At sign-in, the browser generates a private key and binds it to the session. When #cookies expire or are missing, the browser must contact a server-designated refresh endpoint and present proof of key ownership to obtain fresh cookies. #security

Based on the @w3c workshop "Secure the Web Forward” and thanks to work taking place in the W3C Security Web Application Guidelines (SWAG) #CommunityGroup, we are happy to release 6 videos that address the complexities of Content Security Policy and Trusted Types, by introducing open-source tooling that reduce uncertainty and complexity of configuring web #security mitigations against XSS.

How to protect your Web applications from XSS

The W3C SWAG (Security Web Application Guidelines) Community Group, launched in June 2024, aims to simplify security features in web app development. SWAG's mission is to enhance web app security by creating best practices for developers and fostering collaboration. A key output includes videos on configuring CSP and Trusted Types, which mitigate XSS. Based on Google’s adoption experience, these resources offer tools to help developers securely configure these protections with minimal effort.
