Approach to object security in Distributed SOM |

We briefly review the IBM System Object Model (SOM, incorporated in
SOMobjects™) and Distributed SOM (DSOM). We then describe
the base
DSOM security architecture characterized by the presence of the Object
Security Service (OSS) framework in the DSOM run-time environment.
Depending on its implementation, this framework can be wrapped around
procedural security service providers, thus taking advantage of
existing security mechanisms. Subsequently we elaborate on the OSS
elements for authentication and authorization and how they relate to
the DSOM Object Request Broker (ORB™) on the one hand,
and to the
client and server applications on the other hand. We discuss
the DSOM approach to object access control and present a novel
method for enforcing it.
