Learn about web application security needed by software engineers every day.

Web App Security

The applications that we create for the web today have to face up to more security risks than ever before. It is extremely important that software developers enforce security best practices, such as how to add protection through HTTP headers, to protect against the myriad vulnerabilities that web applications are subject to. 
In this module, we’ll start by learning how to prevent fraudulent SSL certificates from being served to clients. Then, we’ll move on to learning how to defend against XSS attacks and clickjacking. 
In the latter half of the module, we’ll learn security practices related to HTTP cookies. We’ll also learn some tips related to security tradeoffs that we frequently make in our day-to-day work. Towards the end of the module, we’ll learn how to ward off DDoS attacks, which is crucial when our application scales. 
This module will demystify web security and help us stay on top of important security-related concerns in our web applications.

Web Application Security for the Everyday Software Engineer

## Decisions decisions!

Often times, we're faced with decisions that have a direct impact on the security of our applications, and the consequences of those decisions could be disastrous. This chapter aims to present a few scenarios you might be faced with and offer advice on how to handle each of them.

This is by no means an exhaustive list of security considerations you will have to make in your day to day as a software engineer, but rather an inspiration to keep security at the center of your focus by offering a few examples.
