🏆 Enterprise-Grade Security Practices Implemented

🔐 Multi-Layer Authentication

IP whitelisting combined with credential-based login for admin access

🛡️ Defense in Depth

Multiple security layers including headers, file permissions, and access controls

🚦 Rate Limiting

Protection against brute force and DDoS attacks with intelligent rate limiting

📝 Security Logging

Comprehensive logging with protected log files for incident analysis

🔒 HTTPS Enforcement

Strict Transport Security with 6-month preload for all connections

⚡ Performance + Security

HTTP/2, GZIP compression, and caching without compromising security

⚙️ Technical Implementation Details

Access Control Mechanisms

  • IP-based access restriction for administrative interfaces
  • HTTP method validation (POST-only endpoints)
  • CSRF token validation on form submissions
  • Security key requirements for sensitive operations
  • File permission hardening (600 for config, 644 for public)

Content Security Policy (CSP)

  • Whitelisted sources for scripts, styles, and fonts
  • Restricted frame ancestors to prevent clickjacking
  • Controlled form actions to prevent data exfiltration
  • Object-src set to 'none' to prevent plugin exploitation
  • Base-uri restricted to prevent base tag injection

Third-Party Integration Security

  • Google Analytics with proper CSP configuration
  • Google Tag Manager with controlled script sources
  • Calendly integration with frame-src restrictions
  • CDN resources from trusted sources only
  • Connect-src limited to necessary API endpoints

Server Configuration

  • LiteSpeed web server with optimized settings
  • HTTP/2 and HTTP/3 (QUIC) protocol support
  • GZIP compression for optimal performance
  • Browser caching with appropriate cache-control headers
  • Server signature hiding for security through obscurity

🔍 Mozilla Observatory Analysis

Test Results: 8/10 Tests Passed

HTTPS Redirection PASSED
CORS Configuration PASSED
Referrer Policy PASSED
Strict Transport Security PASSED
X-Content-Type-Options PASSED
X-Frame-Options PASSED
Content Security Policy ACCEPTABLE (Analytics)
Subresource Integrity HTTPS Only

Note: CSP warnings are necessary for Google Analytics and third-party integrations. This is industry-standard practice and does not indicate a security vulnerability. Grade B (75/100) is excellent for production websites with analytics enabled.
