Notes from 20080509 Teleconf
Attending: Jim, Brian, Mary, Paul, Drummond, Markus, Valery, Bruce, David, Tony, others I missed?
Agenda:
Notes:
- Looking at Policy-Entities.pdf
- Paul intended this to be a simple proposal and to show how it might help Parity do something they're working on.
- Tony: Bootstrap issue
- what's the policy on the policy
- need to make sure we can make policy statements
- what's the policy on the policy
- David: Where are the enforcement points?
- Jim: The CP must ensure (whether it has to do it, or the backing store does it)
- Paul: Agree
- David: If there's an external enforcement engine, I have other questions.
- Paul: There is the option of fronting
- David: Can the accessing Entity be in another CP?
- example: cp entities are entries in a database, but the authenticating identity does not exist in the context.
- Subject ID must come from somewhere
- CP can derive it from authN materials
- an authenticated user can be mapped to a subject id
- CP can derive it from authN materials
- AuthZ Subject IDs need to be flexible
- need to be able to specify roles, groups
- example: allow anyone from my facebook friends to do X
- Drummond suggests using UDI for AuthZ subjectID
- need to be able to specify roles, groups
- What about referential integrity?
- The CP must be required to ensure authZ subjectID is not re-assignable
- In some cases, (i.e. when the authZID is provided by another ctx), it's up to the other ctx.
- The CP must be required to ensure authZ subjectID is not re-assignable
- No contention regarding the notion of using an access control policy entity
- Next meeting topics:
- How to perform interrogations like "can bob edit alice's phone number?"
- David has some others surrounding the policy object.
