Data Security

Role-Based Access Control (RBAC) and Policy-Based Access Control (PBAC)

  • Application: Employing Role-Based Access Control (RBAC) and Policy-Based Access Control (PBAC) within RAG systems to manage data access securely and efficiently. RBAC provides a structured way to assign data access based on user roles, ensuring that individuals only access data pertinent to their role in the organization. PBAC adds another layer by enabling access control based on specific policies, which can include contextual factors and conditions. This dual approach allows RAG systems to dynamically adapt access rights, ensuring secure and appropriate data access in various scenarios.
  • Key Benefit: Enhances data security in RAG systems by allowing precise control over who can access what data and under which circumstances. This combination of RBAC and PBAC ensures that data access is both compliant with organizational policies and adaptable to specific context, thereby improving both security and operational efficiency.
  • Tools/Solutions:

Policy enforcement with GenAI

  • Application: Enhancing RAG systems with an internal GenAI engine for dynamic user permission assessment. The engine analyzes user roles, cross-references internal role descriptions, and evaluates the data requested to determine if additional approval is necessary. This approach adds a layer of intelligent, context-aware safeguarding to traditional authorization methods.
  • Key Benefit: Provides an extra layer of security by contextually assessing data access requests, ensuring compliance with data policies.
  • Tools/Solutions:

Master Data

Reference Data Management

  • Application: Utilizing Reference Data Management systems within the context of RAG systems. This involves enriching RAG systems with essential lookup data that aids in creating categories, hierarchies, and business translations. Reference Data Management systems provide a transparent and manageable approach for handling these crucial manually-supported data elements.
  • Key Benefit: Enhances the RAG system’s functionality by introducing structured, reliable reference data, aiding in more accurate categorization and business interpretation, which is vital for data-driven decision-making.
  • Tools/Solutions: For Reference Data Management: Amazon DataZone, Open Data Discovery

Bias-Mitigated Single Source of Truth

  • Application: Establishing a robust Master Data Management (MDM) system as a single source of truth for RAG systems. This approach focuses on identifying and prioritizing the most reliable and curated data sources, thereby reducing the risk of biased data influencing RAG’s operations.
  • Key Benefit: Ensures RAG systems rely on the most accurate, up-to-date, and unbiased data, enhancing the quality and reliability of retrieval and augmentation processes.
  • Tools/Solutions:
    • For Master Data Management: AWS Data Exchange for managing and sharing curated datasets, ensuring RAG accesses only high-quality data sources.
