1498 Implementation D190b0bf

Implementation Guide

1. Collect the target URL/domain and environment context (CDN/proxy, redirects).
2. Fetch response headers (HTTP/HTTPS) and capture redirects/cookies.
3. Compare headers to recommended baselines and score gaps.
4. Provide concrete remediation steps and verify fixes.

1. Domain Input Phase

Accept domain specification:

• Full URL with protocol (https://example.com)
• Domain name only (example.com - will test HTTPS first)
• Multiple domains for batch analysis
• Specific paths for header variation testing

2. Header Fetching Phase

Retrieve HTTP response headers:

• Make HEAD or GET request to target
• Capture all security-relevant headers
• Test both HTTP and HTTPS responses
• Record redirect chains and final destination

3. Analysis Phase

Evaluate each security header against best practices:

Critical Headers:

• Strict-Transport-Security (HSTS)
• Content-Security-Policy (CSP)
• X-Frame-Options
• X-Content-Type-Options
• Permissions-Policy

Important Headers:

• Referrer-Policy
• Cross-Origin-Embedder-Policy (COEP)
• Cross-Origin-Opener-Policy (COOP)
• Cross-Origin-Resource-Policy (CORP)

Additional Checks:

• Server header information disclosure
• X-Powered-By header exposure
• Cookie security attributes (Secure, HttpOnly, SameSite)

4. Grading Phase

Calculate security score:

• A+ (95-100): All critical headers properly configured
• A (85-94): Critical headers present, minor issues
• B (75-84): Most headers present, some weaknesses
• C (65-74): Missing critical headers
• D (50-64): Significant security gaps
• F (<50): Multiple critical vulnerabilities

5. Report Generation Phase

Create comprehensive report with:

• Overall security grade and numeric score
• Missing headers with impact assessment
• Misconfigured headers with specific issues
• Remediation recommendations with examples
• Priority ranking for fixes
