WebApr 2, 2024 · An LDoS attack is an intelligent type of DoS attack, which reduces the quality of network service by periodically sending high-speed but short-pulse attack traffic. Because of its concealment and low average rate, the traditional DoS attack detection methods are challenging to be effective. The existing LDoS attack detection methods generally ... WebThe logically centralized controller is always an attractive target for the Distributed Denial of Service (DDoS) attacks. According to various specifications, the low-rate DDoS attack is often not easy to detect against SDN because attackers behave like legitimate traffic. ...

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 ... 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.

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. WebShrew DDoS is also known as ROQ (Reduction of Quality) attack. Because of low flow cyclical attacks, the server is forced to provide low quality services. An attacker needs to send a request to the server at a certain frequency to obtain the execution of the server TCP (Transmission Control Protocol) timer.
