Question

Vijayanandh Vellaichamy · Accepted Answer

Network Security Groups (NSGs) in Azure act as virtual firewalls for controlling inbound and outbound traffic to network interfaces, VMs, and subnets. They allow you to filter network traffic by defining rules that permit or deny communication based on source and destination IP addresses, ports, and protocols. This helps enhance the security of your Azure resources by restricting unauthorized access and protecting against malicious activity.
