The Last XSS Defense Talk
Why are we still talking about Cross Site Scripting in 2020? Because it is painfully difficult to defend against XSS even to this day.
We will then look at advances in HTML sanitization on both the client and server and focus on sanitizers and defensive libraries that have stood the test of time in terms of maintenance and security. We'll also look at interesting design topics such as how HTML injection is still critical even in the face of rigorous XSS defense, how HTTPOnly cookies are largely ineffective, and how Trusted Types is making your favorite frameworks more secure.
This talk should help developers and security professionals alike build a focused and modern strategy to defend against XSS in modern applications.
