Integrated content-based information security for future military systems

Future military operations require versatile and integrated mechanisms for enforcement of the security policies in all three domains of information protection: confidentiality, integrity and availability. We discuss challenges and use cases related to enforcement of integrity and availability policies in federated mission environments and we demonstrate how the concept of Content-based Protection and Release (CPR) can be extended to support such policies. Furthermore, we present an approach to cross-layer enforcement of the CPR policies and introduce a proof-of-concept implementation of the CPR enforcement mechanisms in a software-defined networking environment.
