Security Measures

Getting Started

Data Encryption

Use HTTPS and enforce strong encryption standards for all data in motion. Store sensitive information using secure storage.

HTTPS: true
ENCRYPTION: AES-256-GCM

Authentication

Always implement multi-factor authentication and session-based security models for user authentication.

2FA_REQUIRED=true

Protection Layers

Threat Protection

Implement security headers and protect against:

XSS (Cross Site Scripting)
CSRF (Cross Site Request Forgery)
SQL Injections
Brute-force attacks (with rate limiting)

Rate Limiting

Apply rate limits per user to prevent abuse:

API_RATE_LIMIT=100
RPS_PER_IP=1000
COUNTRY_ALLOWLIST=US,EU

Customize limit based on IP, user, or request type.

Implementation Examples

Secure Headers

Content-Security-Policy:
    default-src 'none';
    script-src 'self';
    style-src 'self';
    img-src 'self';
    form-action 'self';
    base-uri 'self';
    upgrade-insecure-requests;

X-Content-Type-Options: nosniff
Strict-Transport-Security: max-age=63072000; includeSubDomains

Add these to all critical endpoints to prevent content spoofing.

Input Sanitization

// Node.js example
const cleanInput = userInput.replace(/[^\w\s]/gi, '');
const validatedParam = validateEmail(email);

Always validate and sanitize all inputs at the server level.

Recommended Security Measures

Use HTTPS with strong TLS protocols
Apply input validation to prevent injection attacks
Store secrets in secure environment variables
Enable content security policies
Regular security code audits
Daily security monitoring for vulnerabilities
