Cybersecurity is the discipline of protecting computer systems against theft of information, damage of hardware, software, or data, and the disruption of services through denial-of-service attacks or the misdirection of services through botnets. The field of cybersecurity is rapidly growing in importance as the world increasingly relies on the Internet and wireless networks, computer systems, smart devices, and the many other devices that make up the Internet of Things.

This whitepaper deals with two specific aspects of cybersecurity: web application security and denial of service (DoS) attacks. Web applications, or web apps, are a type of computer program running on the client-server model where the client runs in a web browser. Denial of service attacks is a type of cyber-attack where the attacker tries to make a resource unavailable to the people who are trying to access it by disrupting the services of a host connected to the Internet.
