Posted by Unknown
SQL Database is quite vulnerable and it is quite a cumbersome task to keep it detached from these vulnerabilities. Preparing ourselves is all that we can do to fight against the odd. This is quite vigilant in case of ignorant enterprises that these face the biggest bang related to database damage. Here is a list of top vulnerabilities your database application may face. Keeping a note of these will help the organizations in developing some self defense.

Weak, blank, default login credentials

In order to maintain privacy and security of your SQL database, the login credentials needs to be highly secured. Thus, the enterprises that fail to understand these face hacking errors frequently.

SQL injections

Attackers keep a close eye on your database. A rare mistake may lead them to execute SQL injections as a form of Web-based attack. This allows them to gain access to your application functions and privileges.

More than the required group or user privileges

SQL database is sensitive to corruptions. Thus, it needs to have a limited or only required number of users to keep the database privacy intact. Even if the database is required to be used by multiple users, it is advised to assign different roles and limited or only required privileges to these users. In this way, you would also be able to manage the database in a much convenient manner.

Database applications usually comes with addon packages which most of the time remains unused by many organizations. In order to reduce attacks or corruptions, organizations are advised to look for packages that can disable these addons or may uninstall them. This surely helps in reducing zero day attacks.

Overflowing buffers

Over flowing buffers makes patching too complicated. Hackers use this most often to get an entry into your database files. This is a real cause of worry to the database vendors as they have already tried hard to improve upon glitches but seems like they need to give more attention to resolve this.

Unpatched databases

Enterprises or individual users are encouraged to maintain a highly secured environment for smooth running of the SQL database. They can make use of pre-installed security features as available with the SQL database application. However, in spite of maintaining all security, it is often seen that due to it being highly vulnerable, SQL database often goes corrupted.
