A survey of effects and detection of attacks with preventive measures to reduce DoS attacks on SDN

Abstract

Abstract: The emergence of cloud services has challenged the advent of a digital automated society where almost everything is connected and accessible from everywhere. The traditional networks are complicated and very hard to maintain as the control plane and the data plane are put together. The SDN (Software Defined Networks) is an evolving technology that commits to transform this by separating the network’s control logic from the underlying routers and switches, making the entire network centralized and creates the talent to program the network. SDN market is expanding continuously at a rapid pace. There is a demand for SDN from various evolving industries such as health care, military, manufacturing, retail and custom goods and telecommunications among many others. The separation of control plane and data plane brings new security challenges like the DoS attacks specific to OpenFlow SDN networks. The major threat faced by these services is security management. As there are numerous non-recognizable attacks against the cloud environment faced by cloud users, special attention is required for SDN control plane security. DoS attacks are considered a major threat to network, overloading the controller resulting in critical degradation of the overall network performance. This paper is focused on DoS attacks associated with SDN and proposes to work with Moving target defence (MTD) algorithm for security applications.
