Vulnerability Detection of Android System in Fuzzing Cloud

The rapid growth of Android system has encountered enormous security challenges. The vulnerabilities caused by the limited security models, coarse permission system and code flaws lead to private information leakage, deny of service, potential costs, etc. To detect these vulnerabilities, some analysis and security testing methods have been presented. However, most of these methods focus on certain aspects, for example, applications, permission, or capability leakage. In this paper, we propose a new detection paradigm named Fuzzing Cloud to detect vulnerabilities in Android system. Firstly, the architecture of fuzzing cloud is introduced, and the fuzzing nodes are investigated. Then, each layer of the Android system is decomposed into separated modules, and the fuzzing test cases are created with the endless capacity of processing power and storage in fuzzing cloud. Finally, the prototype of fuzzing cloud has been implemented, and some separated modules have been tested. The experiment results show that some vulnerabilities can be detected by the fuzzing cloud. It is also believed that after small extension, fuzzing cloud can detect vulnerabilities in other systems.
