Re: [Ibnemo] [Sdn] Defining a Common Model for intent

[DIEGO LOPEZ GARCIA <[e-mail]>]

Hi,

May be we should start using different words for both meanings of "role", focused on the different mechanisms that would define them.

Functional roles would consist of the set of actions (functionality) available, according to the view that role has via the network abstraction available to it.

Access roles would consist of the the set of objects and actions that are available to that role when the security policies are applied, typically by means of RBAC.

Thinking about it, access role permissions should be applied on the objects and actions available to the functional roles the user has, so we are not talking about independent dimensions here, but of an ordered composition of the different kind of roles.

Be goode,

Hi Tianran,

Let Diego clarify, I might be introducing noise here. So I’d like to start exploring the infrastructure vs. Role intent ‘plane’.

Hi Pedro,

These examples are good starting point.
But I think the security you mentioned in the example is different from what Diego mentioned in other email.
I guess the security dimension Diego metioned is something like the Role Based Access Control.
That means, IMHO, a user can have the accessable/usable intent based on his role.
In your second example, the security is the more about function in firewall or router, like ACL.
