Software industry has grown to new heights in today's era. In recent times, the internet is driving almost every form of business. Web based Enterprise Resource Planning (ERP) system is a good example of the revolutionized IT world in recent ages. Now-a-days, websites are not only meant for marketing agenda or for publicity scenarios, but they have also evolved to gratify complete business solutions. Online payroll system, online shopping portals, online banking, and stock trading are not only used by companies, but are also sold as products.
Online applications have made the customers dependent on them. Therefore, the essential feature here is named as ‘SECURITY'. There is no doubt that security is of significant value for desktop based applications, also. However, when we discuss about web based applications, security factor increases exponentially. If a web based application is not able to protect important data, no one would use it.
The following are some examples of security imperfection in an application:
Online banking is insecure if customer transaction details can be edited even by bank employees
Web shopping portals have no security if customer's credit card details are not ciphered
An online account is insecure if any SQL query gains actual password of the user
