Threats to Virtual Environment in Cloud and their Preventive Measures

Abstract

The evolution of technology has changed the way human interacts. From the era of newlinemainframe computers to client-server technology along with the advent of the newlineinternet, the technological shift proves to be a game changer for the world. Cloud newlineComputing is one of the technologies contributing to making people s life easier and newlinebetter. It combines the outstanding features of previous technologies like the newlinemainframe era or client-server era followed by the Internet era and creates a network newlineof computers that is stretched across the globe using distributed technology. It newlineprevents the organization from investing millions in the procurement of the hardware newlineand spending more than a million on maintaining them. Basically, Cloud Computing newlinerefers to the efficient use of shared resources among the applications that are hosted newlineon the Internet. newlineBased on the type of services the Cloud offers, it is mainly categorized as newlineInfrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-aService (SaaS). Cloud Computing offers countless benefits like on-demand purchase, newlineeasy maintenance, improved performance, mobility, device independence, and newlineflexible configuration. Despite all the advantages, Cloud security is still a big concern newlinefor Cloud users. There are many threats to the Cloud environment which include newlinepassword cracking, man-in-the-middle attack, denial of service attacks, phishing newlineattacks, spoofing, SQL injection attack, cross-site attack, malware attack, HTTP flood newlineattacks, ransomware, and so on. The intruders are finding new ways to harm the newlinecredibility of the Cloud. So, Cloud developers and researchers need to be one step ahead of them and continue working on improving Cloud security. .. newline
