Detection of Innovative Low-rate Denial of Service Attacks Against Critical Infrastructures

In the cyber security field, Denial of Service (DoS) attacks are executed to exhaust the resources of the victim, by compromising availability of the targeted system, thus affecting reliability for its intended users. Last-generation threats make use of low bandwidth to target network services. In virtue of this, they are more difficult to counter, and efficient detection is still an open issue in the research field. This chapter focuses on the analysis of the functioning of low-rate DoS attacks targeting network services, with emphasis on web protocols.
