1. Log in to the Google Cloud Console and navigate to the Cloud SQL Instances page.
2. Select the SQL Server instance that you want to remediate.
3. Click on the “Edit” button at the top of the page.
4. Scroll down to the “Flags” section and locate the “user connections” flag.
5. Change the value of the “user connections” flag to “0” to set it to a non-limiting value.
6. Click on the “Save” button at the bottom of the page to apply the changes.

​

1. Open the Cloud Shell by clicking on the Cloud Shell icon located in the top right-hand corner of the GCP Console.
2. Run the following command to connect to the SQL Server instance:
   gcloud sql connect [INSTANCE_NAME] --user=[USER_NAME]
   
   Replace [INSTANCE_NAME] with the name of your SQL Server instance and [USER_NAME] with the name of your SQL Server user.
3. Once connected, run the following command to set the SQL Server User Connections flag to a non-limiting value:
   EXEC sp_configure 'user connections', 0
   RECONFIGURE
   
   This will set the maximum number of user connections to 0, which is a non-limiting value.
4. Verify that the flag has been set correctly by running the following command:
   EXEC sp_configure 'user connections'
   
   This should return a value of 0 for the maximum number of user connections.
5. Exit the SQL Server instance by running the following command:
   exit
   
   This will disconnect you from the SQL Server instance.
6. Verify that the misconfiguration has been remediated by running a vulnerability scan or reviewing the configuration settings for the SQL Server instance.

1. Connect to your GCP project using the Python SDK and authenticate with your credentials.
2. Identify the SQL Server instance that has the misconfiguration.
3. Use the Cloud SQL Admin API to update the userConnections flag to a non-limiting value.
4. Verify that the flag has been updated successfully.

• GCP_REGION with the instance region.
• db-custom-2-7680 with your desired tier.
