CSP Migration Checklist

Audit current resource usage
Implement CSP in report-only mode
Analyze violation reports for 2-4 weeks
Refactor code to eliminate 'unsafe-inline'
Implement nonce or hash-based approach
Test with real user traffic
Monitor performance impact
Deploy enforcing policy gradually
Set up ongoing monitoring
Document policy for team reference

Content-Security-Policy represents a paradigm shift in web security, moving from reactive patching to proactive prevention. While implementation requires effort and ongoing maintenance, the security benefits far outweigh the costs. A well-implemented CSP can prevent most XSS attacks, significantly reducing your application's attack surface and protecting your users from malicious code execution.## X-Frame-Options and Preventing Clickjacking Attacks

Clickjacking represents one of the most deceptive attack vectors in web security, where malicious actors trick users into clicking on something different from what they perceive. The X-Frame-Options header serves as a crucial defense mechanism against these attacks by controlling whether your website can be embedded within frames, iframes, or objects. Understanding and implementing this header correctly can prevent attackers from overlaying your legitimate site with malicious content.
