Course Overview
This Oracle Database 11g: Encryption & Advanced Data Security course is designed to provide students with an understanding of the available countermeasures against threats to data security. Students should consider how encryption technology should, and should not, be employed within an Oracle Database environment in response to known threats and risks. They will understand best security practices, which pertain to application security, host system configuration, and the database installation.
What you’ll learn
Upon completion of the Oracle Database 11g: Encryption & Advanced Data Security course, students will be able to:
- Consider examples of common security threats and sensitive data that might exist within an organization.
- Review the essentials of a sound and secure database installation.
- Recognize known database security weaknesses and how these may be addressed.
- Acknowledge examples of specific attacks that could be launched against individual components within a data center or within the public networks.
- Review the theory and concepts that underlie symmetric and asymmetric encryption.
- Analyze the primary elements involved in asymmetric encryption, including private and public keys, the public key infrastructure, certificates, certificate authorities, and wallets.
- Discuss how symmetric or asymmetric encryption is applied to network traffic, database storage, and external files.
- Examine the limits of encryption strategies and when encryption could be misapplied and counterproductive.
- Discuss the challenges and options available for encryption key storage.
- Apply Transparent Data Encryption (TDE) to tablespace, column, export file, RMAN backup set file, and SecureFile LOB encryption.
- Utilize the Oracle Data Pump access driver to encrypt external tables.
- Configure Oracle Net Services to repel database attacks and implement advanced security using encrypted network communication.
- Implement an application-based encryption solution using the DBMS_CRYPTO() package.
- Consider the types of attacks that can be launched using SQL injection and which countermeasures should be applied to repel these.
- Demonstrate knowledge of enhanced application security using the Virtual Private Database (VPD) facility.
