Learn Azure Application Security Group explained with DEMO in 20 Mins
You can use an Azure network security group to filter network traffic to and from Azure resources in an Azure virtual network. A network security group contains security rules that allow or deny inbound network traffic to, or outbound network traffic from, several types of Azure resources. For each rule, you can specify source and destination, port, and protocol.
Application security groups enable you to configure network security as a natural extension of an application's structure, allowing you to group virtual machines and define network security policies based on those groups. You can reuse your security policy at scale without manual maintenance of explicit IP addresses. The platform handles the complexity of explicit IP addresses and multiple rule sets, allowing you to focus on your business logic.
Application security groups have the following constraints:
There are limits to the number of application security groups you can have in a subscription, as well as other limits related to application security groups.
You can specify one application security group as the source and destination in a security rule. You cannot specify multiple application security groups in the source or destination.
All network interfaces assigned to an application security group have to exist in the same virtual network that the first network interface assigned to the application security group is in. For example, if the first network interface assigned to an application security group named AsgWeb is in the virtual network named VNet1, then all subsequent network interfaces assigned to ASGWeb must exist in VNet1. You cannot add network interfaces from different virtual networks to the same application security group.
If you specify an application security group as the source and destination in a security rule, the network interfaces in both application security groups must exist in the same virtual network. For example, if AsgLogic contained network interfaces from VNet1, and AsgDb contained network interfaces from VNet2, you could not assign AsgLogic as the source and AsgDb as the destination in a rule. All network interfaces for both the source and destination application security groups need to exist in the same virtual network.
Augmented security rules
Augmented security rules simplify security definition for virtual networks, allowing you to define larger and complex network security policies, with fewer rules. You can combine multiple ports and multiple explicit IP addresses and ranges into a single, easily understood security rule. Use augmented rules in the source, destination, and port fields of a rule. To simplify maintenance of your security rule definition, combine augmented security rules with service tags or application security groups. There are limits to the number of addresses, ranges, and ports that you can specify in a rule.
