Analysis Of Virtualization Issues And Security Enhancement Strategies For Cloud Computing

Virtual Machine Security - Full Virtualization and Para Virtualization are two kinds of virtualization in a cloud computing paradigm. In full virtualization, entire hardware architecture is replicated virtually. However, in para virtualization, an operating system is modified so that it can be run concurrently with other operating systems. VMM Instance Isolation ensures that different instances running on the same physical machine are isolated from each other. However, current VMMs do not offer perfect isolation. Many bugs have been found in all popular VMMs that allow escaping from VM (Virtual machine). Vulnerabilities have been found in all virtualization software, which can be exploited by malicious users to bypass certain security restrictions or/and gain escalated privileges. ation software running on or being developed for cloud computing platforms presents different security challenges. It is depending on the delivery model of that particular platform. Flexibility, openness and public availability of cloud infrastructure are threats for application security. The existing vulnerabilities like Presence of trap doors, overflow problems, poor quality code etc. are threats for various attacks. Multi-tenant environment of cloud platforms, the lack of direct control over the environment, and access to data by the cloud platform vendor; are the key issues for using a cloud application. Preserving integrity of applications being executed in remote machines is an open

The extensive use of virtualization in implementing cloud infrastructure brings unique security concerns for customers or tenants of a public cloud service. Virtualization alters the relationship between the OS and underlying hardware - be it computing, storage or even networking. This introduces an additional layer -

The economic case for cloud computing is compelling and at the same time there are striking challenges in its security. The concepts of cloud computing security issues are fundamentally new and intractable. What appears new is only relative to traditional computing that has been practiced since several years. Many such security problems have been giving attention since the time-sharing era. Cloud computing providers have and can build datacenters as large due to their expertise in organizing and provisioning computational resources at as low cost as possible.

According to Prasad, Gyani and Murti (2012), “Cloud computing can be defined as a new style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet” (p.7). This statement is from five years ago, and although cloud computing is no longer considered new, this definition still describes what cloud computing means today. Cloud computing being private or public is becoming more primordial in the IT sector due to the numerous advantages it gives to its end users (Basmadjian et al. 2012). Since the interest in cloud computing keeps on increasing, efforts need to continue to evaluate current trends in security and privacy. Cloud computing

The main issue that slows down the growth of cloud computing is security. No matter how many security management tools are released or assurances of reliability are made, complications with data privacy and data protection continue to plague the market. Covering all potential security issues in this article is simply impossible. This is because of the fact that we 're still discovering many of the security issues which challenges cloud computing as it is still a work-in-progress. Cloud Computing is rapidly evolving and hence what we see today may quickly become irrelevant.

A common pitfall in cloud security is the temptation to deploy the same security solutions for dedicated physical servers and endpoints to virtual machines in data centres and in the cloud. This article explains the trouble with virtual security and why, if you’re still relying on traditional security methods, you might be at risk.

In this paper, the authors survey many sources and literature on cloud security issues, namely vulnerabilities, threats, and attacks. A total of 504 articles were look at to gather the data used in this paper. While the authors use this number to say that the research trend is up on mitigating security risks, they also suggest that security is the main priority of most research to the detriment of other areas. They offer no concrete numbers to back up this claim..

Cloud computing is steadily increasing as a viable enterprise technology solution. Information technology literature reports an expected boost in enterprise adoption of cloud computing in the next few years. Business plans to transition operations to cloud computing are also commonly reported. Despite these trends, there are many businesses that remain skeptical of the benefits of cloud computing and continue to support information systems in an on-site location. Careful planning and due diligence is essential to ensure that the most beneficial cloud computing model is utilized to meet business needs. This use case explores cloud computing methods, reviews security concerns regarding virtualization, and considers mechanisms to better

Cloud computing is revolutionizing many ecosystems by providing organizations with computing resources featuring easy deployment, connectivity, configuration, automation and scalability. This paradigm shift raises a broad range of security and privacy issues that must be taken into consideration. Loss of control, and trust are key challenges in cloud computing environments. This paper will be describing and focusing on cloud security and privacy. In addition to cloud security, the general model of cloud computing is also described where the cloud security and privacy issues can be approached. To preserve such issues, some propositions for cloud security for reference are also proposed along with a brief description for deployment in cloud computing.

By introducing the intense programming which were extremely difficult to hack the servers move toward becoming more secure however it includes certain financial costs furthermore for the organizations which were eager to upgrade to such security components. Centralization is likewise one more factor that makes the cloud innovation the most secure one as it guarantees the simple control particularly to the customers of PaaS and IaaS models. Cloud security is centered around the single area on the primary server which is much better than the idea of individual organizations controlling the security of various servers at various areas. Through cloud security better treatment of the framework in a sheltered and secure way is accomplished. In organizations, if business is coordinated with the cloud administrations they may confront bring down dangers and enhance responsibility and kept up since the cloud specialist co-op is in charge of taking care of the whole thing. Therefore, the business require not to have money related incurrence and due to this reason it is important to pick the most committed organization to give the administrations, further developed safety efforts should have been actualized. The organizations in a need to guarantee development via completing the profound examination with respect to the

Cloud technologies revolve heavily around virtual machines that reside on physical servers (Talbot, 2009). One physical server could be the home of a slew of virtual machines; should an attacker interrupt the normal operations of a physical server it could result in the inoperability of the virtual machines also. One of the techniques can be used is an attacker implanting a virtual machine on a physical server (Talbot, 2009). Once the

Cloud Computing is a process of delivering a companies or individual’s applications and documents from any place, at any time, on any device. It is also a process in which hosted services are delivered through the internet.

Cloud Computing is an advanced paradigm with a lot of advantages, but its distinct features also create privacy and security issues. Cloud computing provides service model which is more efficient technology for business support. Cloud computing is in fact a service based approach which has changed almost every aspect of computing technologies. There are many threats to the cloud computing including security vulnerabilities and privacy issues.
