[edit] Confusing or unclear

This article would benefit from a clearer explanation about what a protection ring is and does. It assumes the reader knows what "one of two or more hierarchical levels or layers of privilege" means and why "rings were among the more revolutionary and visible concepts ..." The whole lead seems to step around defining what a ring is in simple terms, why it is significant, and how it is used. A very concise paragraph addressing some of the basics would be a great improvement to the lead section. JonHarder 13:57, 25 July 2006 (UTC)

  • After contributions by 68.144.178.242 and myself I hope this article has become more lucid. --OzJuggler 04:15, 5 August 2006 (UTC)

Maybe a more appropriate name for this subject would be "hierarchical states of privilege". I think that's the way it's called by academics. I think there also should be a comparison between this approach and Capability-based security with MMU support; as I leaned in my computer architecture and parallel computing classes, the first approach (the one described in this article) is an obsolete technology and provides both poor protection and poor performance, compared to the second approach. Unfortunly my reference text book is in italian, but I'm looking for some english ones.--BMF81 18:19, 27 August 2006 (UTC)

[edit] Ring -1?

I haven't found any articles here that even mention Ring -1 (hardware-mode virtualization). Perhaps this should be the place? --Frankie

There's not even a rundown of the ring levels and what they mean. This article would benefit from a table list rings and their properties, etc.
