How often must the incident response plan be tested?

• A. Monthly
• B. Annually
• C. Every two years
• D. Only after a breach

Answer: (B)

Regular testing of the incident response plan keeps the team ready to detect, respond to, and recover from security incidents. PCI DSS requires this plan to be tested at least annually, and also after significant changes to the plan or to the environment. This frequency ensures the procedures stay effective as systems, personnel, and processes evolve, and it helps validate that roles, escalation paths, communication, containment, and recovery steps actually work in practice. Tests can range from tabletop exercises to simulated breaches or full drills, giving a realistic check without disrupting operations. Waiting for a breach is risky, and testing too frequently (like monthly) isn’t required by the standard and can be unnecessarily burdensome.
