Shrew ddos
Web(DDoS) attacks [9], [13] are categorized as a new type of hard-to-detect, stealthy attack. This kind of attack can throttle the throughput of TCP flows to as low as 10% of its normal bandwidth usage, and may last for a long time before victims realize its existence. They are also referred as shrew attacks [13], or pulsing attacks [14] in ... WebNov 17, 2005 · Filtering of shrew DDoS attacks in frequency domain Abstract: 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.

WebLow-rate DDoS has a relatively low data rate to elude being detected. The behavior of low-rate DDoS attack likes a shrew can defeat an elephant. Hence, low-rate DDoS attack is called Shrew in early. Because the waveform of low-rate DDoS attack is a series square pulses, someone call low-rate DDoS attack as Pulse DoS (PDoS) attack. Shrew attack [ 18] is one of the most popular types of LR-DDoS attacks which utilizes the vulnerability of TCP’s RTO mechanism. The attacker continuously sends a low volume of attack packets to make TCP timeout for the legitimate flows. The square-wave model for the shrew attack is shown in Fig. 1 which … See more The proposed shrew attack model in SDN-C environment is shown in Fig. 2. The shrew attack is launched by compromising several machines in the network. The machines are compromised by injecting malicious code, … See more The assumptions that have been made in the proposed security model are as follows. 1. 1. The routers are well controlled, and a unique static ID is assigned to each … See more The IP traceback algorithm determines the location of the router which is nearest to the attacker. In the proposed approach, the detection method … See more The proposed approach utilizes entropy variations of source IP addresses and IP packet-sizes for the attack detection. In information theory, entropy measures the uncertainty or … See more
WebSep 1, 2006 · This paper presents a new spectral template-matching approach to countering shrew distributed denial-of-service (DDoS) attacks. These attacks are stealthy, periodic, … WebThe shrew attacks could be even more detrimental to network resources than the flooding type of DDoS attacks. Shrew attacks appear periodically in low volume, thereby damaging the victim servers for a long time without being detected. This in turn leads to denying new visitors to the victim servers (which are mostly e-commerce sites).

Our defense method calls for collaborative detection and filtering (CDF) of shrew DDoS attacks. We detect shrew attack flows hidden in legitimate TCP/UDP streams by spectral analysis against pre-stored template of average attack spectral characteristics.
