What Is Oracle Advanced Security?
Oracle Advanced Security delivers comprehensive security features that extend Oracle Database Enterprise Edition’s standard capabilities.
It provides strong encryption and advanced authentication mechanisms, essential for protecting critical enterprise data.
Key Features of Oracle Advanced Security:
- Transparent Data Encryption (TDE): Encrypts data stored on disk (at rest), including specific columns, entire tablespaces, or full database files, ensuring data remains unreadable without proper encryption keys.
- Data Pump Encryption: Protects exported data files during transfer or storage.
- RMAN Backup Encryption ensures that backup files remain secure and encrypted, reducing risks associated with backup theft or loss.
- Network Encryption (historically): Encrypts SQL*Net traffic using native encryption methods (though basic network encryption and TLS support are now free with recent Oracle database versions).
- Strong Authentication Methods: Supports integration with Kerberos, RADIUS, smart cards, and Public Key Infrastructure (PKI) for secure and robust database authentication.
Licensing Requirements for Oracle Advanced Security
Oracle Advanced Security is licensed separately from Oracle EE, and licensing must be explicitly acquired whenever its advanced security features are actively used. It is crucial to clearly understand what triggers licensing requirements.
When Oracle Advanced Security Licensing is Required
Oracle Advanced Security licensing is required specifically when using its flagship encryption features:
- Transparent Data Encryption (TDE): Column-level, tablespace-level, or full database encryption.
- Data Pump File Encryption: Encrypting exported data files via Data Pump.
- RMAN Backup Encryption: Encrypting backup files beyond basic RMAN functionality.
While network encryption historically required Advanced Security, from Oracle Database 19c onwards, basic network encryption (native encryption, TLS) is free with Enterprise Edition and no longer requires the Advanced Security option.

Licensing Metrics for Oracle Advanced Security
Oracle Advanced Security licensing metrics must match the metric used for Oracle EE database licenses—either Processor-based or Named User Plus (NUP):
Processor-Based Licensing:
- Licensing is based on the total processor cores on the database server utilizing Advanced Security features.
- If EE is processor-licensed, Advanced Security must match the exact processor core count.
Example:
- Database server licensed for EE with 12 processor cores.
- Using TDE or RMAN encryption requires explicitly licensing all 12 processor cores for Advanced Security.
Named User Plus (NUP) Licensing:
- Licensing is based on total named users authorized to access the database.
- Oracle’s standard minimum licensing requirement applies: 25 Named User Plus licenses per processor core.
Example:
- Database server with 4 processor cores using Advanced Security features.
- Minimum required NUP licenses: 4 cores × 25 users = 100 NUP licenses.

Detailed Feature Licensing: What Triggers Advanced Security License?
Understanding specifically which actions require an Advanced Security license helps avoid compliance issues.
Advanced Security Licensing Required For:
- Transparent Data Encryption (TDE):
- Column-level encryption (individual sensitive columns encrypted).
- Tablespace encryption (entire tablespace encrypted).
- Full database file encryption.
- Data Pump Encryption:
- Encrypting exported database files via Oracle Data Pump.
- RMAN Backup Encryption:
- Encrypting backup files using RMAN advanced encryption algorithms.
- Advanced Authentication Integrations:
- Implementing Kerberos, PKI, RADIUS, or smart-card authentication.
Advanced Security Licensing Not Required (Included in EE):
- Basic Native Network Encryption (from Oracle 19c onwards):
- Native SQL*Net network encryption (AES256, TLS support).
- Basic Authentication Methods:
- Password-based authentication (default EE authentication methods without advanced integrations).
Practical Licensing Scenario: Healthcare Compliance
Consider a practical scenario involving a healthcare provider demonstrating Oracle Advanced Security licensing:
Scenario Overview:
A healthcare company stores sensitive patient data subject to HIPAA regulations. To ensure compliance, it decided to encrypt data fully within its Oracle database.
Implementing Advanced Security:
The healthcare provider implements:
- Transparent Data Encryption: Encrypts sensitive patient information stored in specific columns and entire tablespaces.
- RMAN Backup Encryption: Encrypts database backups, preventing data breaches from lost backup media.
- Network Encryption: This feature enables basic network encryption (AES256), which is provided free from Oracle 19c onwards (Advanced Security was historically required but is now included in EE).
Licensing Implications:
- The database server is configured with 12 processor cores licensed for EE.
- Due to the use of TDE and backup encryption, Advanced Security licenses are required for all 12 cores, matching EE licensing.
Achieved Benefits:
- Fully compliant with HIPAA regulations through encrypted data at rest.
- Protected sensitive backups, ensuring data confidentiality even in case of loss.
- Ensured legal compliance with Oracle licensing terms, avoiding potential audit penalties.
Common Mistakes to Avoid with Advanced Security Licensing
Proactively avoiding common licensing pitfalls helps ensure full compliance:
- Misunderstanding Network Encryption Licensing: Historically required, basic network encryption is now included free with Oracle EE (19c+).
- Neglecting Licensing for TDE: Transparent Data Encryption use always mandates explicit Advanced Security licensing.
- Partial Licensing: Licensing Advanced Security on fewer processors than the EE database license violates Oracle licensing terms.
Oracle Licensing Audits and Advanced Security Compliance
Oracle frequently audits database environments, particularly focusing on Advanced Security usage due to its high-value encryption capabilities and compliance implications.
Recommendations for Audit Preparedness:
- Document databases where Advanced Security features are enabled.
- Regularly audit internally to match Advanced Security licensing exactly with EE licensing metrics.
- Engage licensing specialists proactively for complex or extensive Advanced Security deployments.
Cost Optimization Strategies for Oracle Advanced Security Licensing
Optimizing Advanced Security licensing costs while ensuring compliance includes:
- Selective Deployment: Deploy Advanced Security features where compliance or security needs justify licensing.
- Evaluate Security Requirements: Clearly define which databases require encryption versus those with lower sensitivity.
- Hardware Optimization: Consolidate databases onto fewer, high-core-density servers to minimize licensing footprint.
Advanced Security Compared to Other Security Options
Advanced Security is distinct from other Oracle security products, such as Database Vault or Label Security:
- Advanced Security focuses on encryption (data at rest, backups) and advanced authentication.
- Database Vault/Label Security: Target access control and fine-grained data security policies, separately licensed options from Advanced Security.
Organizations typically deploy these complementary products alongside Advanced Security for comprehensive database security.
Summary of Oracle Advanced Security Licensing:
- Separately licensed option for Oracle EE.
- Licensing is required explicitly when using Transparent Data Encryption (TDE), RMAN encryption, and Data Pump encryption.
- Licensing metrics (Processor or NUP) must match EE database licenses.
- From Oracle 19c onwards, basic network encryption was free with EE (it didn’t require Advanced Security licensing).
- Licensing mandatory on every database instance where Advanced Security features are activated.
Conclusion
Oracle Advanced Security provides powerful encryption and authentication features for protecting sensitive enterprise data. Understanding its licensing requirements clearly ensures compliance, reduces risks during Oracle audits, and allows organizations to deploy robust data security solutions confidently.
