What are the differences between CSP and other security models?

CSP, or Content Security Policy, is primarily focused on preventing cross-site scripting (XSS) attacks by controlling resources the user agent is allowed to load. Other security models, like CORS (Cross-Origin Resource Sharing), focus on resource sharing between different origins. Would you like to know more about how CSP works?

Yes, how does CSP actually prevent XSS?

CSP prevents XSS by allowing developers to specify which sources of content are trusted. By defining a policy, you can restrict scripts, styles, and other resources to only load from specified domains, thus blocking malicious scripts from executing.

Are there any limitations to using CSP?

Yes, CSP can be complex to implement and may break existing functionality if not configured correctly. Additionally, it requires ongoing maintenance as your application evolves.

How does CSP compare to other security measures?

CSP is a powerful tool for mitigating XSS, but it should be used in conjunction with other security measures like input validation, secure coding practices, and regular security audits for comprehensive protection.
