Security Best Practices
Secure development is critical to modern applications architecture. This guide outlines essential security strategies and implementation patterns for robust protection of your systems.
1. Input Validation
Validation Framework
Use schema-based validation to sanitize all user inputs and API requests.
const validate = require('@mnnx/validator');
const cleanInput = validate(formData, {
username: { type: 'string', maxLength: 20 },
email: { type: 'email' }
});
Protection
Prevent XSS and injection attacks by escaping special characters.
const sanitize = require('xss');
const safeHTML = sanitize(userInput);
2. Authentication
- Require multifactor authentication for all production systems
- Use hardware tokens or authenticator apps for sensitive operations
- Implement account lockout mechanisms after 5 consecutive failed attempts
3. Data Protection
Encryption
- Use 256-bit AES encryption at rest
- Implement TLS 1.3 for all data in transit
- Store cryptographic keys in secure HSM modules
Access Control
Enforce least-privilege principles with role-based access controls and regular audits.
4. API Security
Best Practice: Rate Limiting
Implement per-user rate limits with sliding window strategies to prevent API abuse.
// mnnx rate limit middleware
app.use(mnnx.limits({
windowMs: 15 * 60 * 1000, // 15 minutes
max: 100 // limit each IP to 100 requests
}));
5. Error Handling
Security Tip
Never expose stack traces or internal error details to users - use generic error messages with developer-friendly logs for troubleshooting.
Security Summary
- Validate and sanitize all user input
- Use strong encryption algorithms for sensitive data
- Implement multi-factor authentication
- Monitor and log all system activity
- Regularly audit access permissions
