Security in cloud computing is a major concern. In fact, cloud computing is an extend of Grid Computing, Distributed Computing and Parallel Computing. [1] In the current era, It is a wide field. Moreover, virtualization technologies provide a virtual environment for not only executing applications but also for storage, memory, and networking. requirement for cloud environments is not only the GUIDE TO SECURITY FOR FULL VIRTUALIZATION TECHNOLOGIES ES-1 Executive Summary Virtualization is the simulation of the software and/or hardware upon which other software runs. In this chapter, we describe the different virtualization types and the security issues in cloud virtualization components such as hypervisor, virtual machines and guest disk images. Computer Science Department, Amity University, India. In Cloud computing, virtualization … why the local cloud is becoming very popular. there are risks associated with this technology. Importance of Virtualization in Cloud Computing Cloud can exist without Virtualization, although it will be difficult and inefficient. Here we introduce an approach called duplication method which allows the users to create more number of same virtual resources, so that if one of the resources fail due to some reason, users may have some more same resources to continue without disturbing their work and provide the security at different levels to make Virtual resources secure. Indonesian Journal of Electrical Engineering and Computer Science. Security Concerns when using Virtualization in Cloud Computing. Cloud makes notion of “Pay for what you use”, “infinite availability- use as much you want”. Server virtualization. Also, it provides flexibility in the used platform. Specifically, we propose the structuring of the virtualization security management system and the management method to reduce the complexity of administering the virtual machines installed in the cloud data centers caused by the inherent properties of virtual machines characterized by dynamic changes in the form of image files. Cloud security management for software-as-a-service (SaaS) In our latest study of cloud application use, we found that on average, organizations are using 1,427 distinct cloud applications1—most of which are software-as-a-service (SaaS) applications, such as Microsoft Office 365, Box, and many other productivity apps that employees sign up for, often without IT approval. In other words, Virtualization is a technique, which allows to share a single physical instance of a resource or an application among multiple customers and organizations. Cloud Computing Definition “Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction. Therefore, virtualization can be used to improve security in a cloud computing environment. The move to the cloud shows no signs of slowing down, and cloud security products will need to continue to keep up with demand.

Cloud computing is a hot trend. INTRODUCTION Cloud computing is a network-based environment that focuses on sharing computations and resources. Using virtual machines complicates IT security in a big way for both companies running private cloud computing and service providers. For example, the Xen hypervisor discussed in Section 10.5 has approximately 60 000 lines of code while the Denali hypervisor [522] has only about half, 30 000 lines of code. 6.

When the, Network Virtualization offers a solution for Future Internet and it is a key enabler for cloud computing applications. Serverless computing, the dynamic allocation of cloud compute resources to run customer code, is built upon either virtualization or containerization, depending on the cloud service. The recent advances in network virtualization gave cloud operators the ability to extend their cloud computing offerings with virtual networks. To restrict client from accessing the shared data directly, proxy and brokerage services should be employed. Analysis”, International Journal of research in Computer Engineering and Electronics, 2013. In such cloud computing environments, issues of malicious codes, hacking and leak of confidential information are the biggest concerns of the people involved.

The term virtualization is often synonymous with hardware virtualization, which plays a fundamental role in efficiently delivering Infrastructure-as-a-Service (IaaS) solutions for cloud computing. Although the cloud computing vendors ensure more secure password protected accounts, any sign of security This white paper provides guidance on the identification and management of security risks specific to compute virtualization technologies that run on server hardware—as opposed to, for example, desktop, network, or storage virtualization. Cloud computing, virtualization security technology, attack principle. Since data management and infrastructure management in cloud is provided by third-party, it is always a risk to handover the sensitive information to such providers. Several performance metrics are employed in order to evaluate the efficiency of specific VNE approaches.
