flow controlnounMWEA security control mechanism — specifically a set of policies and their enforcement — that governs *where* information is permitted to travel within a system or between interconnected systems, as distinct from *who* is permitted to access it. It "regulates where information can travel within a system and between systems (in contrast to who is allowed to access the information) and without regard to subsequent accesses to that information." Organizations employ flow control policies and enforcement mechanisms to control information movement between designated sources and destinations; enforcement is based on characteristics of the information and/or the information path, and is implemented in boundary protection devices — such as firewalls, gateways, and routers — using rule sets, packet-filtering on header information, or message-filtering on content. In practice it covers a wide range of restrictions: blocking external traffic that claims internal origin, preventing export-controlled data from being transmitted in the clear, restricting web requests to those from an authorized proxy, and limiting inter-organizational transfers based on data structures and content.verified
flow control restrictions includenounMWEThe specific policy-derived constraints — such as blocking spoofed traffic, preventing unencrypted transmission of export-controlled data, or limiting cross-organizational data transfers by content type — that an organization imposes under an information flow control regime. They are distinguished from access control (which governs *who* may reach information) by governing instead *where* information may travel within or between systems, irrespective of who subsequently accesses it. In practice, security architects and compliance teams invoke the concept when specifying, auditing, or implementing the enforceable rules that make an information flow control policy (e.g., NIST AC-4) operational.verified
Flow DiagramnounMWEa diagram of the sequence of operations in a computer program or an accounting systemverified
flow of CUInounMWEThe movement of Controlled Unclassified Information (CUI) as it transits within a system and between systems — distinct from the question of *who* may access that information — governed by policy-based controls at enforcement points. Organizations use information flow control policies and enforcement mechanisms to regulate movement between designated sources and destinations (e.g., networks, individuals, and devices) within systems and between interconnected systems. Enforcement occurs in boundary protection devices such as gateways, routers, guards, encrypted tunnels, and firewalls, which employ rule sets or configuration settings that restrict services, filter packets based on header information, or filter messages based on content. Identifying and controlling how CUI flows throughout an organization determines, in many ways, how all other security controls in a framework such as NIST SP 800-171 are implemented.verified
