Network Functions Virtualization (NFV) has provided a new way to design and deploy network security services, but it may fail to build a practically useful ecosystem that seamlessly integrates network security services if there is no standard interface between them. We propose a generic architecture for security management service based on Network Security Functions (NSF) using NFV. The proposed architecture allows users to define their security requirements in a user-friendly manner by providing the users with high-level security interfaces that do not require specific information about network resources and protocols. We design basic components (e.g., Security policy manager, NSF capability manager, Application logic, Policy updater and Event collector) and interfaces for the proposed architecture. We introduce three use cases: (1) blacklists of dangerous domains, (2) time-dependent access control policies and (3) detection of suspicious calls for VoIP-VoLTE services. We also explain how to implement our proposed architecture with an illustrative example. Furthermore, we discuss several technical challenges to deploy the proposed architecture in a real network environment.

As Internet of Things (IoT) devices become more and more prevalent, it is important for research to be done around the security and integrity of them. By doing so, consumers can make well-informed choices about the smart devices that they purchase. This poster presents information about how three different IoT-specific malware variants operate and impact newly connected devices.
