Which action aligns with best practice for security follow-up after an incident?

• A. Document follow-up assignments, lessons learned, and planned improvements in a debrief.
• B. Close the incident without documenting follow-up.
• C. Wait for weeks before following up.
• D. Blame colleagues publicly.

Answer: (A)

Documenting follow-up actions, lessons learned, and planned improvements in a formal debrief is essential after an incident. This approach creates a clear, actionable record of what happened, who is responsible for each corrective step, and when those steps should be completed. It ensures accountability, closes security gaps, and provides a basis for updating procedures and training to reduce the chance of a recurrence. Elements to include typically are assigned owners, due dates, prioritized actions, changes to procedures or equipment, and any follow-up communications to stakeholders.

Closing without documenting follow-up misses the opportunity to learn and improve. Waiting weeks to act allows risks to persist and gaps to widen. Publicly blaming colleagues damages trust and teamwork and is counterproductive to better security outcomes.

So, the best practice is to conduct a thorough debrief that records follow-up assignments, lessons learned, and planned improvements.
