Certified Incident Handler (CIH) Practice Ecam

What kind of analysis helps in identifying the cause of DDoS incidents?

1. User behavior analysis

2. Post-attack forensic data analysis

3. Routine system updates

4. Employee training sessions

The correct answer is: Post-attack forensic data analysis

Post-attack forensic data analysis is crucial in identifying the causes of Distributed Denial of Service (DDoS) incidents. This type of analysis involves examining the logs, traffic patterns, and any anomalies that occurred during a DDoS attack to determine how the attack was executed, its origin, and the vulnerabilities that were exploited. By performing a thorough forensic analysis, incident handlers can piece together the attack's timeline, identify the tactics and techniques used by attackers, and enhance their understanding of the attack vectors. This knowledge is not only invaluable for preventing future incidents but also for improving response strategies and bolstering the overall security posture. In contrast, user behavior analysis typically focuses on examining how users interact with systems to identify abnormalities or potential insider threats rather than addressing external attacks like DDoS. Routine system updates are essential for security hygiene and can help reduce vulnerabilities but do not provide insights into specific incidents once they have occurred. Lastly, employee training sessions are significant for general security awareness and best practices, but they do not directly contribute to analyzing the specifics of a DDoS incident.
