Towards achieving cross domain information sharing in a SOA-enabled environment using MILS and MLS technologies

Many Programs of Record are using Service Oriented Architecture (SOA) approaches and supporting technologies to realize net-centricity requirements. Furthermore, emerging solutions offer data sharing across adjacent security enclaves for these programs, including Cross Domain Joint Battlespace Infosphere (XJBI) by AFRL, Cross Domain Web Services Gateway by DISA, and the Cross Domain Collaborative Information Environment and Collaboration Gateway by the Joint Forces Command (JFCOM). While these solutions address the specific environment, it has proved insufficient to meet all the use cases of net-centricity requirements. This paper describes approaches that supplement the existing solutions by incorporating existing and emerging multi-domain technologies, primarily Multiple Independent Levels of Security (MILS) and Multi-Level Security (MLS).
