Web applications provide vast category of functionalities and usefulness. As more and more sensitive data is available over the internet hackers are becoming more interested in such data revealing which can cause massive damage. SQL injection is one of such attacks. This attack can be used to infiltrate the database of any web application that may lead to alteration of database or disclosing important information. Cross site scripting is one more attack in which attacker obfuscates the input given to the web application that may lead to changes in view of the web page. Three tier web applications can be categorized statically and dynamically for detecting and preventing these types of attacks. Mapping model in which requests are mapped on queries can be used effectively to detect such kind of attacks and prevention logic can be applied.
