Set of assets and resources subject to a common security policy.\n\n3. A set of systems under common administrative and access control.\n\n4. A domain operating at a single security level (which includes a unique combination of classification, releasabilities, and dissemination controls) that implements a security policy and is administered by a single authority.\n\n5. An environment or context that includes a set of system resources and a set of system entities that have the right to access the resources as defined by a common security policy, security model, or security architecture. See Security Domain.\n\n6. The term domain refers to a part of the network that is administered by a single authority.\n\n7. See security domain.\n\n8. A set of subjects, their information objects, and a common security policy.\n\n9.
