Web Database Security

Databases connect to internet through web-based application always at risk and threat. A usual style of attack on a database is SQL injection attack. All databases uses Structured Query Language and all interface language communicate with databases with this language. All interface languages use this language to perform database queries and actions. So the queries can be accessible from a web based application for example in the form area of a website. Instead of your name you insert a SQL query and now if the database is not secured properly it can give you data in return of your query with any password or login.

You also can put some strange pieces of faulty or mal formed code to perform data bases strange results. Faulty SQL check and bounce check must be performed by database programmer. Poorly written web application allows easy access to data in database if it is not constructed well. So the databases must be fairly secured.

What we can do to secure our databases?There are few things and most of database applications allow you to do these things

1. PermissionsAbsolutely perform restriction on database. Like if a person needs to see client name and address but if he did not need to see financial information of client. It must be restricted to see by him.

2. Restricted ViewsApplication must be design on restricted views and web-application must be based on a proper user access and views policy. Restriction of views can generate good results because a user only can see data what he required from application. Limited access of data could safe a web application from many problems in future. Restricted view can be a constraint user interface which only allows user to access data of his/her need.

3. Data PartitioningData Partitioning is very useful to secure your data. Partitioning of data have a simple concept like if we have two kind of information of a user saving in database one is his personal information and other is his financial information. We can simply divide information into two databases. Simply separate personal information and financial information can give us a great security against user privilege problems. Even we can perform physically data partitioning to divide a database in to two databases and dive them in two physical drives.

4. Protection of ConnectionAlways use data encryption to protect data when web server and database server communicates. Database programmer can make an application between database server and web application and connection between web server and data base server can perform by that application, a secure and encrypted database connection is requirement for a good safe online web application.

5. Layers of AuthenticationsDatabase on web require many layers of authentication and protection from internet users and even inside users if data is sensitive enough. We can install a firewall between application and database.

6. Database AuditAudit of database is very important and normally neglected by database users and administrators; very critical issue is to audit a database with proper time line and frequency. Audit all transaction and check them properly. If there is a problem on application illegal access on database, that can be trace with a proper audit of database.

7. Database BackupMost important part of a database is backup of its. Because you can restore operating system, you can restore application you can make database again but you can't make the data again. So keep backup you database regularly.
