MULTI-DOMAIN ACCESS CONTROL POLICY IN WIRELESS CLASSIFIED ENVIRONMENTS USING STEGANOGRAPHY.

Security policies are critical aspects of secure computer systems. For wireless classified environments enforcing multiple concurrent policies across multiple domains, the design of correct implementation mechanisms is a challenging and difficult task. In order to simplify this task, our research work applies an additional layer of defensive mechanism using steganography to secure data in our multi-domain access control model. In this model, multiple independent policies are specified that describe relationships between sets of entities in the classified environment. These multiple policies are then integrated into a single enclave system by applying an inter-enclave multi-policy classification paradigm for information access using steganography. Our methodology is structured to assist system security managers in reducing the complexity of policy development and implementation, and is applicable to a spectrum of wireless classified environments.
