Using Python
Using Python
To remediate the “Cross DB Ownership Chaining Should Be Disabled” misconfiguration in GCP using Python, you can follow the below steps:Note: You need to have the necessary permissions to access and modify Cloud SQL instances in the GCP project.
- Connect to the GCP project using the Python SDK.
-
Get a list of all the Cloud SQL instances in the project using the
list()method of thegoogle.cloud.sql_v1beta4.CloudSqlInstancesServiceClientclass. -
For each Cloud SQL instance, check if the
cross_db_ownership_chainingflag is set toONorOFFby using theget()method of thegoogle.cloud.sql_v1beta4.CloudSqlInstancesServiceClientclass. -
If the
cross_db_ownership_chainingflag is set toON, update the instance’s configuration by creating an instance update request using thegoogle.cloud.sql_v1beta4.types.SqlInstancesUpdateRequestclass and setting thecross_db_ownership_chainingflag toOFF. -
Execute the instance update request using the
patch()method of thegoogle.cloud.sql_v1beta4.CloudSqlInstancesServiceClientclass. - Repeat steps 3-5 for all the Cloud SQL instances in the project.
