MASTER IN WEB APPLICATION HACKING

Web application development is the creation of application programs that reside on remote servers and are delivered to the user’s device over the Internet. … Front-end development for web applications is accomplished through client-side programming. Client refers to a computer application such as a web browser.

Even though PHP is, by a wide margin, the most used server side programming language, it is amusing that when it comes to websites that attract high traffic, Java and Javascript are the clear winners. The web application requires a web server to manage requests from the client, an application server to perform the tasks requested, and, sometimes, a database to store the information. … User triggers a request to the web server over the Internet, either through a web browser or the application’s user interface.

Millions of businesses use the Internet as a cost-effective communications channel. It lets them exchange information with their target market and make fast, secure transactions. However, effective engagement is only possible when the business is able to capture and store all the necessary data, and have a means of processing this information and presenting the results to the user.

Web applications use a combination of server-side scripts (PHP and ASP) to handle the storage and retrieval of the information, and client-side scripts (JavaScript and HTML) to present information to users. This allows users to interact with the company using online forms, content management systems, shopping carts and more. In addition, the applications allow employees to create documents, share information, collaborate on projects, and work on common documents regardless of location or device.
