Is Oracle Data Masking reversible?
After the processed data is received from the third party, the original data can be recovered. The Deterministic Encryption masking format supports reversible masking.
Which of the following are the techniques for Data Masking in Oracle?
Oracle notes that the Oracle Data Masking Pack includes the following features:
- Mask format libraries.
- Mask definitions.
- Masking techniques. Condition-based masking. Compound masking.
- Application masking templates import or export.
- Mask format library import or export.
- Masking script generation.
- Clone and Mask workflow.
What is masking data in Oracle?
Data masking presupposes that you have created an Application Data Model (ADM) with defined sensitive columns. Oracle Data Masking helps reduce this risk by irreversibly replacing the original sensitive data with fictitious data so that production data can be shared safely with non-production users.
What is Oracle data masking and subsetting?
Unlock the value of data without increasing risk, while also minimizing storage cost. Oracle Data Masking and Subsetting helps organizations achieve secure and cost-effective data provisioning for a variety of scenarios, including test, development, and partner environments.
What is the use of Oracle Database Vault?
Oracle Database Vault implements powerful security controls within Oracle Database 19c. These unique security controls restrict access to application data by privileged database users, reducing the risk of insider and outside threats and addressing common compliance requirements.
What is mutating in the trigger?
When something mutates, it is changing. Something that is changing is hard to analyze and to quantify. A mutating table error (ORA-04091) occurs when a row-level trigger tries to examine or change a table that is already undergoing change (via an INSERT, UPDATE, or DELETE statement).
What is Dbms_crypto?
DBMS_CRYPTO provides an interface to encrypt and decrypt stored data, and can be used in conjunction with PL/SQL programs running network communications. It provides support for several industry-standard encryption and hashing algorithms, including the Advanced Encryption Standard (AES) encryption algorithm.
How is data masking done?
Data masking is a data security technique in which a dataset is copied but with sensitive data obfuscated. This benign replica is then used instead of the authentic data for testing or training purposes.
How do I know if database Vault is enabled?
To check whether or not the Database Vault option is enabled in your database, run the following query as a privileged user: SELECT parameter, value FROM V$OPTION WHERE PARAMETER = ‘Oracle Database Vault’; The true/false value of the parameter will indicate whether or not it is enabled.

How does data masking work in Oracle Enterprise Manager?
Accessible through Oracle Enterprise Manager, Oracle Data Masking provides end-to-end secure automation for provisioning test databases from production in compliance with regulations.
Do you need a license to use data masking?
You must have the Oracle Data Masking and Subsetting Pack license to use data masking features. Performing masking on an 11.2.0.3 database that uses Database Plug-in 12.1.0.3 and higher requires that the database patch #16922826 is applied for masking to run successfully.
What is the patch number for masking in Oracle?
Performing masking on an 11.2.0.3 database that uses Database Plug-in 12.1.0.3 or higher requires that database patch # 16922826 be applied for masking to run successfully.
How is sensitive data masked in a database?
This ensures that all sensitive data is consistently masked across the entire organization. A masking definition defines a data masking operation to be implemented on one or more tables in a database. Masking definitions associate table columns with formats to use for masking the data.
