In incident response, which action initiates the process when a suspected breach is detected?

• A. Conduct a periodic security assessment.
• B. Delay notification to avoid panic.
• C. Block all user access immediately.
• D. Activate incident response, contain, assess impact, notify stakeholders, and remediate.

Answer: (D)

When a suspected breach is detected, the immediate action is to activate the incident response plan and start the guided cycle: contain the breach to limit damage, assess the impact to understand scope, notify stakeholders as required, and remediate to restore and improve defenses. This approach provides a coordinated, preplanned response rather than ad hoc moves, ensuring evidence is preserved, communications are proper, and the organization can recover efficiently. Periodic security assessments are ongoing preventive activities, not the triggered response you initiate after a breach is detected. Delaying notification to avoid panic undercuts transparency, may violate legal or regulatory requirements, and hinders timely containment and remediation. Blocking all user access immediately can be disruptive and may be inappropriate without first assessing the breach and implementing targeted containment to preserve operations and evidence. The full incident response activation—contain, assess, notify, and remediate—is the correct, structured way to begin handling a suspected breach.
