Reviewing Authorization on a Production Volume

Starting the Review

I started my morning by reviewing the authorization settings on a production volume that our team had recently deployed. This volume, named production.files.landing, is used to store raw data ingested from various sources. Understanding who has access and what permissions they have is crucial for maintaining security and compliance in a production environment.

Describing the Volume

I ran the first command to describe the volume and get an overview of its metadata. This helps me confirm the correct volume name and its configuration.

DESCRIBE VOLUME production.files.landing;

<

name	catalog	database	volumeType
documents	production	files	MANAGED

The output confirmed that the volume is named documents, resides in the production catalog, and is part of the files database. It is a MANAGED volume, which means it is fully managed by Databricks and not a cloud storage volume.

Checking the Grants

Next, I wanted to check the grants assigned to this volume to understand who has access and what permissions they have. This is essential for verifying that only authorized users and groups can interact with the volume.

SHOW GRANTS ON VOLUME production.files.landing;

principal	actionType	objectType
data_engineers	READ VOLUME	VOLUME
data_engineers	WRITE VOLUME	VOLUME

The output showed that the group data_engineers has both READ VOLUME and WRITE VOLUME permissions. This means they can read from and write to the volume, which is appropriate for a landing zone where data is ingested and processed.

Verifying the Configuration

I verified that the grants align with our team’s access requirements. The data_engineers group is the only one with permissions, which ensures that no unnecessary users have access to the volume. This setup helps maintain the integrity and security of the data stored in the production environment.

By reviewing the volume’s metadata and grants, I made sure that the access controls are correctly configured and that the volume is ready for use in our production pipeline.
