Oracle database management tracks its computers data storage with the help of information stored in the system or tablespace. The system or tablespace contains the data dictionary and often (by default) indexes and clusters. A data dictionary consists of a special collection of tables that contains information about all user-objects in the database.

The oracle RDBMS also supports “locally managed” tablespaces that store space management information in bitmaps in their own headers rather than in the tablespace or system (as happens with the default “dictionary-managed” tablespace).      orlOracle has also introduced the tablespace or system, which contains some of the tables formerly stored in the tablespace (system), along with objects for other tools such as OEM, which previously required its own …

DataSunrise data masking restricts sensitive data within a database from exposure to non-privileged users. This prevention of unauthorized access to sensitive data is done by creating a structurally similar but inauthentic data to provide it for some external services. This is to protect the sensitive data from being exposed to the wrong people, it maintain the security of the data within the database.

In proxy mode DataSunrise is able to monitor SQL statements that database clients send to a database and hide original data with random or predefined data. DataSunrise supports data masking in proxy mode only. It evaluates each SQL statement by using the list of rules in order or rule priority. DataSunrise then executes the first rule …

This is the process of obscuring or masking specific data within a database to prevent it from security breaches. This masking enables the securing of the sensitive data. Such sensitive data include information like a customers’ identification number which need to be protected from unauthorized personnel.

Oracle Data masking enables organizations to comply with data privacy and protection mandates that restrict the use and sharing of private, sensitive or personally identifiable information. With oracle data masking sensitive information can be replaced with realistic values, allowing production data to be safely used for the development, sharing or testing with out-sourcing partners or off-shore teams for other non-production purposes.

Advantages of Oracle Database Masking.

Database software platforms typically integrate basic audit capabilities but they often suffer from multiple weaknesses that limit or preclude deployment. This articles explains some of the major factors that would prevent the deployment of data audit in many business organizations as highlighted below:


1.    Lack of User Accountability

When a user uses a web application to access a database, the native audit mechanism have no awareness of specific user identities. Because of this user activity is associated with the web application account name. Therefore, when native audit logs reveal fraudulent database transactions, there is no link to the responsible user hence one can use someone else account to do wrong and not be found.

2.    Performance Degradation

Native database audit …
