In this chapter, we covered the fundamentals of database security solutions from Oracle. After an overview of the Oracle Database Security solution, we dived into the fine-grained access control and Virtual Private Database. The Virtual Private Database enforces row-level security through the policies and restricts the data access for unauthorized users. Depending on a user's identity and role, the application can set up multitenancy and ensure user isolation as well.
Oracle Database 12c made considerable enhancements to its security offering. The summary of these enhancements was included, while the Data Redaction feature was covered in detail along with demonstrations. In the next chapter, we will dive into another key area that has continuously gained more weight with time: handling of large objects in the Oracle Database. We will be focusing the majority of our discussion around SecureFiles and its optimizations.
