A Novel Technique for Detecting DDoS Attacks at Its Early Stage
نویسندگان
چکیده
Spoofing source IP addresses is always utilized to perform Distributed Denial-of-Service (DDoS) attacks. Most of current detection and prevention methods against DDoS ignore the innocent side, whose IP is utilized as the spoofed IP by the attacker. In this paper, a novel method has been proposed to against the direct DDoS attacks, which consists of two components: the client detector and the server detector. The cooperation of those two components and their interactive behavior lead to an early stage detection of a DDoS attack. From the result of experiments, the approach presented in this paper yields accurate DDoS alarms at early stage. Furthermore, such approach is insensitive to the false suspect alarms with adopted evaluation functions.

Distributed Denial of Service (DDoS) is a common attack in recent years that can deplete the bandwidth of victim nodes by flooding packets. Based on the type and quantity of traffic used for the attack and the exploited vulnerability of the target, DDoS attacks are grouped into three categories as Volumetric attacks, Protocol attacks and Application attacks. The volumetric attack, which the pro...

It is a pressing task to fight off DDoS (Distributed Denial-of-Service) attacks effectively on the Internet. However, despite that there has been a plethora of efforts suggested in the literature to combat DDoS attacks, we are yet to see a really practicable efficient solution. First of all, such a solution has to be scalable because we need to inspect and process a gigantic amount of traffic f...

When service system is under DDoS attacks, it is important to detect anomaly signature at starting time of attack for timely applying prevention solutions. However, early DDoS detection is difficult task because the velocity of DDoS attacks is very high. This paper proposes a DDoS attack detection method by modeling service system as M/G/R PS queue and calculating monitoring parameters based on...
