🔐 Security Implementation (A+)

Defense in Depth Architecture

Layer 1: Input Protection

• XSS Prevention: HTML entity encoding, CSP headers
• SSRF Prevention: URL validation with protocol whitelisting
• Path Traversal: File path sanitization and validation
• SQL Injection: Parameterized query patterns
• Command Injection: Input validation and sanitization

// Example: Input sanitization
const safeInput = sanitizeInput(userInput);
// Output: <script> becomes harmless text

Layer 2: Authentication & Authorization

• JWT Validation: Format validation with base64url checking
• Token Generation: Cryptographically secure random tokens
• Password Strength: Complexity validation (8+ chars, mixed case, numbers, symbols)
• Secure Comparison: Timing attack prevention

// Example: Password validation
const result = validatePasswordStrength('MyP@ssw0rd');
// Returns: { isValid: true, score: 5, feedback: [] }

Layer 3: Rate Limiting & DoS Protection

• Client-side Rate Limiter: Configurable requests per time window
• Circuit Breaker: Automatic failure detection and recovery
• Request Throttling: Prevent API abuse

// Example: Rate limiting
const limiter = new RateLimiter(100, 60000); // 100 req/min
if (limiter.allowRequest()) {
  // Process request
}

Layer 4: Communication Security

• WebSocket Security: WSS (Secure WebSocket) with authentication
• Auto-Reconnection: Exponential backoff (max 30s)
• Circuit Breaker: 5 failures → open, 60s timeout
• Heartbeat: Keep-alive every 30s

// Example: MCP Client with circuit breaker
const client = new MCPClient({ url: 'wss://server.com' });
await client.connect(); // Automatically manages circuit breaker

Layer 5: Data Protection

• Sensitive Data Redaction: Automatic in logs
• JSON Depth Validation: DoS prevention
• XSS Pattern Detection: Multiple pattern matching
• Safe HTML Sanitization: Whitelist approach

// Example: Data redaction
logger.info('User login', { username: 'john', password: 'secret' });
// Logs: { username: 'john', password: '[REDACTED]' }

Security Headers (Nginx)

X-Frame-Options: SAMEORIGIN
X-Content-Type-Options: nosniff
X-XSS-Protection: 1; mode=block
Content-Security-Policy: (strict policy)
Strict-Transport-Security: max-age=31536000
Permissions-Policy: (restricted)

CodeQL Security Scan
