It's also as best we can do, unless... If that's the best we can do then it's better to have no threat model at all than something that misleading, because all it's doing is giving a false sense of security. It doesn't even begin to capture semantics like: Alice will perform arbitrary scripted operations at the request of Mallory, directed against herself and/or Bob. a standard feature of every web browser out there. As a model against which to measure the security of an application or implementation, it's only slightly less useless than nothing at all. Peter.
