Use valid NSG names#

Operational Excellence · Network Security Group · Rule · 2020_06 · Awareness

Network Security Group (NSG) names should meet naming requirements.


When naming Azure resources, resource names must meet service requirements. The requirements for NSG names are:

  • Between 1 and 80 characters long.
  • Alphanumerics, underscores, periods, and hyphens.
  • Start with alphanumeric.
  • End alphanumeric or underscore.
  • NSG names must be unique within a resource group.


Consider using names that meet Network Security Group naming requirements. Additionally consider naming resources with a standard naming convention. If creating resources using CI/CD pipelines consider programmatically Generating Cloud Resource Names using PowerShell or Bicep


This rule does not check if NSG names are unique.
