Trusted Types: End to end injection safety at scale
Krzysztof Kotowicz, Mike Samuel at Global AppSec Tel Aviv 2019
18 years have passed since Cross-Site Scripting (XSS) became the single most common security problem in web applications. Since then, numerous efforts have been proposed to detect, fix or mitigate it, but these piecemeal efforts have not combined to make it easy to produce XSS-free code.
This talk explains how Google’s security team has achieved a high-level of safety against XSS and related problems by integrating tools to make it easier for developers to easier to produce secure software than vulnerable, and to bound the portion of a code base that could contribute to a vulnerability.
We will show how this works in practice and end with advice on how to achieve the same results on widely-used, open-source stacks and new browser mechanisms that will make it much easier to achieve high-levels of security with good developer experience.
