Associate NSGs or clean up#

Operational Excellence · Network Security Group · 2020_06

Network Security Groups (NSGs) should be associated to a subnet or network interface.


NSGs basic stateful firewalls that are deployed as separate resources. Each NSG can be associated to one or more network interfaces or subnets. NSGs that are not associated with a network interface or subnet perform no purpose.


Consider cleaning up NSGs that are not required to reduce technical debt. Also consider using Resource Groups to help manage the lifecycle of related resources together.
