This presentation, given at the 2008 OMG real-time workshop discusses on-going research on the development on a secure DDS solution that can be practically deployed using today’s infrastructure. We will discuss issues such as:
(1) The definition of a SE Linux security policy suitable for DDS applications, including an identification of the Linux Objects and operations that must be enabled for DDS to work.
(2) The techniques available for deploying DDS on typical WAN environments, including networks that contain NATs.
(3) The definition of a pragmatic Role-Based Access Control model to protect DDS Topics and how to enforce the policies using the tools available in the standard PKI.
(4) The impact on performance and real-time predictability that these techniques introduce.
