Security Threats in Databricks for File Upload

[CAN]

Dear community,

we are using the Azure Databricks service and wondering if uploading a file to the DBFS (or to a storage accessed directly from a notebook in Databricks) could be a potential security threat.

Imagine you upload some files with 'malicious code', macros etc. that could be executed and destroy our databricks setup in any kind. Is that possible/realistic?

Did not really find anything on this, so would be helpful if you guys could share your opinion.

Thank you!

Uploading a file to the Databricks File System (DBFS) or accessing storage directly from a notebook in Azure Databricks could pose potential security risks if not managed properly. Here are some considerations:

1. Sensitive Data Exposure: Uploading sensitive files containing confidential information without proper encryption or access controls could lead to data exposure.

2. Unauthorized Access: If access controls are not configured correctly, unauthorized users may gain access to sensitive data uploaded to DBFS or stored in connected storage.

3. Data Integrity: Uploading files with malicious content could compromise the integrity of the Databricks environment or the data stored within it.

4. Compliance Concerns: Violating data protection regulations or internal compliance policies by mishandling sensitive data could result in legal or regulatory penalties.

To mitigate these risks:

• Implement proper access controls and permissions to restrict who can upload files and who can access them.
• Encrypt sensitive data before uploading it to DBFS or connected storage.
• Regularly audit access logs and monitor for suspicious activities.
• Educate users on best practices for handling data securely within Azure Databricks.

By proactively addressing security concerns, you can leverage Azure Databricks' powerful capabilities while safeguarding your data and infrastructure.
