What are the common challenges associated with securing software-defined networks (SDNs)? In the paper: Schonberg et al. (2010): How to secure software-defined networks (SDNet): Three challenges. Using SDNs identified by the GPRS search tool, Schonberg et al. addressed all the potential challenges related with the secure and decentralized use of SDNs in their work and showed the potential benefits that they could offer. They were also able to estimate the benefit and pay-off for the SDNs by using new and existing sensors. For future studies we are to examine their utilization on the SDNet and apply our results to future work at their network-centric centers. Ranard Düben was supported by the European Research Council.
