There are more vulnerabilities than ever when creating applications for the web, so it is extremely important that software developers enforce security best practices such as, how to add protection through HTTP headers.

In this course, you will start off by learning how to prevent fraudulent SSL certificates from being served to clients, before moving on to how to defend against XSS attacks and clickjacking. 

In the latter half of the course, you’ll learn security practices related to HTTP cookies, and tips around security tradeoffs that you’ll make in your day-to-day work. Towards the end, you’ll learn how to ward off DDoS attacks, which is crucial when your application scales.

This course will demystify web security, and help you stay on top of important security-related concerns in your web apps.

Web Application Security for the Everyday Software Engineer

# Popular web applications are prone to attack
As soon as your web application grows and becomes more popular, it is bound to attract some unsavory foes. One of the most common attacks you're likely to face is a **Distributed Denial of Service** (DDoS), where a network of machines is trying to infiltrate your webservers.

# Chapter walkthrough
In this chapter, we will look at how DDoS attacks work and will have a look at some of the ways you can protect yourself from them.
