A survey of denial-of-service and distributed denial of service attacks and defenses in cloud computing
Cloud Computing is a computingmodel that allows ubiquitous, convenient and on-demand
access to a shared pool of highly configurable resources (e.g., networks, servers, storage, applications
and services). Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) attacks are serious
threats to the Cloud services’ availability due to numerous new vulnerabilities introduced by the
nature of the Cloud, such as multi-tenancy and resource sharing. In this paper, new types of DoS and
DDoS attacks in Cloud Computing are explored, especially the XML-DoS and HTTP-DoS attacks,
and some possible detection and mitigation techniques are examined. This survey also provides
an overview of the existing defense solutions and investigates the experiments and metrics that are
usually designed and used to evaluate their performance, which is helpful for the future research in
the domain
Intelligent Management and Efficient Operation of Big Data
This chapter details how Big Data can be used and implemented in networking
and computing infrastructures. Specifically, it addresses three main aspects:
the timely extraction of relevant knowledge from heterogeneous, and very often
unstructured large data sources, the enhancement on the performance of
processing and networking (cloud) infrastructures that are the most important
foundational pillars of Big Data applications or services, and novel ways to
efficiently manage network infrastructures with high-level composed policies
for supporting the transmission of large amounts of data with distinct
requisites (video vs. non-video). A case study involving an intelligent
management solution to route data traffic with diverse requirements in a wide
area Internet Exchange Point is presented, discussed in the context of Big
Data, and evaluated.Comment: In book Handbook of Research on Trends and Future Directions in Big
