Summary
Data classification and analysis helps you know what data you need to protect. It also helps you assess the risks involved in using, storing, and transmitting that data. Every organization has unique data that has distinct security requirements. Unless specific work is done to identify the risks involved in a security breach, the costs and tools needed to protect that data can't be fully understood.
Clean up
The sandbox automatically cleans up your resources when you're finished with this module.
When you're working in your own subscription, it's a good idea at the end of a project to identify whether you still need the resources you created. Resources that you leave running can cost you money. You can delete resources individually or delete the resource group to delete the entire set of resources.
In this module, we turned on Advanced Data Security on an Azure SQL database. This has a monthly cost above and beyond the DB storage itself. If you did this work in your own subscription, make sure to turn this feature off to avoid unexpected costs.
