K.A. Sadiq, A.F. Thompson, O.A. Ayeni . Mitigating DDoS Attacks in Cloud Network using Fog and SDN: A Conceptual Security Framework. International Journal of Applied Information Systems. 12, 32 ( August 2020), 11-16. DOI=10.5120/ijais2020451877
In recent years, Cloud computing has changed the entire Information Technology (IT) domain due to bi-overlay focus points as against the traditional computer networks, i.e., capital expenditure (CapEx) and operational (OpEx) reduction. Both Cloud users’(CS) data and business reasons are stored in remote data centers and accessed through the network, typically the internet. The geographic distribution of Cloud data centers poses a risk to Cloud security. Consequently, a Distributed Denial of Service (DDoS) attacks remains the most prominent threats to Cloud data availability, confidentiality, and integrity. This paper explores Fog computing and Software-defined Networking (SDN) to mitigate Cloud networks against DDoS attacks. Fog computing center intermediate node between the CS and the data center, ”Fog computing is proposed as an additional firewall to complement the security of the Cloud networks due to its closeness to the ground, and internet of things IoT devices and also ensures better security, Quality of Service (QoS), low latency, real-time data process, location awareness, and mobility support.” Additionally, SDN that decouples the data plan (hardware) from the control plan (software) is employed to provide a global view of the Cloud network, and better management of the entire security architecture. The research presents DDoS security challenges and conceptual description of mitigating it with Fog computing and SDN.
