The Internet of Things is visualized as a fundamental networking model that bridges the gap between the cyber and real-world entity. Uniting the real-world object with virtualization technology is opening further opportunities for innovation in nearly every individual’s life. Moreover, the usage of smart heterogeneous multimedia devices is growing extensively. These multimedia devices that communicate among each other through the Internet form a unique paradigm called the Internet of Multimedia Things (IoMT). As the volume of the collected data in multimedia application increases, the security, reliability of communications, and overall quality of service need to be maintained. Primarily, distributed denial of service attacks unveil the pervasiveness of vulnerabilities in IoMT systems. However, the Software Defined Network (SDN) is a new network architecture that has the central visibility of the entire network, which helps to detect any attack effectively. In this regard, the combination of SDN and IoMT, termed SD-IoMT , has the immense ability to improve the network management and security capabilities of the IoT system. This article proposes an SDN-assisted two-phase detection framework, namely SD-IoMT-Protector, in which the first phase utilizes the entropy technique as the detection metric to verify and alert about the malicious traffic. The second phase has trained with an optimized machine learning technique for classifying different attacks. The outcomes of the experimental results signify the usefulness and effectiveness of the proposed framework for addressing distributed denial of service issues of the SD-IoMT system.

面向多媒体物联网的 SDN 辅助 DDoS 防御框架

物联网被可视化为一种基本的网络模型,它弥合了网络和现实世界实体之间的差距。将现实世界的对象与虚拟化技术相结合,为几乎每个人的生活中的创新开辟了更多机会。此外,智能异构多媒体设备的使用正在广泛增长。这些通过 Internet 相互通信的多媒体设备形成了一种独特的范式,称为多媒体物联网(物联网)。随着多媒体应用中收集的数据量的增加,需要保持通信的安全性、可靠性和整体服务质量。首先,分布式拒绝服务攻击揭示了 IoMT 系统中普遍存在的漏洞。然而,软件定义网络(SDN)是一种新的网络架构,具有整个网络的中心可见性,有助于有效地检测任何攻击。在这方面,SDN和IoMT的结合,称为SD-物联网,具有提升物联网系统网络管理和安全能力的巨大能力。本文提出了一种SDN辅助的两阶段检测框架,即SD-IoMT-Protector,其中第一阶段利用熵技术作为检测指标来验证和警告恶意流量。第二阶段使用优化的机器学习技术进行训练,以对不同的攻击进行分类。实验结果表明所提出的框架对于解决 SD-IoMT 系统的分布式拒绝服务问题的有用性和有效性。
