🔒 Security Overview

MCP-RS implements comprehensive security measures designed for production environments. Our security-first approach ensures safe operation with AI agents while maintaining high performance.

🛡️ Enterprise-Grade 5-Layer Security Architecture (86% Complete)

✅ Layer 1: Cryptographic Security

  • AES-GCM-256 Encryption: Military-grade authenticated encryption
  • PBKDF2 Key Derivation: 100,000 iterations for secure key generation
  • Secure Secret Management: Zero-copy secret handling with automatic cleanup
  • Cryptographic Randomness: Hardware-backed random number generation

✅ Layer 2: Network Security

  • TLS 1.2+ Enforcement: Mandatory secure transport layer
  • Certificate Validation: Strict certificate chain verification
  • HTTPS-Only Communication: Automatic HTTP to HTTPS redirection
  • Secure Headers: Content Security Policy and security headers enforcement

✅ Layer 3: Access Control & Rate Limiting

  • Token Bucket Rate Limiting: Advanced rate limiting with burst handling
  • Client Isolation: Independent rate limits per client IP
  • Configurable Thresholds: Customizable rate limiting parameters
  • Graceful Degradation: Smooth handling of rate limit violations

✅ Layer 4: Input Validation & Attack Prevention

  • SQL Injection Protection: 11 attack pattern detection algorithms
    • Union-based injection detection
    • Boolean-based blind injection prevention
    • Time-based injection monitoring
    • Error-based injection blocking
    • Stacked query prevention
  • Advanced Input Validation: Custom rule engine with real-time validation
  • HTML Sanitization: Safe HTML processing with whitelist filtering

✅ Layer 5: Application Security

  • Zero-Panic Operations: Complete elimination of panic-causing code
  • Result-Based Error Handling: Comprehensive error management system
  • Memory Safety: Rust’s ownership system prevents buffer overflows
  • Thread Safety: Async-safe operations with proper synchronization

🔐 Configuration Security

Secure Environment Variables

[handlers.wordpress]
# Secure variable expansion
url = "${WORDPRESS_URL}"
username = "${WORDPRESS_USERNAME}"
password = "${WORDPRESS_PASSWORD}"

Best Practices

  • Use WordPress Application Passwords (never plain passwords)
  • Implement proper environment variable naming conventions
  • Regular password rotation and access review
  • HTTPS-only connections for all WordPress API calls
