The objective of this article is to give you an insight on various areas that a design architect should focus on while designing a web application to make more secured. This article discusses almost all types of vulnerability that can be exploited by the hacker and the counter measure to avoid the same. Effective way of analyzing the various security issues on a web application by decomposing the problem domain into various areas of focus. I have discussed the same in detail below. If you follow this approach, you get your focus on the key design and implementation choices that affect your application's security. Input validation Identi...
