🔐 Security Overview

An introduction to security fundamentals in NestFlux applications.

🎯 Security Philosophy​

NestFlux implements a comprehensive security strategy built on industry best practices:

  • Defense in Depth: Multiple layers of security controls
  • Zero Trust: Never trust, always verify approach
  • Principle of Least Privilege: Users and systems get minimum necessary access
  • Security by Design: Security considerations integrated from the start

🛡️ Security Layers​

Application Security​

The NestFlux template includes several built-in security measures:

  • Helmet: HTTP security headers to protect against common vulnerabilities
  • Rate Limiting: Protection against brute force and DoS attacks
  • Input Validation: Comprehensive request validation using Zod schemas
  • CORS Configuration: Controlled cross-origin resource sharing
  • Environment Isolation: Secure handling of sensitive configuration

Identity & Access Management​

NestFlux implements modern identity management:

  • External Authentication: Integration with OIDC providers (Authentik, Keycloak)
  • Role-Based Access Control: Granular permission system
  • JWT Tokens: Secure, stateless authentication tokens
  • Session Management: Proper token lifecycle and refresh handling

Data Protection​

Data security is ensured through:

  • Database Security: Secure database connections and query protection
  • Encryption: Sensitive data encryption at rest and in transit
  • API Security: Protected endpoints with proper validation
  • Audit Logging: Comprehensive logging for security monitoring

🔍 Security Components​

Authentication​

How users prove their identity to access the system. NestFlux uses OIDC integration with third-party providers for secure, standards-based authentication.

Authorization​

How the system determines what authenticated users can access. NestFlux implements RBAC with fine-grained permissions for comprehensive access control.

🚨 Common Security Considerations​

Environment Variables​

  • Store sensitive configuration securely
  • Never commit secrets to version control
  • Use different keys for different environments
  • Rotate secrets regularly

API Security​

  • Validate all input data
  • Implement proper error handling
  • Use HTTPS in production
  • Monitor for suspicious activity

Database Security​

  • Use parameterized queries (Drizzle handles this)
  • Implement proper access controls
  • Regular security updates
  • Backup and recovery procedures

Security is an ongoing process, not a one-time setup. Regular reviews and updates are essential for maintaining a secure application.
