This document outlines the security measures implemented in the InvestPro investment platform.

• Implementation: JWT-based stateless authentication
• Token Expiration: 7 days (configurable)
• Storage: localStorage (frontend)
• Transmission: Authorization header (Bearer <token>)

• Hashing: bcrypt with 10 salt rounds (12+ recommended in production)
• Requirements: Minimum 6 characters (enforce stronger requirements in production)
• Comparison: Constant-time comparison to prevent timing attacks

• Middleware: auth.js middleware protects all authenticated routes
• Scope: Each user can only access their own data
• Role-based: Ready for role implementation

• Configuration: Origin whitelist in environment variables
• Methods: GET, POST, PUT, DELETE
• Credentials: Supported

Implements security headers:

• Content-Security-Policy
• X-Frame-Options
• X-Content-Type-Options
• X-XSS-Protection
• Strict-Transport-Security

• Library: express-validator
• Coverage: Email format, password strength, data types
• Sanitization: Input trimming and normalization

const limiter = rateLimit({
  windowMs: 15 * 60 * 1000,
  max: 100
})

• Encryption: MongoDB supports encryption at rest
• Access Control: Strong credentials required
• Backups: Regular backups recommended
• Connection: TLS/SSL encryption over network

• Passwords: Never logged or exposed
• Tokens: Transmitted only via HTTPS
• API Keys: Stored in environment variables

• React's automatic escaping of content
• CSP headers from backend
• Sanitized API responses

• SameSite cookie policy
• Token-based CSRF (recommended for stateful apps)

• HTTPS required in production
• Secure localStorage usage
• No sensitive data in localStorage (only tokens)

All sensitive data stored in .env:

JWT_SECRET
MONGODB_URI
API_KEYS
CORS_ORIGIN

• Use HTTPS/TLS
• Network firewall
• DDoS protection
• WAF (Web Application Firewall)

• Use .env for secrets
• Validate all inputs
• Escape all outputs
• Use HTTPS everywhere
• Implement CORS correctly

• Penetration testing
• Vulnerability scanning
• Security code review
• Dependency audits

• Enable HTTPS
• Use strong JWT secret
• Increase bcrypt rounds to 12+
• Enable database authentication
• Implement rate limiting
• Set up logging and monitoring
• Enable 2FA
• Regular security audits
• Incident response plan

• GDPR ready (implement data retention policies)
• Privacy policy required
• Data deletion mechanism

• Secure password policy
• Session management
• Account lockout after failed attempts
