How should an organization ensure the incident response plan remains current with industry developments?

• A. Keep the plan unchanged
• B. Rely on external advisories only
• C. Develop a process to modify and evolve the plan based on lessons learned and industry developments
• D. Implement changes only after a major breach

Answer: (C)

Keeping an incident response plan up to date means treating it as a living document that changes with new threats, lessons learned from drills and incidents, and evolving industry guidance. The best approach is to establish a formal process to review and update the plan regularly, incorporating after-action findings, tabletop exercise results, and relevant industry developments such as threat intelligence and regulatory updates. This keeps roles, contacts, and procedures current and ensures containment and communication steps reflect the organization’s actual capabilities.

Relying solely on external advisories misses internal context and the specific risks an organization faces, and leaving the plan unchanged or waiting for a major breach is risky. A proactive, structured process that evolves the plan based on lessons learned and industry developments provides timely improvements and strengthens readiness across the organization.
