Content Security Policy: Your Website's Unsung Hero
SMRTR summary
Content Security Policy (CSP) is a web security feature that acts as a browser firewall, protecting against cross-site scripting (XSS) attacks by controlling webpage resource loading. CSP uses directives like default-src, script-src, and style-src to whitelist trusted content sources.
Best practices include starting with default-src 'self', testing in report-only mode, and avoiding unsafe options. Implementing CSP reduces a website's attack surface and enhances user protection against malicious content.
