In a previous blog post, I provided a recipe for enforcing encryption for data-at-rest. However, it is important to remember that Transparent Data Encryption (TDE) protects your data from bad actors, who might have illegally gained access to the data files. Data exists unencrypted when loaded and accessed in the database. Malicious attacks can come from internal sources as well. When storing user confidential information, data stewards need to take greater responsibility in ensuring that data is only seen by staff who are authorized and require access to privileged information. That could mean creating tiered access and other protections like data redaction.

For example, an e-commerce website that handles credit card transactions, may require call centre staff to have access to the last four digits of a credit card number for verifying customers' identity when support call are received. Or an insurance claims website that requires claimants to submit their health identity number. The application displays the partially or fully-masked ID, enough to suggest that the data has been captured, but insufficient for a passerby to steal a glance.

Oracle's Data Redaction makes this possible, and with the latest release of Oracle Database 18c Express Edition, this technology is now acessible to developers for FREE! If you are new to Data Redaction, here's a simple recipe to get started!
