Positive security model based server-side solution for prevention of cross-site scripting attacks

The latest advancements in the internet and communication technology has made day-to-day life fully dependent on web applications as all the facilities are available at just one click. Network failure, data breaches, computer viruses and other malicious contents based Cyber-attacks have affected the security of Web applications and there is always a risk of information stealing or tampering. Cross-site scripting is one of the application layer vulnerabilities that targets web applications by embedding scripts in a web page that will get executed at client side or server-side and the attacker will manipulate the information in desired manner. This paper provides a `Positive Security Model´ based server-side solution to prevent web applications and its users from XSS and provides flexibility to be integrated at any stage of development.
