Q83
Single choice
A telecommunications provider in Toronto operates a monitoring platform that analyzes inbound traffic streams during suspected denial-of-service conditions. The system converts traffic measurements into signal components and evaluates their energy across multiple frequency ranges to distinguish abnormal traffic bursts from background network noise.
Rather than focusing on traffic baselines or identifying the exact statistical breakpoint where behavior changes, the platform identifies anomalies by decomposing traffic signals into spectral components for analysis.
Which DDoS detection technique is being used in this scenario?
