Core Concepts of Oracle Label Security
1. What is Data Labeling?
Data labeling is the process of categorizing database rows based on sensitivity levels such as “Confidential,” “Restricted,” or “Public.” Labels are metadata that govern access permissions, ensuring only authorized users can view specific data.
2. Security Policies and Clearances
OLS defines robust security policies that regulate user access to labeled data. Each user is assigned a clearance level, dictating their ability to view or interact with specific data categories, thus creating a secure and structured data access model.
3. Fine-Grained Access Control
Data access is evaluated row-by-row, making OLS significantly more precise and secure than traditional table-level or column-level access controls. This granularity ensures that sensitive information remains protected.
