Cloud-based security research testbed: A DDoS use case

In this paper we present a cloud-based research testbed designed to aid network security managers. The testbed enables operators to emulate various network topologies, services, and to analyze attacks threatening these systems. A possibility to test results of network management measures is desired, since testing these measures in a production environment is always not possible. We demonstrate a testbed use case, which aids to scrutinize network behavior under attack. Our use case is based on a large DDoS attack which targeted network infrastructure and web servers in Czech Republic in March, 2013.
