Microsoft releases Web Sandbox

Software giant Microsoft has made source code for its Live Labs Web Sandbox project for securing Web content through isolation available via open source under the Apache License 2.0s.

Web Sandbox features technology for mashing up code while maintaining process isolation, quality of service protection, and security. It is intended to address a problem in which Web gadgets, mashup components, advertisements, and other third-party content on Web sites either will run full trust alongside content or are isolated inside of IFrames. This results in many Web applications being intrinsically insecure with unpredictable service quality.

Microsoft has open-sourced the Web Sandbox framework and is partnering with industry leaders to evolve Web Sandbox into an industry-wide solution.

Microsoft is looking for developers to experiment with Web Sandbox. Web Sandbox builds upon Microsoft's experience with DHTML, Windows, Windows Live Web-based gadgets, and the Microsoft BrowserShield project, which leverages JavaScript virtualization through rewriting.

Although Microsoft is using an Apache license for the project, it is not sponsored or endorsed by the Apache Software Foundation. The company last year became a sponsor of the foundation.
