Contrast operating system installed on traditional PC, operating system installed to mobile IP host is a status not to be established a definite monopoly system. Accordingly, for the time being, it is expected that operating system operated in mobile IP host will be used various operating systems. Regardless of operating system, this condition is a very vulnerable to modified virus. Because operating system used in an individual host is very diverse, It makes technical development to cure complicated in detection efficiently these virus. In this thesis, By using VMware under the various operating system, I designed and implemented system which is able to test a modified virus. Also I implemented prototype system to operate under the real mobile condition.

In this paper, we proposed new virtualization technology that is more convenient and stable in local computing environment, then found technique elements need to desktop virtualization which is based on clients in various virtualization technologies. After running excution of process explorer utility in user level virtualization and VMWare, we found memory capacity that is used 30.1MB in VMWare and 16.6MB in user level virtualization respectively to compare private bytes each of process. We found no significant difference of CPU utilization which is executed application program in local computing environment and user domain with user level virtualization. In this result, proposed virtualization technology is able to minimize performance degradation of local computing environment.

Virtualization is a technology that uses a logical environment to overcome physical limitations in hardware. As a part of cost savings and green IT policies, there is a tendency in which recent businesses increase the adoption of such virtualization. In particular, regarding the virtualization in desktop, it is one of the most widely used technology at the present time. Because it is able to efficiently use various types of operating systems in a physical computer. A virtual machine image that is a key component of virtualization is difficult to investigate. because the structure of virtual machine image is different from hard disk image. Therefore, we need researches about appropriate investigation procedure and method based on technical understanding of a virtual machine. In this research, we suggest a procedure of investigation on a virtual machine image and a method for a corrupted image of the VMware Workstation that has the largest number of users.

Comes in into recent times and there is on with a level where the attack against the computer virus and the hacking which stand is serious. The recently computer virus specific event knows is the substantial damage it will be able to occur from our life inside is a possibility of feeling. The virus which appears specially in 1999 year after seemed the change which is various, also the virus of the form which progresses appeared plentifully The part virus does it uses the password anger technique which relocates the cord of the oneself. Hereupon consequently the vaccine programs in older decode anger to do the password anger of the virus again are using emulation engine. The password anger technique which the like this virus is complicated and decode anger technique follow in type of O.S. and the type is various. It uses a multi emulation engine branch operation setup consequently from one system and to respect it will be able to use a multiple operation setup together it will use the VMware which is an application software which it does as a favor there is a possibility where it will plan 'Virus Test Simulation' and it will embody.

Recently, cloud computing is one of the parts showing the biggest growth in the IT market and is expected to continue to grow into. Especially, many companies are adopting virtual desktop infrastructure as private cloud computing to achieve in saving the cost and enhancing the efficiency of the servers. However, current digital forensic investigation methodology of cloud computing is not systematized scientifically and technically. To do this, depending on the type of each cloud computing services, digital evidence collection system for the legal enforcement should be established. In this paper, we focus on virtual desktop infrastructure as private cloud computing and introduce the most widely used around the world desktop virtualization solutions of VMware, Citrix, and Microsoft. And We propose digital forensic investigation methodology for private cloud computing that is constructed by these solutions.

The personal workspace consists of user- specified computing environment such as user profile, applications and their configurations, and user data. Mobile computing devices (i.e., cellular phones, PDAs, laptop computers, and Ultra Mobile PC) are getting smaller and lighter to provide personal work-space ubiquitously. However, various personal work-space mobility solutions (c.f. VMWare Pocket ACE[1], Mojopac[2], u-PC[3], etc.) are appeared with the advance of virtualization technology and portable storage technology. The personal workspace can be loaded at public PC using above solutions. Especially, we proposed a framework called ubiquitous personal computing environment (u-PC) that supports mobility of personal workspace based on wireless iSCSI network storage in our previous work. However, previous u-PC could support limited applications, because it uses IRP (I/O Request Packet) forwarding technique at filter driver level on Windows operating system. In this paper, we implement OS-level virtualization technology using system call hooking on Windows operating system. It supports personal workspace mobility and covers previous u-PC limitation. Also, it overcomes personal workspace loading overhead that is limitation of other solutions (i.e., VMWare Pocket ACE, Mojopac, etc). We implement a prototype consisting of Windows XP-based host PC and Linux-based mobile device connected via WiNET protocol of UWB. We leverage several use~case models of our framework for proving its usability.
