Rationale behind Installing a Firewall

If you have some highly private data at your disposal, you should know that it is an important duty to protect it from exposure.

If you still think that you don’t need a database firewall, give it another thought. Most likely there is someone curious to know your company’s sensitive information to misuse it.

Reasons you should know how/why your databases can be hacked:

  • Your opponents want to ruin your business.
  • Strangers are going to steal your data to sell it on the black market or blackmail you.
  • Several hackers violate databases just for fun.

Database firewalls will make you feel convinced about your data security. It provides effective pro-active protection by continuously watching the database traffic, data breaches, preventing SQL injections and abuse of privilege. In other words, Database firewall protects your data from all types of external and internal threats.

How firewalls guard your databases?

Database firewalls mostly depend on “signature analysis” method. These “signatures” resemble SQL statement series known as typically used by hackers. A firewall stops incoming SQL doubt and compares its code with known signatures.

Signature lists are being continually updated to allow firewalls to defend against the latest threats striking databases. Some database firewalls can collect information on client application type, location, IP address, time, etc. and analyze it while performing signature analysis.

Of course, signature-based systems can recognize only already-known threats — the ones they know about. That’s why firewall developers employ another, but quite alike, technology as well.
