      Log Connections Disabled

      Risk Level: Low

      Description:

      For PostgreSQL servers, this plugin guarantees that connection logs are enabled. All attempted and successful connections to the server are reported in connection logs. Only admin users have permission to change this parameter at the session start and it cannot be changed during an access session.

      Recommended Action: Ensure the server parameters for each PostgreSQL server have the log_connections setting enabled.

      About the Service :

      The PostgreSQL Community Edition database engine powers Azure Database for PostgreSQL, a relational database service in the Microsoft cloud. Azure Database for PostgreSQL includes built-in quality, data protection, and automated maintenance for the underlying hardware, operating system, and database engine, among other features.

      Impact: 

      If this feature is disabled then no attempted connections will be logged and there will be no logging data which will lead to failure in identifying, troubleshooting, and repairing configuration errors and sub-optimal performance for your Microsoft Azure PostgreSQL database servers.

      Steps to Reproduce :

      1. Sign in to Azure Management Console.
      2. Navigate to the Azure All Resources portal at: https://portal.azure.com/#blade/HubsExtension/BrowseAll
      3. From the Type filter available at the filter bar, select the resource type as only Azure Database for PostgreSQL server.
      4. Select the name of the PostgreSQL database server that you want to examine from all the listed servers.
      5. In the navigation panel, select Server Parameters.
      6. In the search bar, search for log_connections.
      7. Check if the value of this parameter is set to ON or OFF.
      8. If it is set to OFF, then the "log_connections" server parameter is not enabled for the selected Azure PostgreSQL database server.
      9. Repeat steps no. 3 – 8 for each PostgreSQL database server provisioned in the current Azure subscription as well as in other subscriptions in your Microsoft Azure cloud account.

      Steps for Remediation :

      1. Sign in to Azure Management Console.
      2. Navigate to the Azure All Resources portal at: https://portal.azure.com/#blade/HubsExtension/BrowseAll
      3. From the Type filter available at the filter bar, select the resource type as only Azure Database for PostgreSQL server.
      4. Select the name of the PostgreSQL database server that you want to examine from all the listed servers.
      5. In the navigation panel, select Server Parameters.
      6. In the search bar, search for log_connections.
      7. Toggle the value of this parameter to ON.
      8. Click Save to save the changes.
      9. Repeat steps no. 3 - 8 to reconfigure other PostgreSQL database servers provisioned in all your Azure subscriptions.
