A Cache Based DoS Attack on Real Information Centric Networking System

Network security is an ongoing major problem in today\u27s Internet world. Even though there have been simulation studies related to denial of service and cache attacks, studies of attacks on real networks are still lacking in the research. In this work, the effects of cache attacks in real information-centric networking systems were investigated. Cache attacks were implemented in real networks with different cache sizes and with Least Recently Used, random and First In First Out algorithms to fill the caches in each node. The attacker hits the cache with unpopular content, making the user request that the results be fetched from web servers. The cache hit, time taken to get the result and number of hops to serve the request were calculated with real network traffic. The results of the implementation are provided with the consideration of different topologies and are compared with existing simulation results
