How is Azure firewall different from network security groups?

The reality is that each service offers security on different network levels, NSGs are responsible to protect Inbound and Outbound network traffic and Firewall can filter network traffic using more intelligence. We can have NSG on a VM and concurrently we can have an Azure Firewall to protect the resources that are running into a VNet.

What are azure security groups?

All users added to Azure DevOps are added to one or more default security groups.Security groups are assigned permissions,which either allow or deny access to a feature or task.Members of a security group inherit the permissions assigned to the group.Permissions are defined at different levels: organization/collection,project,or object.More items…

What is NSG in azure?

Software defined networks are organized around Virtual Networks (VNETs) and subnets. …A Network security group (NSG) contains a list of security rules that allow or deny network traffic in resources it is connected to. …All traffic flows in your network are evaluated using the rules in the applicable NSG.More items…

What is an NSG subnet?

NSGs can be associated with subnets or individual virtual machine instances within that subnet. When an NSG is associated with a subnet, the ACL rules apply to all Virtual Machine instances of that subnet. In addition, you can further restrict traffic to an individual virtual machine by associating an NSG directly to that virtual machine.

How to minimize the number of subnets?

Because network security groups can be applied to subnets, you can minimize the number of them by grouping resources by subnet and applying these groups to subnets. If you decide to apply network security groups to subnets, you may find that existing virtual networks and existing subnets have been defined without considering them.

What happens if the network security group on the subnet has a matching rule to deny traffic?

Network Security Group applied to the subnet: If the network security group on the subnet has a matching rule to deny traffic, the packet will be discarded here , even if the network security group of the virtual machine or the NIC has a matching rule to allow traffic.

What is the IP address of a virtual machine?

Virtual IP of the host node: Basic infrastructure services, such as DHCP, DNS and status tracking, are provided through the IP address 168.63.129.16 of the virtualized host. This public IP address belongs to Microsoft and will be the only virtualized IP address that will be used in all regions for this purpose. This IP address is assigned to the physical IP address of the server machine (host node) that hosts the virtual machine. The host node acts as a DHCP relay, DNS recursive resolution, probe source, load balancer maintenance probe, and equipment maintenance probe. Communication with this IP address should not be considered as an attack.

What is association of a network security group to a virtual machine?

Association of a network security group to a virtual machine (only classical implementations): When you associate a network security group with a VM, the network access rules of the network security group apply to all traffic that enters and leaves the VM. Association of a network security group to a NIC …

Why do you need to define new subnets?

Therefore, you may need to define new subnets and virtual networks to fit the design of network security groups. In addition, you must implement new resources in the new subnets. Then, you could define a migration strategy to move the existing resources to the new subnets.

What port do you need to license a virtual machine?

This will always be done at the 1688 exit port.
