SDNForensics: A Comprehensive Forensics Framework for Software Defined Network
Shuhui Zhang, Xiang-xu MENG, Lianhai Wang · 2017
Software-defined networking (SDN) is an emerging network architecture, which decouples the control and data planes of a network.Owing to its openness and standardization, SDN enables researchers to design and implement new innovative network functions and protocols in a much simpler and flexible way.However, the dynamism of programmable networks also brings potential new security challenges relating to various attacks such as scanning, spoofing attacks and denial-of-service attacks.We survey existing research efforts relating to both security challenges and promising solutions for SDN security problems.To the best of our knowledge, there are no published papers on SDN forensics.Before describing our forensics framework, the design goals and technical requirements of SDN forensics are discussed.Then SDNForensics, a comprehensive forensics framework, is proposed for the collection and analysis of digital evidence, built on SDN infrastructure.
