Network security groups should limit inbound UDP port 1434 access from the internet
Network security groups should restrict inbound UDP port 1434 access from internet. Network security group provide stateful filtering of inbound/outbound network traffic to Azure resources.
Opening up ports to allow connections from the public internet is generally to be avoided. You should restrict access to IP addresses or ranges that are explicitly required where possible.
