Hi, Please check the following measures. https://learn.microsoft.com/en-us/defender-endpoint/azure-server-integration Application Insights to collect log, performance, and error data for your function app. Restrict unnecessary IP address spaces and listening ports. Leverage Network Security Groups (NSGs) to further lock down surfaces.

DDoS Protection: Enable Azure DDoS Protection Standard and configure Azure Web Application Firewall (WAF) rules to filter malicious traffic. Azure Rate Limiting can further restrict excessive requests. Injection Prevention: Validate and sanitize all user input to prevent exploitation. Use parameterized queries and consider libraries for data handling. Security Best Practices: Implement Role-Based Access Control (RBAC), enforce strong passwords, monitor function app logs, and regularly update Azure Functions runtime and libraries. By implementing these security measures, you can enhance the protection of your Azure Functions against common threats and ensure the security of your applications and data. Remember, security is continuous, so stay vigilant!
