Securing Internet of Things is a challenge because of its multiple points of vulnerability. In particular, Distributed Denial of Service (DDoS) attacks on IoT devices pose a major security challenge to be addressed. In this paper, we propose a DNS query-based DDoS attack mitigation system using Software-Defined Networking (SDN) to block the network traffic for DDoS attacks. With some features provided...
Securing Internet of Things (IoT) systems is a challenge because of its multiple points of vulnerability. A spate of recent hacks and security breaches has unveiled glaring vulnerabilities in the IoT. Due to the computational and memory requirement constraints associated with anomaly detection algorithms in core networks, commercial in-line (part of the direct line of communication) Anomaly Detection...
This paper proposes a framework for security services using Software-Defined Networking (SDN) and Interface to Network Security Functions (I2NSF). It specifies requirements for such a framework for security services based on network virtualization. It describes two representative security systems, such as (i) centralized firewall system and (ii) DDoS-attack mitigation system. For each service, this...
This paper proposes a framework for security services using Software-Defined Networking (SDN) and specifies requirements for such a framework. It describes two representative security services, such as (i) centralized firewall system and (ii) centralized DDoS-attack mitigation system. For each service, this paper discusses the limitations of legacy systems and presents a possible SDN-based system...
