## 🔐 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 `.env` files to version control, especially `.env.production` which contains production credentials
|
|
- Use `.env.example` as 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 `.env` files to `.gitignore` to 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

|
- [ ] Set up monitoring and logging
|
|
|
|
#### **Regular Security Tasks**

|
- [ ] Rotate credentials monthly
|
|
- [ ] Update dependencies regularly
|
|
- [ ] Monitor logs for suspicious activity
|
|
- [ ] Backup databases securely
