Vulnerability retrospection of security solutions for software-defined Cyber-Physical System against DDoS and IoT-DDoS attacks

摘要

The wide dispersion of the Internet of Things (IoT), Software-defined Networks and Cloud Computing have given the wings to Cyber-Physical System adoption. The newfangled society relies so much on Cyber-Physical Systems, such as Smart Cities, Smart Agriculture, Medical Cyber System, that a dearth to any of the available services may lead to severe concerns. The IoT devices are unwittingly contributing to the denial of service attacks. Though the neoteric Software-defined Anything (SDx) paradigm has offered effective solution approaches to catastrophic IoT-based DDoS attacks, the novel designed solutions confront various vulnerabilities due to less secure IoT devices, high-volume real-time network traffic generated by the colossal amount of IoT devices, etc.In this paper, we present a comprehensive survey on vulnerability analysis of security solutions for Software-defined Cyber-Physical System. The paper delineates the architectural details of the Software-defined Cyber-Physical System and recommends amalgamation of Fog Computing as one of the architectural layers for overcoming a number of vulnerabilities. As contemporary technologies like IoT, Software-defined Networking and Cloud Computing are the soup ingredients of the Software-defined Cyber-Physical System, each of the individual components has been auscultated individually for security vulnerabilities with a focus on Distributed Denial of Service (DDoS and IoT-based DDoS) attacks. To anticipate the future recasting of the novel paradigm, we discuss the ongoing research and detailed vulnerability analysis with a focus on resiliency, performance, and scalability. Last but not least, we discuss the lessons learned and prospects to conclude.
