Mitigation of Cross-Site Scripting Attacks in Mobile Cloud Environments

Abstract

Cross-Site Scripting (XSS) is one of the dangerous and topmost web attacks as stated by recent surveys. XSS vulnerability arises, when an application deployed in a cloud, accept information from uncertain origin without an input validation, allowing the execution of dynamic content. XSS vulnerabilities may cause serious security violations in web and mobile cloud-based applications. In general, Cross-Site Scripting bugs are very easy to accomplish, but hard to discover and mitigate, because of the flexibility of encoding schemes like HTML encoding, which offers the adversary numerous chances to bypass the filters that should block dangerous content from being inserted into relied websites. In order to mitigate XSS vulnerability of a web application in the mobile cloud, a novel approach is presented, which successfully identifies the JavaScript-driven XSS attacks. In addition, we focus on, initiating a client-side Cross-Site Scripting attack discovery and mitigation technique known as Secure XSS layer based on the placement of sanitizers in the inserted malicious code.
