Dynamic Data Masking

If you love reading blogs, database news threads, tweets or listening to podcasts of best data handlers of all times, then you must have heard about data masking or data obfuscation. It’s the process of hiding original data using random data or characteristics. It involve crafting of analogous but inauthentic data version of an organization’s data for user training and software testing purposes.  Most likely, you have also heard about Dynamic Data Masking (DDM) which delivers high-throughput as well as low-latency performance incapable of impacting user experience. This article outlines how dynamic data masking works.


How it works

Dynamic Data Masking works in a unification with database application in real-time for the unauthorized users not to see …

Usually, unlike stateful-packet filtering firewalls for dynamic data masking, application-layer firewalls are always aware of certain applications, for instance the Web, SQL, and e-mail. Also, these multi-talented firewalls prohibit direct connections from the Internet to your servers by assuming the proxy role between the applications you serve (Web, E-mail, FTP, etc.) to the rest of the wired world.

Decisions based on protocol Enterprise networks can no longer allow or deny traffic based on protocol alone. Now that exploits through common and necessary protocols (HTTP, SMTP, etc…) have become frequent. They must employ firewalls for dynamic data masking capable of inspecting protocol data in the TCP header.

Application-layer firewalls usually act as both client and server, by ‘proxying’ the data between …

Dynamic data activity monitoring, usually abbreviated as DAM refers to a database security technology purposed for monitoring and analyzing database activity that operate independent of the database management system (DBMS) and does not depend on any form of native (DBMS-resident) auditing or native logs such as trace or transaction logs.

Dynamic data masking

Database activity monitors captures and records database events, which at a minimum includes all Structured Query Language (SQL) activity, in near real-time, including database administrator activity, across multiple database platforms and generates alerts on policy violations. What does this imply? DAM is the only tool that sees everything that takes place within your database. This means every action by an application, user or administrator can be collected, analyzed and can …

File activity monitoring is similar to database activity monitoring in many respects. For instance, a simple vivid example is that in both cases, you discover the sensitive data on your servers and configure policies to create rules about data access and actions to be taken when rules are met.

File activity monitoring may include the following capabilities:

  • Discovery to inventory files and metadata.
  • Classification to crawl through the files to look for potentially sensitive data, such as credit card information or personally identifiable information.
  • Monitoring- which can be used without discovery and classification to monitor access to files based on policy rules, audit and alert on inappropriate access, or even block access to the files to prevent data leakage.

Usually, hackers know what they want and where to find it. Crucial dynamic data centres such as file servers are among the most targeted sources of your intellectual property, financial information, deal data, or PII. Most cyber-attacks have become increasingly sophisticated, leveraging multiple tactics and tools, all with one goal: getting in. The role of file firewall for dynamic data masking is to protect sensitive unstructured data where it resides, so that you can prevent data breaches, along with their resulting exposure, costs and brand damage.

Thus file firewall prevent your files from becoming an easy target for internal and external threats. Moving forward you can immediately respond to suspicious file access activity by generating notifications, or in certain situations, …

The phrase dynamic data breach notification is rather ambiguous, especially when details such as personal information are introduced into the equation. In general, however, a dynamic data security breach may take place when there is unauthorized access to sensitive Personally Identifiable Information (PII) that could compromise the confidentiality or integrity of data. Dynamic data breach notification involves mandating that the company holding the PII notify those whose PII was compromised.

Just a few specific sectors of the private-sector economy are currently required by federal law to notify consumers when a dynamic data breach may have compromised their personal information, or PII. These include certain financial institutions covered by the Gramm-Leach Bliley Act and certain health care entities covered by the …

Oracle databases have been in existence for quite a while now. To be precise, Oracle released their 9i (9.0.1) version about 2 years ago. Many companies are still using the 8i (8.1.x), 8 (8.0.x) and 7.x database versions. For the most part, everything that is available in a lower version will be available in a higher version as well.

There are a few minor exceptions, but the Oracle databases tend to be backwards compatible. When Oracle releases a new version, their documentation contains a list of all the features new to that version. So it is worthwhile for the Database Administrator to read this documentation to discover what is new in the dynamic data masking database.

For each and every database, there must be at least one database administrator abbreviated as DBA to perform administration duties on it. Since an Oracle dynamic data system may be large and can have multiple users, often this is not a single person’s job. In similar cases, there is a group of Dynamic Data Administrators who share this responsibility.

Dynamic Data Masking

A database administrator’s duties can include the following tasks:

  • Installing and upgrading the Oracle server and application tools
  • Allocating system storage and planning future storage requirements for the database system
  • Creating primary database storage structures (table spaces) after application developers have designed a certain application
  • Creating primary objects (tables, views, indexes) once application developers have designed an application
  • Modifying the database

Most different database service providers provide database as a service that is further divided into major three categories. There are rational database, non-rational database and operating virtual machine loaded with local database software like SQL.

Database Service providers vary from each other depending on the quality and sort of services being provided. There are certain parameters that can be used to select the best service that will suit your company best. This is not limited to a certain company; these parameters can help in deciding the best service provider depending upon the requirements of any company.

Parameters of Database Service

This article seeks to explore the dynamic data masking  as service paradigm and the challenges introduced by that. Today, efficient data processing is a fundamental and vital issue for almost every scientific, academic, or business organization. Therefore the organizations end up installing and managing database management systems to satisfy different data processing needs.


Although it is possible to purchase the necessary dynamic data masking software, hardware, deploy database products, establish network connectivity, and hire the professional people who run the system, as a traditional solution, this solution has been getting increasingly expensive and impractical as the database systems and problems become larger and more complicated. As described above, the traditional solution entails different costs. It might be arguable that …
