service is exposed to the public internet, making it vulnerable to attacks like DDoS, Cross-Site Scripting (XSS), and SQL Injection. To safeguard your service, a Web Application Firewall (WAF) is indispensable. This post explores how to implement WAF using Azure Front Door and Cloudflare, comparing their features, costs, and security benefits. Additionally, it provides a detailed guide on preventing bypasses to ensure all traffic to your app service is scrutinized by the WAF, enhancing your app’s security posture significantly.

Ensuring the security of your Azure App Service is crucial for protecting sensitive data and maintaining application integrity. This guide covers key security best practices, including the use of managed identities over credentials in connection strings, securing inbound traffic with a Web Application Firewall (WAF), storing secrets in Azure Key Vault, and implementing regular security updates. We also delve into configuring Cross-Origin Resource Sharing (CORS), setting up access controls with Role-Based Access Control (RBAC), utilizing private endpoints, and adopting Infrastructure as Code (IaC) for change management. These strategies will help you build a robust security framework for your Azure App Service.
