Detection and mitigation of security attacks using real time SDN analytics

Abstract

Software Defined Network (SDN) is a proposal to networking world for global administration and management of network services. It also provides an abstraction of networking elements. Most of the security innovations in SDN are bound to an OpenFlow security framework which creates and implement security policies while detecting malicious traffic, that too in a flexible way. Existing methodologies convert policies into human readable form, which reduces the complexity. The proposed system considers detection and mitigation of attacks in single domain topology. The attacks will be the handled at the processing units and it creates on-demand policies to mitigate the attacks with the aid of real time SDN analytics. Once an attack is detected by the processing unit, mitigation can be performed by the system automatically. The system also considers how the above approach can be used in an inter-domain SDN.
