I am a PhD candidate and member of the Network Architecture Lab at EPFL advised by Prof. Katerina Argyraki.
Before joining EPFL, I earned my MS(2010) and BS(2007) at University of Ioannina, where I was a member of the Systems Research Group lead by Prof. Stergios Anastasiadis.
My research focusses on mitigating bandwidth-flooding attacks (a type of Denial of Service attacks which causes links to saturate and drop legitimate traffic). A common theme which is prevalent among many existing mitigation techniques is that each of them is susceptible to one of the following: the solution can either be evaded by a clever adversary, the solution requires too much network-state (i.e., it requires the network core to memorize more rules than routers can handle), or the solution requires a high degree of collaboration among ISPs (i.e., to a degree that is not afforded by ISP policies).
As such, my goal is two-fold and hinges on the following questions:
- "How much network state does the network really have to keep track of in order to counter bandwidth-flooding attacks?"
- "Can we leverage existing technology to make the Internet that we have more resistant to bandwidth-flooding attacks?"
