This paper evaluates a mechanism for applying machine learning (ML) to identify over-constrained IaaS virtual machines (VMs). Herein, over-constrained VMs are defined as those who are not given sufficient system resources to meet their workload specific objective functions. To validate our approach, a variety of workload-specific benchmarks inspired by common Infrastructure-as-a-Service (IaaS) cloud...

Modern virtual machine (VM) management software enables consolidation of VMs for power savings or load-balancing for performance. While existing literature provides various methods for computing a better load-balanced, or consolidated goal state, it fails to adequately suggest the best path from the system’s current state to the desired goal allocation. This paper discusses an approach to efficient...
The ability to accurately determine the geographic location of an arbitrary IP address has potential in many applications. Previous methods based on observing the relationship between network delay and physical distance are inaccurate. Methods based on delay similarity are more accurate, but inefficient because they need information on a large number of landmark nodes near the destination to be collected...
The Blackhole Exploit Kit (BEK) has been called the “Toyota Camry” of exploit kits — cheap, readily available and reliable. According to some estimates, it was used to enable the majority of malware infections in 2012. One major infection vector for BEK is through Twitter. In this paper, we analyze over two months of Twitter data from May through July of 2012 and identify user accounts affected by...
