Definitions
Definition 1 - A community of interest governed by authorities
An Information Security Domain is a bounded and coherent system. It is composed of entities that constitute a community of interest, identities, and/or resources. It is governed by common authorities that issue policies. These policies prescribe if and how entities are authorized to perform which operations on which resources.
The term is loosely used to designate diverse combinations of micro- and macro-systems as long as they are regarded as a whole, thus context is paramount for clarity.
