Professional Security Institute Practice Exam

The correct answer highlights essential phases in developing an effective incident response plan. "Preparation, detection, containment, eradication, recovery, and lessons learned" reflects a comprehensive approach that encompasses the full lifecycle of incident management.

Preparation entails establishing protocols and training personnel so the team is ready when an incident occurs. Detection involves identifying threats and vulnerabilities through monitoring and alerts. Containment focuses on limiting the damage during an incident, while eradication aims to eliminate the underlying threat from the system. Recovery is crucial for restoring systems to normal operation, and the lessons learned phase emphasizes the importance of reviewing incidents to improve future responses and prevent reoccurrences. This structured framework ensures that all critical aspects of incident response are addressed, making it a robust approach to managing security incidents.

The other options do not provide a complete or structured method for responding to incidents, which is why they are inadequate compared to the comprehensive approach offered by the correct answer.
