There is a project at Columbia that is exploring using financial market based techniques to control access to resources in a network. (I'll leave the exact details out, see http://www.cs.columbia.edu/dcc/MarketNet ) The idea is to control resources with currency in an involved system including a banking infrastructure. A basic extension to that idea would be to use streaming currency to continue using resources on a system. The main idea behind this is to use provably secure market-based primitives to minimize denial of service (and other) attacks. The project is modelled as network domains but in this discussion we can assume a domain to be a VM to see how we can identify and control attacks on a domain. I will probably go into more details if there is more interest on this list. Essentially, I'm trying to break the domain into two portions: (1) How do you identify an attack in a runtime system and macro controls (MarketNet is a possible solution in this sphere) (2) The details of the control implementation (as Doug and the rest have been so graciously contributing to the list) Cheerios! - Rahul Merwah Get Your Private, Free Email at http://www.hotmail.com ---------------------------------------------------------------------------- To unsubscribe (or other requests) mailto:majordomo@media.mit.edu List archives, FAQ, member list, etc. http://gee.cs.oswego.edu/dl/javares/
