Azure Classroom Series – 31/Aug/2021

Network Security Group

• Lets try to create a network with 6 subnets

• Now if we want to create a rule in such a way that web subnet can be communicated from any resource in AppGateway, Management, Business Subnet

• In this case creating a rule at subnet level is better as it has to be applied to all resources in subnet.

• NSG can be applied at subnet level also

• Now lets create deny rules for AD and db subnets

• Attach nsg to web subnet

• Now create a nsg rule for business subnet which should not allow inbound connections from application gateway subnet.

• Exercise:

  • Create a network diagram with 3 subnets
    • Web
    • App
    • Db
  • Try to depict the communication in the diagram
