[Model-t] Dependable, secure, flexible and extensible

[Robin Wilton <[e-mail]>]

Hi Russ,

Thanks for spotting this. I expect Ekr will probably have some thoughts about whether this meaningfully changes the scope of what model-t is considering, as (to my recollection) most of the comments about scope, in Singapore, came from him.

Without wanting to second-guess that, my thought is to wonder whether “dependable, secure, flexible and extensible” actually reduce to the standard security triad of confidentiality, integrity and availability. "Dependable, flexible and extensible" might legitimately be considered as “availability” pre-requisites, especially in the sense that a system that is insufficietly flexible or extensible becomes “unavailable" if it cannot respond to changing circumstances or requirements.

Does that help?

Yrs.,
Robin

In Section 3, the authors are talking about the properties that they want from the distributed information utility:  dependable, secure, flexible, and extensible.  Reading between the lines, they seem to be saying that a threat is something that prevents achieving one of these properties.
