Architecting Defense-in-Depth Web Security with Content-Security-Policy

Cross-Site Scripting (XSS) remains among the most common vulnerabilities on the modern web, allowing attackers to hijack sessions and exfiltrate customer credentials.

Configure granular script-src, style-src, connect-src, and frame-ancestors directives to construct an impenetrable browser boundary.

Frequently Asked Questions

Why is Content-Security-Policy critical for web applications?

CSP prevents Cross-Site Scripting (XSS), clickjacking, and packet sniffing by declaring which script sources, styles, fonts, and API connections are permitted to execute.

What is the difference between CSP and CSP-Report-Only?

Content-Security-Policy enforces restrictions and blocks violations. Content-Security-Policy-Report-Only monitors and logs violations without breaking site functionality, ideal for testing staging environments.
