Control statement

Incorporate security and privacy roles and responsibilities into organizational position descriptions.

Official NIST discussion

Discussion

Specification of security and privacy roles in individual organizational position descriptions facilitates clarity in understanding the security or privacy responsibilities associated with the roles and the role-based security and privacy training requirements for the roles.

Original Bare Metal Cyber perspective

From control text to operational evidence

Use Position Descriptions as a testable risk decision. Translate the official statement into accountable people, repeatable processes, configured technology, and evidence that demonstrates the outcome over time. In this family, pay particular attention to personnel risk, screening, agreements, transfer, termination, and access consequences.

Implementation workflow

  • Define the control boundary, responsible owner, inherited portions, and systems or processes in scope.
  • Resolve each organization-defined parameter before declaring the control implemented.
  • Document how the implementation satisfies every clause of the official control statement.
  • Collect evidence as a normal byproduct of operation rather than only before an assessment.
  • Review exceptions, changes, and monitoring results on a risk-based cadence.

Evidence examples

  • screening and suitability records
  • access agreements
  • transfer and termination checklists
  • role change and offboarding evidence

Common failure patterns

  • access persists after transfer or separation
  • contractor lifecycle handled outside normal controls
  • sensitive-role screening not risk based
  • termination actions cannot be shown to occur promptly

Questions practitioners should ask

  • What risk decision is this control intended to support in this system?
  • Which parts are implemented locally, inherited, shared, or not applicable—and what evidence supports that decision?
  • Do the documented narrative, deployed configuration, operating process, and collected evidence agree?
  • What event or threshold requires the implementation to be reviewed or changed?
