Which is the best way to protect against XSS?
Stored XSS attack prevention/mitigation A web application firewall (WAF) is the most commonly used solution for protection from XSS and web application attacks. WAFs employ different methods to counter attack vectors. In the case of XSS, most will rely on signature based filtering to identify and block malicious requests.
How is XSS different from other web attacks?
XSS differs from other web attack vectors (e.g., SQL injections ), in that it does not directly target the application itself. Instead, the users of the web application are the ones at risk. A successful cross site scripting attack can have devastating consequences for an online business’s reputation and its relationship with its clients.
What’s the difference between stored XSS and reflected XSS?
While stored XSS payloads are stored on the target server for a later response, reflected XSS payloads are not stored on the target server. Instead, reflected XSS payloads, such as an injected URL, are delivered to the user through phishing emails, social media posts, and more.
