Security Guide
🔐 Security Best Practices for Medication Reminder App
Password Security
Password Requirements
- Minimum 8 characters
- Must contain uppercase and lowercase letters
- Must contain at least one number
- Must contain at least one special character
- Cannot be common passwords (password123, admin, etc.)
Password Hashing
- Uses bcrypt with salt rounds for secure password storage
- Passwords are never stored in plain text
- Password verification happens through secure hash comparison
Authentication Security
Session Management
- JWT-like token system for user sessions
- Tokens have expiration times
- Secure token storage and transmission
- Automatic session cleanup on logout
Email Verification
- All new accounts require email verification
- Verification tokens are time-limited
- Prevents unauthorized account creation
- Uses cryptographically secure random tokens
OAuth Security
- Supports Google and GitHub OAuth
- Secure OAuth flow implementation
- No password storage for OAuth users
- Account linking prevention for security
Environment Security
Environment Variables
- Never commit
.envfiles to version control, especially.env.productionwhich contains production credentials - Use
.env.exampleas a template for creating new environment files - Create separate environment files for different deployment environments:
.env- Local development.env.staging- Staging environment.env.production- Production environment
- Always add all
.envfiles to.gitignoreto prevent accidental commits - Use environment variables for configuration to maintain security and flexibility
- Rotate credentials regularly and use strong, unique passwords for each environment
- Consider using a secrets management system for production environments
- Never hardcode sensitive information in source code
Docker Security
- Non-root user for application execution
- Multi-stage builds to minimize attack surface
- Health checks for service monitoring
- Isolated network for services
Database Security
CouchDB Security
- Admin authentication required
- Database-level access control
- SSL/TLS encryption for production
- Regular backup and security updates
Data Protection
- User data isolation by user ID
- Input validation and sanitization
- Protection against injection attacks
- Secure data deletion capabilities
Production Security Checklist
Before Deployment
- Change default admin password
- Configure strong CouchDB credentials
- Set up Mailgun with proper API keys
- Enable SSL/TLS certificates
- Configure firewall rules
- Set up monitoring and logging
Regular Security Tasks
- Rotate credentials monthly
- Update dependencies regularly
- Monitor logs for suspicious activity
- Backup databases securely
- Review user access permissions
- Test disaster recovery procedures
Incident Response
Security Breach Protocol
-
Immediate Response

- Change all credentials
- Review access logs
- Document the incident
-
Investigation
- Identify breach source
- Assess data exposure
- Notify affected users
- Implement fixes
-
Recovery

Healthcare Compliance
- HIPAA considerations for health data
- Secure medication information handling
- Audit trail capabilities
- Data retention policies
Security Monitoring
Logging
- Authentication attempts
