This document outlines the comprehensive security measures implemented in the [RE]Print Studios client portal system.

• JWT Token Authentication: Secure token-based authentication with refresh tokens
• Role-Based Access Control (RBAC): Separate admin and client roles with appropriate permissions
• Session Management: Secure session handling with automatic token refresh
• Password Security: BCrypt hashing with salt rounds, enforced password complexity
• Authentication Persistence: Tokens persist across page refreshes using multiple storage mechanisms

• Centralized Validation: Comprehensive validation middleware using express-validator
• XSS Prevention: HTML sanitization using XSS library to prevent script injection
• SQL Injection Prevention: Parameterized queries and SQL pattern detection
• Path Traversal Prevention: File path validation and sanitization
• Command Injection Prevention: Input validation to prevent command execution
• NoSQL Injection Prevention: MongoDB sanitization middleware (future-proofing)

• Tiered Rate Limiting: Different limits for different endpoint types:
  • Authentication endpoints: 5 requests per 15 minutes
  • API endpoints: 100 requests per 15 minutes
  • File uploads: 20 requests per 15 minutes
• IP-based limiting: Per-IP address rate limiting
• Successful request skipping: Failed attempts don't count against successful ones

• Content Security Policy (CSP): Restricts resource loading to prevent XSS
• HSTS: HTTP Strict Transport Security for HTTPS enforcement
• X-Frame-Options: Prevents clickjacking attacks
• X-Content-Type-Options: Prevents MIME type sniffing
• Referrer Policy: Controls referrer information disclosure

• Request Size Limits: Configurable limits for JSON, URL-encoded, and file uploads
• File Type Validation: Whitelist of allowed file extensions
• Filename Sanitization: Prevents malicious filename attacks
• Sensitive Data Exclusion: Passwords and tokens excluded from logs and error messages

• Comprehensive Logging: All authentication and sensitive operations logged
• Request Tracking: IP addresses, user agents, and timestamps recorded
• Error Monitoring: Failed attempts and security violations tracked
• Performance Metrics: Response times and duration monitoring

• CORS Configuration: Properly configured cross-origin resource sharing
• JWT Validation: Comprehensive token validation and verification
• Endpoint Protection: All sensitive endpoints require authentication
• Error Handling: Consistent error responses without information disclosure
