Implementing Firewall for function apps with inbound HTTPS traffic
Hi Team, We are looking to implement an Azure Firewall for filtering Inbound HTTPS traffic to Azure Function Apps hosted in premium App service plan. Is it possible to use Azure Firewall for this...
Hi
Azure Firewall operate at layer 4 while WAF operate at layer 7 . Since you want to filter https traffic WAF is more suitable .
You can also find in the FAQ this :
Does Azure Firewall support inbound traffic filtering?
Azure Firewall supports inbound and outbound filtering. Inbound protection is typically used for non-HTTP/S protocols. For example RDP, SSH, and FTP protocols. For best inbound HTTP/S protection, use a web application firewall such as Azure Web Application Firewall (WAF).
