Database Firewall helps in securing crucial information within an organization, provided the organization’s aim is to prosper. With highly confidential data comes the great responsibility of protecting it. Hence having a database firewall should be the fast option for any organization wishing to be successful in its undertakings.

For there will always be someone with unpleasant motives targeting the organizations data intending to misuse it. With the growth of technology and the sophistication of hackers it is close to impossible if not impossible for an organization to survive without the use of a database firewall to protect their data at all time.

Reasons for which Database can be hacked

There are very many different reasons for the hacking of organizations databases, but some of the common reasons are:

  • Used by your competitors to derail the progress of your business.
  • Used by random hackers to get sensitive information within the database so that they can be able to blackmail you.
  • While some maniac hackers just do it for the fun.

How Database Firewall Protects Databases from Threats

A set of specified, customizable security examinations guidelines are included in the Database Firewalls. These set of guidelines recognize the potential attacks based on the past records. Records of these threats from the past incidents are saved as ‘signatures’.

The SQL queries are evaluated with these signatures to know the potential of the threats. The signatures are regularly updated so as to block the latest threats hitting the database. Some Database Firewalls are designed to compare the parameters such as application’s type, IP address, location, time etc. with the already existing information

All the attacks or potential threats may not be recognized by the Database Firewall. Database firewall may not have a signature record of all threats that is why it comes with two lists, or you can say filters

  1. White List
  2. Black Lists

White List

The White list contains the approved SQL queries/commands/statements that are safe for the database. All the input SQL statements are evaluate with this list and only those SQL statements are allowed to enter the system that are already there in the white list

Black List

This is the list of potential threats. If any SQL statement is found present in the Black List, that query/statement is blocked.

What Database Firewall Security Does

  1. Delete the unused accounts and prevent the shared accounts for accessing the database.
  2. Can encrypt your sensitive content with Data Masking techniques
  3. Provide different accessibility authorities to different user such as one user can “Read only” and others can “Edit/Insert/Delete”. This way the owner can control the access of some users to certain parts.
  4. Can be updated via authorized applications. Individual users don’t have to update it from their end.

From the information above it is well evident the benefits of an organization having a Database Firewall to protect their data. There are numerous database firewall suits which are able to ensure the protection of an organizations database. Such suits include: Oracle Database Firewall, Datasunrise Database Firewall. GreenSQL Database Firewall, Imperva Database Firewall among others.
