I created this presentation for two purposes: On the one hand it can be used as an ultra-compact introduction to Web Application Security. It is best combined with a live-demo, e.g. using my own Juice Shop vulnerable webapp.
On the other hand it turns out to be useful for refresher sessions, e.g. with former participants of my Web Application Security Training Workshop. Here I usually just walk through the presentation and afterwards let the participants have a hands-on-hacking-session on the Juice Shop for reinforcing their knowledge.
