Content Security Policy (CSP) is enforced by

Question

BlackTom AI · Accepted Answer

The question asks about which component enforces Content Security Policy (CSP).
Option 1: 'Apache/NodeJS/Nginx' — While these servers can send CSP headers (like Content-Security-Policy) to instruct the browser what to enforce, the actual enforcement of those policies is performed by the client-side environment, not by the server software itself. So this option is inaccurate as a description of who enforces CSP.
Option 2: 'Operating Systems' — An OS is responsible for low-level resource management and security features, but CSP enforcement is not part of the OS's security model. CSP operates at a higher level, within web browsers, making this option incorrect.
Option 3: 'Mainstream Web Browsers' — True in terms of enforcement. Browsers read CSP headers or meta tags and apply the policy to block or allow resources and scripts. This is the standard mechanism by which CSP is enforced.
Option 4: 'Internet Service Provider' — ISPs may implement various network protections or filtering, but CSP enforcement is not within their remit. They do not enforce policies about which scripts or resources a page can load in the browser, so this option is not correct.
