This paper presents the LogDrive framework for mitigating the following problems of storage forensics in Infrastructure-as-a-Service (IaaS) cloud environments: volatility, increasing volume of forensic data, and anti-forensic attacks that hide traces of incidents in virtual machines. The proposed proactive data collection function of virtual block devices mitigates the problem of volatility within...
Preservation and data collection in cloud environments are difficult because forensic data are volatile and they are scattered in many servers. This paper describes a novel surveillance mechanism for virtual block devices on IaaS cloud environments. We first describe some related work on backup applications, versioning file systems, and virtual machine introspection systems that can be applied to...
Current computer forensics tools have some limitations on anti-forensics attacks, cloud computing, and a large increase in the size of forensics targets. To solve these problems, this paper proposes a system that preserves storage data on virtual machines by acquiring all data sectors with time stamps. The proposed system can restore a previous state of a block device at any date and time that is...
This paper shows the design and implementation of a Role Based Access Control (RBAC) mechanism for securing a hypervisor called BitVisor. BitVisor is a small hypervisor that provides security functions like encryption services for I/O devices in its hypervisor-layer. BitVisor enforces security functions without the help of guest OSs, but it only supports a static configuration file for machine set...
Our proposed simple device authentication framework aims to provide device-oriented authentication and authorization mechanisms for non-PC Internet-ready information appliances. The purpose of the framework is to prevent device spoofing, and to restrict unauthorized access to the device in a future ubiquitous network. We have developed the novel smart card software to achieve peer to peer device-oriented...
In future ubiquitous networks, devices that accept any connections over a network will need to verify the identity of a connecting peer to prevent device spoofing. In this paper, we propose an authentication framework not for human beings, but for devices. The proposed Simple Device Authentication Framework has the advantages of realizing both production-level identity using serial numbers initialized...
