What is Content Security Policy in Cybersecurity?
Content Security Policy is an HTTP response header that tells browsers which sources of content (scripts, styles, images, frames) are permitted on a page. CSP mitigates cross-site scripting by preventing the browser from executing inline scripts or loading resources from unauthorized domains, even if an attacker injects malicious markup.
Why Content Security Policy Matters for Your Cybersecurity Career
CSP is a critical defense-in-depth control for web applications. Security engineers configure CSP headers to restrict script sources and block inline JavaScript. Penetration testers evaluate CSP policies for bypasses. A well-configured CSP can prevent exploitation of XSS vulnerabilities even when input validation fails.
