Filtering of Shrew DDoS Attacks in Frequency Domain
—The shrew Distributed Denial of Service (DDoS) attacks are periodic, bursty, and stealthy in nature. They are also known as Reduction of Quality (RoQ) attacks. Such attacks coul...

Collaborative detection and filtering of shrew DDoS attacks using spectral analysis
This paper presents a new spectral template-matching approach to countering shrew distributed denial-of-service (DDoS) attacks. These attacks are stealthy, periodic, pulsing, and ...

A Novel Embedded Accelerator for Online Detection of Shrew DDoS Attacks
∗ As one type of stealthy and hard-to-detect attack, lowrate TCP-targeted DDoS attack can seriously throttle the throughput of normal TCP flows for a long time without being noti...

Spectral Analysis of TCP Flows for Defense Against Reduction-of-Quality Attacks
Abstract - The RoQ (Reduction-of-Quality) attacks are lowrate DDoS attacks that degrade the QoS to end systems stealthily but not to deny the services completely. These attacks are...
