Use Event Grid Private Endpoints#

Security · Event Grid · Rule · 2021_12 · Important

Use Private Endpoints to access Event Grid topics and domains.

Description#

By default, public network access is enabled for an Event Grid topic or domain. To allow access via private endpoints only, disable public network access.

Recommendation#

Consider using Private Endpoints to access Event Grid topics and domains. To limit access to Event Grid topics and domains, disable public access.

Examples#

Configure with Azure template#

  • Set the properties.publicNetworkAccess property to Disabled.

For example:

Azure Template snippet
{
  "type": "Microsoft.EventGrid/topics",
  "apiVersion": "2022-06-15",
  "name": "[parameters('name')]",
  "location": "[parameters('location')]",
  "identity": {
    "type": "SystemAssigned"
  },
  "properties": {
    "disableLocalAuth": true,
    "publicNetworkAccess": "Disabled",
    "inputSchema": "CloudEventSchemaV1_0"
  }
}

Configure with Bicep#

To deploy Event Grid Topics that pass this rule:

  • Set the properties.publicNetworkAccess property to Disabled.

For example:

Azure Bicep snippet
resource eventGrid 'Microsoft.EventGrid/topics@2022-06-15' = {
  name: name
  location: location
  identity: {
    type: 'SystemAssigned'
  }
  properties: {
    disableLocalAuth: true
    publicNetworkAccess: 'Disabled'
    inputSchema: 'CloudEventSchemaV1_0'
