designated personnelnounMWEA collective noun for individuals or job roles within an organization that have been formally assigned—by policy, regulation, or organizational decision—specific security, privacy, or compliance responsibilities, and to whom corresponding obligations (such as receiving policy disseminations, executing controls, or leading incident response) are explicitly directed. Authority documents such as the DHS 4300A Sensitive Systems policy use the expression to introduce the roster of roles that "play a major role in the planning and implementation of information security requirements," while NIST SP 800-53 control language recurrently names "organization-defined personnel or roles" as the recipients of policy documents and procedural dissemination. Across frameworks the expression functions as a placeholder that an organization fills in during tailoring—naming the CISOs, privacy officers, system owners, or other accountable parties—rather than denoting a single fixed role; the underlying concept is that clearly assigning security responsibility to specific individuals or roles ensures accountability and helps prevent lapses in security management.GroupInternal
designated policy enforcement pointnounMWEAn architecturally assigned location — a specific node, mechanism, or boundary control — that an organization has formally chosen to serve as the place where information-flow or access-control policies are actively applied, typically at the juncture between systems of differing security domains or trust levels. The modifier *designated* signals intentional placement by policy decision rather than incidental occurrence: the organization has determined which points in its architecture carry the responsibility of checking and enforcing rules before data or transactions are allowed to cross a boundary. In practice the phrase appears in control language (e.g., when transferring information between systems representing different security domains with different security policies, information owners/stewards provide guidance at these designated locations between interconnected systems) to convey that enforcement is neither ad hoc nor emergent but is a deliberate architectural commitment. The whole phrase is therefore a compositional description — "designated" is an ordinary adjective modifying the well-defined technical noun phrase "policy enforcement point" — rather than an independentlyControl
designated sourcenounMWEAn endpoint — a network, individual, or device — that has been explicitly authorized and named in an information flow control policy as a permitted origin of information movement within or between systems, distinct from *who* may access the information. Flow control policies operate on the characteristics of the information or the information path, and enforcement is carried out in boundary protection devices such as firewalls, routers, and gateways that apply rule sets or packet- and message-filtering capabilities. In practice, organizations use information flow control policies and enforcement mechanisms to govern the movement of sensitive data (e.g., CUI) between designated sources and destinations, regulating *where* information may travel rather than merely *who* may see it. The expression is strictly paired — a source has meaning only relative to a corresponding destination — and the "designated" qualifier signals that the endpoint has been deliberately enumerated in policy, not simply inferred at runtime.NetworkRegulatedCUI
