Can I secure notebook outputs?

[arpost]

Greetings, all. I have a notebook for which I am returning an output value to a Fabric data pipeline. I want to ensure that the data in the notebook is secured and the output is secured in such a way that it doesn't get persisted. The data that will be passed will likely be sensitive data. Is this possible?

For reference, I am using the following to output the return value:

notebookutils.notebook.exit({"adf_output_value":r})

Hi @arpost 

Which type of data do you want to secure? Maybe you can consider using Azure Key Vault. Azure Key Vault is a cloud service for securely storing and accessing secrets. A secret is anything that you want to tightly control access to, such as API keys, passwords, certificates, or cryptographic keys. 

You can write secrets in Azure Key Vault using notebooks. In the data pipeline, create a Web activity to get the secret from Azure Key Vault and use it in other activities. Set the Secure Output option to true to prevent the secret value from being logged in plain text. Any further activities that consume this value should have their Secure Input option set to true.
