We propose a cloud migration strategy that migrates applications and services running on multiple virtual machines (VMs) from one cloud environment to another. Current migration techniques mostly focus on migrating VMs between physical servers that are placed inside a single cloud. In this work, we consider an automated cloud migration system that enables a cloud migration of multiple VMs between...
In order to defend a cloud computing system from security attackers, an intrusion detection system (IDS) is widely used to inspect suspicious traffic on the network. However, the processing capacity of an IDS is much smaller than the amount of traffic to be inspected in a large-scaled network system. In this paper, we propose a traffic sampling strategy for software-defined networking (SDN) that fully...
We propose a scalable intrusion detection system (IDS) architecture on a software-defined networking (SDN) environment implemented using a virtualization infrastructure called a Kernel-based Virtual Machine (KVM). In this virtual environment, virtual machines running IDSs, the SDN controller, and network attack software are connected with each other through OpenFlow-enabled software switches. This...
