With the rise of data exchange over the Internet, information-centric networks have become a popular research topic in computing. One major research topic on Information Centric Networks (ICN) is the use of data caching to increase network performance. However, research in the security concerns of data caching networks is lacking. One example of a data caching network can be seen using a Mobile Ad Hoc Network (MANET).
Recently, a study has shown that it is possible to infer military activity through cache behavior which is used as a basis for a formulated denial of service attack (DoS) that can be used to attack networks using data caching. Current security issues with data caching networks are discussed, including possible prevention techniques and methods. A targeted data cache DoS attack is developed and tested using an ICN as a simulator. The goal of the attacker would be to fill node caches with unpopular content, thus making the cache useless. The attack would consist of a malicious node that requests unpopular content in intervals of time where the content would have been just purged from the existing cache. The goal of the attack would be to corrupt as many nodes as possible without increasing the chance of detection. The decreased network throughput and increased delay would also lead to higher power consumption on the mobile nodes, thus increasing the effects of the DoS attack.
Various caching polices are evaluated in an ICN simulator program designed to show network performance using three common caching policies and various cache sizes. The ICN simulator is developed using Java and tested on a simulated network. Baseline data are collected and then compared to data collected after the attack. Other possible security concerns with data caching networks are also discussed, including possible smarter attack techniques and methods.
