Voluntarily sharing information with external stakeholders to achieve broader cybersecurity situational awareness is an activity recommended by the _________ function within the NIST CSF.

Question

BlackTom AI · Accepted Answer

The Respond function within the NIST Cybersecurity Framework covers containment, mitigation, coordination and communications — activities that explicitly include sharing information with external stakeholders to improve situational awareness and enable coordinated response.

1) Relevant knowledge points and concepts
- NIST CSF defines five core functions: Identify, Protect, Detect, Respond, Recover.
- The Respond function’s purpose is to take action regarding a detected cybersecurity event. Key categories under Respond include response planning, communications/coordination, analysis, mitigation, and improvements.
- Communications and coordination under Respond emphasize sharing information internally and externally (e.g., partners, ISACs, law enforcement) to support incident handling and broader awareness.

2) Step‑by‑step reasoning
- The question asks which CSF function recommends voluntarily sharing information with external stakeholders to achieve broader cybersecurity situational awareness.
- Compare each option to the CSF functions:
  - Recover: focuses on restoring capabilities and services after an incident and lessons learned for resilience.
  - Respond: focuses on actions during and immediately after an incident, including coordinated communications and sharing information with external parties.
  - Protect: focuses on safeguards to limit or prevent cybersecurity events (access control, training, maintenance).
  - Detect: focuses on timely discovery of events (monitoring, detection processes).
- The activity described — voluntarily sharing information with external stakeholders to enhance situational awareness — is a communications/coordination activity that is a core part of Respond.

3) Calculations
- Not applicable (no numeric calculations required).

4) Why the correct answer is correct
- Respond explicitly includes the Communications/Coordination category which covers sharing incident information with external stakeholders to enable coordinated response and improve situational awareness. That matches the activity described.

5) Why the other options are incorrect (brief)
- Recover: concerned with restoration and recovery, not primarily proactive external info sharing.
- Protect: about preventive safeguards, not incident coordination with external stakeholders.
- Detect: about identifying events, not the subsequent coordinated information sharing activity.

Conclusion: The correct answer is Respond, which matches the provided answer.
