Poorly written code for web applications can be exploited to gain unauthorized access to sensitive data and web servers. In this tutorial you will learn how to hack websites, and we will introduce you to web application hacking techniques and the counter measures you can put in place to protect against such attacks. A web application aka website is an application based on the client-server model. The server provides the database access and the business logic.
It is hosted on a web server. The client application runs on the client web browser. Web applications are usually written in languages such as Java, C , and VB.

DOD has been pleased with its program, continually expanding it to authorize hackers to pursue new targets, most recently in May opening it up to all publicly accessible DOD information systems , industrial control systems, the internet of things and more.
Critics of bug bounty programs , however, contend that they can undermine security by placing an emphasis on lesser bugs that organizations become too reliant upon in their overall security setups, among other potential ill side effects.
