Interest Flooding Attack

An Interest Flooding Attack (IFA) is a denial-of-service attack in an Information-centric network (or Content-Centric Networking (CCN) or Named Data Networking (NDN)). An attacker requests existing or non-existing content in order to overload the distribution infrastructure.[1] This can be implemented by sending Interest packets, which are not resolved at all or not resolved fast enough and thus lead to malicious CPU or memory consumption.

This attack is an open problem in ICN, although some countermeasures exist.[2]
