It is safe to assume that web applications come with security vulnerabilities that make them vulnerable to hackers. Research shows that in most cases cross-site scripting (CSS) is at fault, so it is important that you have a protection mechanism that will protect your application from this type of attack.
Similarly, SQL injection and cookie poisoning are other possible attacks. Given the growing scale of these and similar attacks, you need a tool or strategy that would protect your web applications, and that’s where a specialized firewall will help.
A Web Application Firewall (WAF) is a service that protects your web applications from many application-level attacks like XSS and cookie poisoning.
