PL-6 — Security-related Activity Planning

From control text to operational evidence

Use Security-related Activity Planning 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 security and privacy planning, architecture, rules of behavior, and lifecycle alignment.

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

• system security and privacy plans
• architecture and data-flow diagrams
• rules-of-behavior acknowledgments
• plan review and approval records

Common failure patterns

• plans copied from templates without system specificity
• diagrams that do not match deployed services
• inherited controls claimed without provider evidence
• plans updated only before assessment

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?
