How Do Azure Network Security Groups Work?
NSG is a tool for activating rules that manage traffic to the Virtual networks. Within NSG, an inbound rule refers to incoming traffic requests, while an outbound rule relates to outgoing traffic requests. These rules align with our organizational policy, dictating the permissions for both incoming and outgoing access.
After the creation of NSG, there are default security rules that we can’t change, but we can override those rules with custom rules. By default, NSG allows inbound and outbound traffic from the same virtual network.
Azure Network Security Groups
Network Security Groups (NSG) play a crucial role in securing the virtual environment within Azure. Azure provides various services to help users secure their applications and the infrastructure that users create.
