Distributed Denial of Service (DDoS) attack has been bringing serious security concerns on banks, finance incorporation, public institutions, and data centers. Also, the emerging wave of Internet of Things (IoT) raises new concerns on the smart devices. Software Defined Networking (SDN) and Network Functions Virtualization (NFV) have provided a new paradigm for network security. In this paper, we...
This paper proposes an enhanced Interface to Network Security Functions (I2NSF) framework. To improve the whole packet throughput and manage resource of Network Security Functions (NSFs), the enhanced I2NSF framework monitors NSFs and distributes incoming packets to NSFs efficiently. Even if the legacy framework that provides security services using Software-Defined Networking (SDN) and Network Functions...
This paper proposes a framework for security services for Voice over IP (VoIP) and Voice over LTE (VoLTE) in commercial networks using Software-Defined Networking (SDN) and Network Functions Virtualization (NFV). The VoIP/VoLTE services are exposed to several security threats such as Denial-of-Service (DoS) attack, network sniffing, unauthorized services access, and VoIP spam. The conventional security...
