PostgreSQL Flexible Server – Enable Connection Throttling
This check ensures that connection throttling is enabled for Azure PostgreSQL Flexible Servers. Enabling connection throttling helps limit excessive or malicious connection attempts, thereby protecting server stability, performance, and availability.
Check Details
- Resource: Azure Database for PostgreSQL Flexible Server
- Check: Ensure Connection Throttling Is Enabled
- Risk: If connection throttling is disabled, the server may be vulnerable to excessive connection attempts, which could lead to resource exhaustion, degraded performance, or denial-of-service conditions.
Remediation via Azure Portal
-
Log in to the Azure Portal.
-
Navigate to Azure Database for PostgreSQL flexible servers and select the affected server.
-
In the left-hand menu, select Server parameters under Settings.
- Search for the parameter connection_throttle.
-
Ensure the value is set to ON.
- Click Save to apply the configuration change.
Remediation via Azure CLI
-
Open Azure Cloud Shell or a local terminal with Azure CLI installed.
-
Check the current value of the connection_throttling parameter:
az postgres flexible-server parameter show \ --resource-group <resource-group> \ --server-name <postgres-server-name> \ --name connection_throttle.enable
-
Enable connection throttling:
az postgres flexible-server parameter set \ --resource-group <resource-group> \ --server-name <postgres-server-name> \ --name connection_throttle.enable \ --value ON
-
Verify that connection throttling is enabled:
az postgres flexible-server parameter show \ --resource-group <resource-group> \ --server-name <postgres-server-name> \ --name connection_throttle.enable \ --query value
Replace <resource-group> and
<postgres-server-name> with your actual values.
The output should return ON to confirm compliance.
