designated personnel

A 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.
