Among the future Internet proposals, the Information-Centric Networking (ICN) research paradigm aims to redesign the Internet's core protocols focusing on contents rather than on hosts. Among the ICN architectures, the Named-Data Networking (NDN) forwards and records users' content requests by their names in routers along the path from one consumer to 1-or-many content sources. The Pending Interest Table (PIT) is the NDN's router component which temporarily records forwarded requests. On one hand, the state in the PIT enables properties like requests aggregation, multicast responses delivery and native hop-by-hop control flow. On the other hand, the PIT stateful forwarding behavior can be easily abused by malicious users to mount disruptive distributed denial of service attacks (DDoS), named Interest Flooding Attacks (IFAs). In IFAs, loosely coordinated botnets flood the network with a large amount of hard-to-satisfy requests with the aim to overload both the network infrastructure and the content producers. In this talk I will summarize the state of the art on the design of countermeasures against the IFA, an NDN-specific security threat to which I devoted much of my PhD research. First, I will introduce existing defense mechanisms and main flaws in the mainstream approach to the defense against this attack. Secondly, I will present some other techniques I propose to counteract certain IFAs, whose design has not been completed yet. Finally, I will share a few more research directions that can be pursued to design more robust forwarding planes for a certain class of ICNs.
