What are the differences between CSP and other security protocols?

CSP, or Content Security Policy, is a security feature that helps prevent various attacks like XSS. It differs from other protocols like CORS, which controls resource sharing, and HTTPS, which encrypts data in transit.

Can you explain how CSP helps prevent XSS attacks?

CSP mitigates XSS by allowing you to specify which sources of content are trusted. If a script is loaded from an untrusted source, it will be blocked.

What are some common directives used in CSP?

Common directives include 'default-src', 'script-src', and 'style-src'. Each directive controls where content can be loaded from.

How does CSP compare to CORS?

CSP is focused on preventing content injection attacks, while CORS is about allowing or restricting resource sharing between different origins.

Are there any drawbacks to using CSP?

Yes, implementing CSP can be complex and may require extensive testing to ensure that legitimate content is not blocked.
