Identifikasi Bukti Forensik Jaringan Virtual Router Menggunakan Metode NIST

The evolution information technology has led to the growth of virtualization technology. Router OS is the operating system of the Mikrotik Router, which supports virtualization. Router Os virtualization technique which is easy to run is a metarouter. Metarouter provides benefits such as, building virtual servers, virtual machines, network topology and savings cost. As an object of research, Metarouter introduces challenges to digital forensic investigations, both practitioners and academics. Investigators need to use methodology and tools in order to prove the perpetrators of crimes. This study uses the Windump forensic tool as a means of recording network traffic activity. Network Miner and Wireshark as an analytical tool for identifying digital evidence. The use of the National Institute of Standard and Technology (NIST) method which collection, examination, analysis and reporting, can be repeated and maintained with the same data. Based on experiments with virtual router network traffic testing, the system built has succeeded in obtaining digital evidence, either by direct or indirectly. The system scenario that has been planned succeeded recording 220494 packages, but by the Windump, it is automatically divided into 9 (nine) parts of the package which are Buktidigital0 to Buktidigital8. The inspection stage produces evidence that has been verified by Wireshark and Network Miner. The analysis stage proves that there were attacks carried out by addresses 192.168.10.10 and 192.168.234.10. Based on the results of forensic testing, the use of the NIST method on a forensic system that has been built with a virtual router object can be used by investigators to identify evidence of cyber-attacks.

Efficient operating system level virtualization techniques for cloud resources

Cloud computing is an advancing technology which provides the servcies of Infrastructure, Platform and Software. Virtualization and Computer utility are the keys of Cloud computing. The numbers of cloud users are increasing day by day. So it is the need of the hour to make resources available on demand to satisfy user requirements. The technique in which resources namely storage, processing power, memory and network or I/O are abstracted is known as Virtualization. For executing the operating systems various virtualization techniques are available. They are: Full System Virtualization and Para Virtualization. In Full Virtualization, the whole architecture of hardware is duplicated virtually. No modifications are required in Guest OS as the OS deals with the VM hypervisor directly. In Para Virtualization, modifications of OS is required to run in parallel with other OS. For the Guest OS to access the hardware, the host OS must provide a Virtual Machine Interface. OS virtualization has many advantages such as migrating applications transparently, consolidation of server, online maintenance of OS and providing security. This paper briefs both the virtualization techniques and discusses the issues in OS level virtualization.

Towards database virtualization for database as a service

Advances in operating system and storage-level virtualization technologies have enabled the effective consolidation of heterogeneous applications in a shared cloud infrastructure. Novel research challenges arising from this new shared environment include load balancing, workload estimation, resource isolation, machine replication, live migration, and an emergent need of automation to handle large scale operations with minimal manual intervention. Given that databases are at the core of most applications that are deployed in the cloud, database management systems (DBMSs) represent a very important technology component that needs to be virtualized in order to realize the benefits of virtualization from autonomic management of data-intensive applications in large scale data-centers. The goal of this tutorial is to survey the techniques used in providing elasticity in virtual machine systems, shared storage systems, and survey database research on multitenant architectures and elasticity primitives. This foundation of core Database as a Service advances, together with a primer of important related topics in OS and storage-level virtualization, are central for anyone that wants to operate in this area of research.

Sandboxing and Virtualization: Modern Tools for Combating Malware

Malware is probably the most significant computer security threat to enterprises and businesses alike. To address the exposure gap left by antivirus products, an emerging category of desktop security products that use application-level sandboxing attempts to address malware threats by containing their malicious behavior. High profile applications that now employ sandboxing include the Google Chrome browser, Internet Explorer Protect Mode, and Adobe Reader X. Partial virtualization techniques usually involve a combination of privilege restrictions by user ac counts and a virtual file system. Other terms for this approach include lightweight virtualiza tion, OS virtualization, process virtualization, and process confinement. Full virtualization techniquesare also called hardware virtu alization because the hardware layer and resources, including de vice drivers, are virtualized for a "guest" OS by a hypervisor layer.Utilizing hardware virtualization based techniques, a malware pro tection solution runs the target application in its own OS in a virtual machine.

Towards the Future Internet: virtual networks for convergent services

In this paper we will investigate the deficiencies and the achievements of today's Internet. We outline how Network Virtualization (NV) can overcome the shortfalls of today's networks, how it paves the way for the Future Internet, and how it can facilitate the convergence of currently different networks. The major building blocks of NV are the a) use of application-specific routing overlays, b) the safe consolidation of resources by OS virtualization on a generic infrastructure, and c) the exploitation of the network diversity for performance enhancements and for new business models, such as the provisioning of intermediates nodes or path oracles. Furthermore, we detail a more elaborate concept for network virtualization, which is denoted as Transport Virtualization (TV). TV transfers the concept of location independence of resources to the area of data transport in communication networks.
