So you’ve built an application and you haven’t thought about security… Don’t worry, this talk will bring you up to speed. We will explain what Cross-Site Scripting (XSS) attacks, Cross-Site Request Forgery (CSRF) attacks and clickjacking are and show you how to defend your application against them. We will also look at what HTTPS actually does and why we should always use it. To finish the talk off we will talk about other ways we can secure our application. By the end of this talk you will be able to apply this knowledge to your own applications to make sure they’re secure!
