[x3d-public] [X3D-Public] X3D Security capabilities and needs

Being sort of lazy since I could read every spec......

But it seems that many applications can be attacked by attacking the
applications implementation of specifications [Open Geospatial Consortium,
Web3D, every XML/DOM type of spec,....].

So, is there a discussion available of general web application security for

Example: Can you point me to the Data Flow diagrams for Xj3dEdit?

Christoph, again thanks for your feedback a few weeks ago.

I've integrated numerous points (including yours) and added them to X3D
Resources - Security.

Continued scrutiny, issues and improvements continue to be welcome in this
important area.


The .x3d encoding is XML based, which means that the full power of Web
Security can be applied to X3D Graphics models.

     X3D Security Examples demonstrate conversions for XML Encryption and
XML Signature (digital authentication)
     X3D Security Examples README describes technical detail about how all
this works.

X3D capabilities for model security, existing and emerging:

     Multiple forms of validation are available to prevent unwanted
insertions of malicious content in X3D models.
     Strongly typed metadata can be inserted in any X3D model. Interchange
conventions are expected to emerge with growing usage.
     Security mechanisms can be applied to high levels of detail (LOD),
allowing authors to protect intellectual property at high resolution for
authorized users while still rendering simple unrestricted models for other
     XML Security compatibility, specifically the XML Encryption and XML
Digital Signature (authentication) Recommendations.
     XML Security mechanisms can be applied to entire scenes in .x3d files
(XML documents) or scene subgraphs within an .x3d file (XML fragments).
     XML Security mechanisms allow declaration of relevant encryption
algorithms in the envelope header.
     XML Security software is broadly available and usable by international
partners in any context, including Web commerce.
     Data-centric security is independent of network-transport security.
     W3C Efficient XML Interchange (EXI) Working Group is ensuring that
XML-based data compression can be used compatibly with XML Security.
     W3C Security Interest Group serves as a forum for discussion about
improving standards and implementations to advance the security of the Web.
     Most of these capabilities are demonstrated and formalized already.
Some are working-group efforts in progress. This emerging combination of
capabilities can thus be considered low risk, with high probability of full
convergence eventually occurring.

X3D player and tool support for security:

     X3D-Edit authoring tool.
     Advanced developers can use native XML tools. Open security by design
provided by XML Security is the strongest approach for international use.
     Proprietary encryption tools are occasionally available. User beware:
security through obscurity is not strong security.
     Required support for secure url addresses using https and ssl/tls
protocols are likely to be included in X3D versions 3.4 and 4.0.
     TODO: better built-in support is needed by X3D players and tools.

Interested? The Web3D Consortium X3D Working Group participates in the W3C
Security Activity to continue taking advantage of ongoing developments.
Member participation is welcome.
