Study of Cross-Site Scripting Attacks and Their Countermeasures

Abstract

In present-day time, most of the associations are making use of web services for improved services to their clients. With the upturn in count of web users, there is a considerable hike in the web attacks. Thus, security becomes the dominant matter in web applications. The disparate kind of vulnerabilities resulted in the disparate types of attacks. The attackers may take benefit of these vulnerabilities and can misuse the data in the database. Study indicates that more than 80% of the web applications are vulnerable to cross-site scripting (XSS) attacks. XSS is one of the fatal attacks & it has been practiced over the maximum number of well-known search engines and social sites. In this paper, we have considered XSS attacks, its types and different methods employed to resist these attacks with their corresponding limitations. Additionally, we have discussed the proposed approach for countering XSS attack and how this approach is superior to others.
