Computer Hacking Forensic Investigator (CHFI v10) — Question 524

Bob works as information security analyst for a big finance company. One day, the anomaly-based intrusion detection system alerted that a volumetric DDOS targeting the main IP of the main web server was occurring. What kind of attack is it?

Answer options

• A. IDS attack
• B. APT
• C. Web application attack
• D. Network attack

Correct answer: D

Explanation

The correct answer is D, Network attack, as a volumetric DDoS attack overwhelms the network's bandwidth, impacting the availability of the targeted server. Options A and B are incorrect because IDS and APT refer to different concepts that do not specifically describe the nature of a DDoS attack. Option C is also incorrect since a web application attack targets application-level vulnerabilities rather than overwhelming network resources.
