Oracle Advanced Security

1. Transparent Data Encryption (TDE): TDE enables encryption of data at rest, ensuring that sensitive data remains encrypted on disk and in backups. It helps protect against data theft and unauthorized access to sensitive information.

2. Data Redaction: Data redaction allows organizations to mask or redact sensitive data in real-time based on predefined policies. It helps protect sensitive data from unauthorized viewing by applications or users who do not have the necessary privileges.

3. Secure Network Communications: Oracle Advanced Security offers network encryption and strong authentication mechanisms to secure communication between Oracle databases and clients. It supports SSL/TLS encryption for data in transit, ensuring confidentiality and integrity of data exchanged over the network.

4. Secure Authentication: It supports various authentication methods, including strong authentication mechanisms such as Kerberos, PKI (Public Key Infrastructure), and RADIUS (Remote Authentication Dial-In User Service), to verify the identity of users accessing the database.

5. Fine-Grained Access Control: Oracle Advanced Security allows organizations to enforce fine-grained access controls based on user roles, privileges, and security policies. It provides granular control over who can access specific data and perform specific actions within the database.

Before learning Oracle Advanced Security, it's beneficial to have the following skills:

1. Oracle Database Administration: Familiarity with Oracle Database administration concepts, such as database installation, configuration, maintenance, and security management.

2. Database Security Concepts: Understanding of database security principles, including authentication, authorization, encryption, auditing, and data masking.

3. SQL and PL/SQL: Proficiency in SQL (Structured Query Language) and PL/SQL (Procedural Language/SQL) for interacting with Oracle databases, writing queries, and developing database applications.

4. Networking Concepts: Knowledge of networking fundamentals, including TCP/IP, SSL/TLS, VPN, firewalls, and network security protocols, as Oracle Advanced Security involves securing network communication.

5. Encryption Technologies: Understanding of encryption techniques, algorithms, and protocols used for data encryption, such as AES (Advanced Encryption Standard), RSA (Rivest-Shamir-Adleman), and SSL/TLS.

By learning Oracle Advanced Security, you gain the following skills and knowledge:

1. Data Encryption: Understanding of transparent data encryption (TDE) and the ability to implement encryption for sensitive data at rest, protecting it from unauthorized access and data breaches.

2. Data Redaction: Proficiency in implementing data redaction policies to mask or hide sensitive data in real-time based on predefined rules, ensuring that only authorized users can view sensitive information.

3. Secure Network Communication: Knowledge of securing network communication between Oracle databases and clients using SSL/TLS encryption, ensuring data confidentiality and integrity during transmission.

4. Authentication Methods: Familiarity with various authentication methods supported by Oracle Advanced Security, including strong authentication mechanisms like Kerberos, PKI (Public Key Infrastructure), and RADIUS (Remote Authentication Dial-In User Service).

5. Fine-Grained Access Control: Ability to enforce fine-grained access controls and security policies at the database level, including role-based access control (RBAC) and row-level security, to restrict unauthorized access to sensitive data.
