More people have access to the web than ever before. It incites that numerous organizations create web-based applications that clients can utilize online to interact with the organization. Inadequately composed code for web applications can be misused to increase unauthorized access to sensitive information and web servers.

A Web application is a program that is put away on a remote server and conveyed over the Internet through a browser interface. Web applications are generally created utilizing a mix of programming languages intended for use on the Internet. As a rule, web applications require less RAM to run and have a few advantages over desktop applications. Since they run inside internet browsers, engineers don’t have to create web applications for multiple platforms. Today, numerous browser games are designed to run as a web application, utilizing the browser as the client, rather than requiring local installation.

Most web applications are facilitated on open servers available through the Internet. It makes them vulnerable to attacks because of simple accessibility.
