Virtual Network Security: An Important Step towards the Future Internet?

28 February 2013






Network virtualization is the technique that allows the creation of multiple instances of virtual networks over a single physical substrate. This technique has attracted the interest from the academic community, in particular due to its applicability in creating favorable conditions for the evaluation of new architectures for the Future Internet. There is also noticeable interest from major companies within the segment of computer networks, which are starting to manufacture devices supporting virtualization, as well as offering virtual network provisioning services. However, the shared use of routing devices and communication channels brings a series of security related concerns. It is necessary to provide protection to virtual network infrastructures in order to enable their use in real environments and on a large scale. In this talk, I will present a brief review of the state-of-the-art concerning virtual network security. In addition, I will comment the research work that we are doing at INF/UFRGS in the area.
