Which detection technique is described as identifying changes in the statistical properties of traffic over time (change-point detection)?

• A. Sequential Change-Point Detection
• B. HOIC
• C. LOIC
• D. AnDOSid

Answer: (A)

This question is about detecting shifts in traffic behavior as data arrives. The idea is to monitor statistics like the average rate, variance, or the overall distribution of traffic over time and spot when they change abruptly. Sequential change-point detection is specifically designed for this: it analyzes traffic in real time and raises an alert when the current statistics deviate from the established baseline, indicating a new regime or anomaly. In a network context, you might watch packets per second or connection attempts, and a sudden jump in the mean or variance signals a change point. The other options describe tools used to generate traffic for denial-of-service testing, not methods to observe and identify changes in traffic patterns, so they don’t fit as detection techniques.
