Azure Network Security Group (NSG)

Azure Network Security Group (NSG) is a service that provides a set of rules to control inbound and outbound network traffic to and from Azure resources. NSGs allow you to define rules based on IP address, port, and protocol to manage and secure network traffic within your Azure Virtual Network. These rules can be applied to individual network interfaces, subnets, or entire virtual networks, enabling you to segment and protect your network resources effectively. By using NSGs, you can enforce security policies, restrict access to resources, and ensure that only authorized traffic is allowed to flow to your Azure resources. Network Security Groups are essential for maintaining a secure and controlled network environment in Azure.
