As the Web Platform around HTML5 emerges as a platform for sophisticated application development, security properties of both implementations and specifications become critical. This group provides a forum for technology designers, implementors, and other intersted parties to work toward improving specifications and implementations to advance security of the Web overall.

The group is, in particular, focused on the security properties of HTML5 and related APIs and technologies.


As an Interest Group, this group has no formal deliverables. The group may propose additional standards work to the W3C, and may publish Interest Group Notes as needed. Examples of possible Interest Group Notes include best practice guidance and design considerations.
