Analyzing Virtualization Vulnerabilities and Design a Secure Cloud Environment to Prevent from XSS Attack

Cloud virtualization has created an enormous impact on IT and networking worlds. A cloud environment is built on virtualization technology. Virtualization and its exclusive architecture have numerous features and advantages over non-conventional virtual machines. However, these new uniqueness create new vulnerabilities and attacks on a virtualization based cloud system. Cross Site Scripting (XSS) is among the top cloud vulnerabilities, according to recent studies. This exposure occurs when a user uses the input from a cloud environment application without properly looking into them. This allows an attacker to execute malicious scripts in cloud. The scripts execute harmful actions when a user visits the exploited cloud. Current approaches to mitigate this problem, especially on effective detection of XSS vulnerabilities in the application or prevention of real-time XSS attacks. To address this problem, the survey of different vulnerability attacks on cloud virtualization performed and also presents a concept for the removal of XSS vulnerabilities to secure the cloud environment.
