A collaborative approach for a source based detection of botclouds

Since the last years, cloud computing is playing an important role in providing high quality of IT services. However, beyond a legitimate usage, the numerous advantages it presents are now exploited by attackers, and botnets supporting DDoS attacks are among the greatest beneficiaries of this malicious use. In this paper, we present an original approach that enables a collaborative egress detection of DDoS attacks leveraged by a botcloud. We provide an early evaluation of our approach using simulations that rely on real workload traces, showing our detection system effectiveness and low overhead, as well as its support for incremental deployment in real cloud infrastructures.
