PURR is built on HUBzero®, and as such benefits from the Joomla! security patching practiced by the HUBzero team as well as the extensive security auditing of HUBzero. As PURR uses only the native HUBzero security, authentication, and authorization mechanisms, it is probably safe to say that PURR is as secure as HUBzero itself. That being said, PURR and HUBzero were built to foster scientific collaboration, not to support multi-level compartmentalized information (for example, a system that can hold public, CONFIDENTIAL, and SECRET materials simultaneously) — but very few multi-level compartmentalized secure systems have ever been built.
How secure is PURR?
