Data redaction can be implemented without changing application logic, making it a scalable and cost-effective solution for sensitive data protection.

Database Vault: Enforcing Separation of Duties

Oracle Database Vault provides an additional layer of control by restricting access to sensitive data even for privileged users such as DBAs. This is critical in preventing insider threats and enforcing the principle of least privilege.

With Database Vault, organizations can create realms—logical boundaries around sensitive data—that define who can access specific parts of the database and under what conditions. Command controls and rule-based authorizations further refine access management.

By implementing Database Vault, enterprises can satisfy regulatory requirements around segregation of duties and demonstrate auditable compliance with data access controls.

Fine-Grained Access Control (FGAC)

Oracle Database 19c enables highly granular access control through its Fine-Grained Access Control (FGAC) feature. FGAC allows policy-based control over what data a user can access based on contextual variables such as time, IP address, or organizational role.

Unlike traditional role-based access control systems, FGAC allows dynamic enforcement at the row and column level, ensuring users access only the data relevant to their permissions.

For instance, a regional manager might see only sales data for their geographic area, while a global analyst has access to a broader dataset. This level of precision enhances both security and operational efficiency.

Unified Auditing: Centralized Monitoring and Compliance

Monitoring data access and user activity is essential for identifying security threats and proving compliance. Oracle Database 19c introduces Unified Auditing, a comprehensive framework that consolidates auditing for all database activities.

Unified Auditing offers a centralized, tamper-resistant repository for audit records.
