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

The traffic of a DOS attack comes from one source whereas that of a DDoS attack is generated from many sources. 

The traffic of a DOS attack goes to exactly one source whereas that of a DDoS attack goes to many sources. 

They are the same. The only difference is that DDoS attacks use less volumes of traffic. 

What is the difference between a DOS attack and a DDoS attack?
