Security Activity

Security at W3C

Web Security is a collaborative effort across the Web ecosystem; W3C coordinates some of that work in its Security Activity, within the Technology & Society Domain. Among the work we are doing to help secure Web applications and Web usage:

Web Cryptography Working Group

Motivated by the emergence of more complex protocols executed between Web applications, the WebCrypto group is defining an API to expose trusted cryptographic primitives from the browser. protocols. API features will include message confidentiality and authentication services, as building blocks for improved Web security.

Draft: Web Cryptography API (Last Call published 25 March, 2014)

Web Application Security

WebAppSec is developing the Content Security Policy and CSP Level 2; Cross-Origin Resource Sharing; UI Security; Subresource Integrity and Mixed Content Recommendations. This work aims to enable secure mash-ups, address click-jacking, and to create a more robust Web security environment through light-weight policy expression that meshes with HTML5's built-in security policies.

XML Security

XMLSec produced three W3C Recommendations: a stable interim set of 1.1 specifications. The XML Signature 1.1 and XML Encryption 1.1 specifications clarify and enhance the previous specifications without introducing breaking changes. XML Signature Properties outlines the syntax and processing rules and an associated namespace for properties to be used in XML Signatures.

Web Security Interest Group

The Web Security Interest Group serves as a forum for discussion about improving standards and implementations to advance the security of the Web.

Related Work: Privacy

The Privacy Interest Group watches for ongoing privacy issues affecting the Web, investigates potential areas for new privacy work, and provides guidelines and advice for addressing privacy in standards development.
