Data Security Framework for Apache Iceberg

This document is a technical report that presents the Iceberg Data Security framework, an enterprise-ready solution designed to enhance data security in Apache Iceberg, an open-source table format for large-scale data analytics. The framework addresses the lack of comprehensive data security features by extending the Parquet Modular Encryption (PME) framework. It outlines critical security capabilities such as pervasive data protection, granular access controls, optimized performance, and integration with existing enterprise security infrastructures. The proposed architecture allows for the serialization of Iceberg tables in Parquet format while maintaining performance advantages. Key requirements include enabling data identification and classification, enforcing access controls based on user context, and allowing the integration of third-party security solutions. The document details the architecture, integration with PME, and configuration parameters necessary for implementing the security framework. It emphasizes the importance of consistent data protection across various environments, particularly for sensitive data subject to regulatory compliance, thereby extending Iceberg's utility in security-sensitive industries.
