Apache Iceberg: The Definitive Guide

Chapter 12. Governance and Security

As organizations increasingly embrace modern data lakehouse architectures such as Apache Iceberg lakehouses, they benefit from their flexibility, scalability, and performance improvements. However, these advantages bring forth new challenges concerning data security and governance.

This chapter delves deep into the multifaceted world of securing and governing Apache Iceberg tables. Apache Iceberg serves primarily as a standard for how metadata defines a dataset and doesn’t have any security aspects built into it for purposes of security outside of some table properties to select a file encryption type. Securing your Apache Iceberg tables is primarily handled by the storage, access, and compute layers you use to work with your tables.

As you embark on this journey, you’ll discover three critical angles for safeguarding your data lakehouse:

• Securing your datafiles

• Security and governance via a semantic layer

• Security and governance at the catalog level

Organizations must adopt a comprehensive approach to secure and govern their Apache Iceberg tables effectively. By examining these three angles—securing data files, implementing security and governance via a semantic layer, and ensuring catalog-level security—you’ll be well equipped to navigate the complexities of data protection in your modern data lakehouse. So, let’s embark on this journey to fortify your data assets and harness the full potential of Apache Iceberg.

Keep in mind that governance ...
