Oracle Advanced Security Description
Oracle Advanced Security can be used to encrypt application tablespaces and prevent out-of band access to sensitive data. Redaction policies help to prevent sensitive data from being spread and ensure compliance with data protection regulations. Transparent Data Encryption prevents potential attackers from bypassing the database to read sensitive information directly from storage. This is done by enforcing data at rest encryption in the database layer. To protect sensitive data, you can encrypt individual data columns, entire tablesspaces, backups, and database exports. Data Redaction is an extension of TDE. It reduces the risk of data being exposed in applications by redacting sensitive information before it leaves the database. Redaction can be partial or complete to prevent large-scale extraction of sensitive information into spreadsheets and reports. Encryption is implemented at database kernel level, eliminating any need to make changes to applications.
