چکیده (انگلیسی):

Many organizations and service providers have started shifting
from traditional server-cluster infrastructure to cloud-based infrastructure.
The threat of Distributed Denial of Service (DDoS) attack continues to
wreak havoc in these cloud infrastructures. In addition to DDoS attacks, a
new form of attack known as Economic Denial of Sustainability (EDoS)
attack has emerged in recent years. EDoS which is unique to cloud
infrastructure may not be easily detected as with DDoS. Although EDoS
attack is small at the moment, it is expected to grow in the near future in
tandem with the growth in cloud usage. As EDoS has a major impact
economically, it can considered to be more serious than DDoS and many
defence and mitigation mechanisms have been proposed to combat these
attacks. This paper introduces EDoS and how it differs from DDoS. The
existing mitigation techniques are described and the drawbacks of these
techniques are explained.
