Cloud computing is a long-established technique which deals with storage and processing of information. In cloud computing, any user is liable to pay and demand according to its particular needs. Due to various limitations of cloud computing like higher latency and more bandwidth consumptions for transmitted information, the origination of Fog computing was essential. Fog computing inherits all the advantages of cloud computing, and also brings computing at the network's edge. In addition, security is a very serious concern for cloud computing. In this paper, fog computing is used as a defensive approach from the day-to-day increasing security threats particularly DDoS attacks in cloud computing. Here an architecture has been proposed to obstruct the malicious traffic generated by the DDoS attack from user to the cloud by utilizing the benefits of fog computing. Fog functions as a filtering layer for the traffic generated and is placed between user and cloud. This paper primarily works to improve the overall performance of the network and enhances reduction in the traffic forwarded to the cloud.
