MULTI-TIER SECURITY TECHNIQUE FOR DATA LEAKAGE DETECTION AND PREVENTION IN FOG COMPUTING ENVIRONMENT.

In this growing world of technology, Cloud computing is accomplishing stardom because of its usage and storage which is accommodate to users for personal as well as business prospects is rising its requirements. Most of users are devoted cloud computing for its fluidity and ease of access. Cloud computing is a consolidation of service oriented architecture and various computing procedures such as virtualization, fluidity, service-oriented architecture, and assets management. The reinforcement of Cloud computing technology handle various analytical problems such as security, availability, accountability, confidentiality, privacy, data provenance, customization, performance unpredictability, technology bottlenecks, data leakage, data remanence, data inter portability etc., which are addressed in many researches. Very ordinary threat today?s in geographical distributed cloud frame is data leakage. It is examined as the top threats to user data in cloud environment. To conquer this threat a technique is required which can detect the malicious activities. Combination of Fog computing and cloud computing are such a paradigm which helps in monitoring and identifying the unauthorized accesses. As we know that Fog computing is well suited for geographical distributed cloud surroundings to provide better security. So, it is important to provide secured Multi-tier technique for data leakage detection and prevention in fog computing environment. In this paper we are introducing resource and security algorithm along with the architecture. It is hard to trust the third party service provider. This algorithm has two accepts such as providing a secure resource between two cloud servers which are geographically distributed and ensuring the high security in multiple level.
