Understand classifications and how to use them inside Atlan
🛡️ What is a classification?
Atlan allows users to create tags called "classifications" for data assets. These tags can be used to apply granular access policies.
As the volume of your data and the number of people using the data increases, classifications can help you ensure the best standards in confidentiality and maintain data security.
Classifications can be used to assign access policies of different kinds in Atlan, such as...
Data protection guidelines such as GDPR and CCPA compliance
Industry information security practices, such as CIA (Confidentiality, Integrity, and Availability) ratings of data assets
Internal custom tags like "Protected", "Confidential", or "Public" data assets
Other groupings of data assets, which you can use to grant access to different users or groups (such as department, function, business line, or project)
📎 Propagate classifications to linked assets
Atlan allows you to propagate classifications from an asset to its linked assets, which saves time and effort. If you enable classification propagation, all related assets (schemas, tables, and columns) will also get automatically classified.
🌟 Pro Tip: Just hover over the classification tag to know if the tag has been propagated and, if yes, from which data asset.
