| When data is exchanged between information systems, the security attributes associated with the data needs to be maintained.
Security attributes are an abstraction representing the basic properties or characteristics of an entity with respect to safeguarding information; typically associated with internal data structures (e.g., records, buffers, files) within the operating system and used to enable the implementation of access control and flow control policies, reflect special dissemination, handling or distribution instructions, or support other aspects of the information security policy.
Security attributes may be explicitly or implicitly associated with the information contained within the information system. |
