Redis Cache should restrict public network access

High Azure General redis-no-public-access

Applies to

Microsoft.Cache/redis

What CGPulse checks

A resource passes this rule when publicNetworkAccess must equal Disabled. Anything else is reported as a finding with the evaluated property value attached as evidence.

How to fix it

Disable public network access to prevent unauthorized internet exposure. In Azure Portal: Redis Cache > Networking > set Public network access to Disabled. See: https://learn.microsoft.com/en-us/azure/azure-cache-for-redis/cache-private-link

Careful: Disabling public access blocks all connections not using private endpoints

CLI

az redis update --ids "{id}" --set publicNetworkAccess=Disabled

Terraform

resource "azurerm_redis_cache" "{name}" {
  name                          = "{name}"
  resource_group_name           = "{rg}"
  location                      = var.location
  capacity                      = 0
  family                        = "C"
  sku_name                      = "Basic"
  public_network_access_enabled = false
  # Match sku to your Redis tier (Basic/Standard/Premium)
}
