PostgreSQL Flexible Server – Enable Disconnection Logging
This check ensures that the log_disconnections server parameter is enabled for Azure Database for
PostgreSQL Flexible Servers. Enabling disconnection logging allows administrators to monitor client session
terminations and improves auditing, troubleshooting, and security visibility.
Check Details
- Resource: Azure Database for PostgreSQL Flexible Server
- Check: Ensure log_disconnections Parameter Is Enabled
- Risk: If disconnection logging is disabled, unexpected session terminations or suspicious client behavior may go undetected, reducing the organization’s ability to investigate security incidents or performance issues.
Remediation via Azure Portal
-
Log in to the Azure Portal.
-
Navigate to Azure Database for PostgreSQL Flexible Servers and select the affected server.
-
Under Settings, select Server parameters.
- Search for the parameter log_disconnections.
-
Ensure the value is set to ON.
- Click Save to apply the configuration.
Remediation via Azure CLI
-
Open Azure Cloud Shell or a local terminal with Azure CLI installed.
-
Check the current value of the
log_disconnectionsparameter:az postgres flexible-server parameter show \ --resource-group <resource-group> \ --server-name <server-name> \ --name log_disconnections
-
Enable disconnection logging if it is disabled:
az postgres flexible-server parameter set \ --resource-group <resource-group> \ --server-name <server-name> \ --name log_disconnections \ --value on
-
Verify the parameter has been updated:
az postgres flexible-server parameter show \ --resource-group <resource-group> \ --server-name <server-name> \ --name log_disconnections \ --query value
Replace <resource-group> and
<server-name> with your actual values.
The output should confirm that the parameter value is set to
on.
