| Information flow control regulates where information is allowed to travel within an information system and between information systems (as opposed to who is allowed to access the information) and without explicit regard to subsequent accesses to that information.
Specific examples of flow control enforcement can be found in boundary protection devices (e.g., proxies, application gateways, guards, cross domain systems) employing rule sets or establish configuration settings restricting information system services, provide a packet-filtering capability based on header information, or message-filtering capability based on content (e.g., using key word searches or document characteristics).
Attribution, (e.g., the ability to attribute actions to individuals), processes or systems, is a critical component of a security concept of operations.
The ability to identify source and destination points for information flowing in an information system, allows forensic reconstruction of events when required, and increases policy compliance by attributing policy violations to specific organizations/individuals.
This requirement is specific to network devices designed to perform information flow control. This requirement is NA for databases. |
