Re: [CDNi] Kathleen Moriarty's No Objection on draft-ietf-cdni-metadata-18: (with COMMENT)

[Kevin Ma J <[e-mail]>]

Hi Kathleen,

  I think that if an attacker could remove any of the ACL metadata, you could enable service in different regions, at different times, and to different end points, possibly in violation of the content owner's distribution rights (and possibly causing the content owner to incur excess delivery charges); but I would expect a premium content provider to have a DRM system outside the CDN delivery that enforces licensing restrictions and otherwise prevents hijacking the service as part of a criminal enterprise.  We will look at updating the threats in the next revision.

thanx!
