Humanet implements comprehensive security measures to protect against common web application vulnerabilities and ensure data integrity.

• Window: 15 minutes
• Limit: 100 requests per IP
• Purpose: Prevent DoS attacks and abuse

• Window: 15 minutes
• Limit: 5 attempts per IP
• Purpose: Prevent brute force attacks
• Features:

# Rate Limiting
RATE_LIMIT_WINDOW_MS=900000
RATE_LIMIT_MAX_REQUESTS=100
AUTH_RATE_LIMIT_MAX=5
ENABLE_RATE_LIMITING=true

# Security Headers
ENABLE_SECURITY_HEADERS=true
ENABLE_CORS=true
TRUST_PROXY=true

# CORS Origins (comma-separated)
CORS_ALLOWED_ORIGINS=http://localhost:3000,https://myapp.com

# Monitoring
LOG_SECURITY_EVENTS=true
BLOCK_SUSPICIOUS_IPS=false

1. Enable HTTPS

   • Use SSL/TLS certificates
   • Redirect HTTP to HTTPS
   • Set TRUST_PROXY=true behind load balancers

2. Database Security

   • Use MongoDB authentication
   • Enable database encryption
   • Restrict network access

3. API Keys (Future Implementation)

   • Implement API key validation
   • Rate limit by API key
   • Monitor API usage

4. Monitoring & Alerting

   • Set up log aggregation
   • Monitor failed requests
   • Alert on suspicious patterns

# Install security audit tools
npm audit

# Check for vulnerabilities
pnpm audit

# Use security linting
npx eslint --ext .ts src/ --config .eslintrc.security.js

1. Rate Limiting: Test with multiple rapid requests
2. Input Validation: Test with malicious payloads
3. Authentication: Test with invalid credentials
4. CORS: Test with unauthorized origins

1. Check logs for patterns
2. Identify source IP addresses
3. Temporary IP blocking if needed
4. Scale rate limits if legitimate traffic

1. Monitor failed login attempts
2. Implement progressive delays
3. Notify users of suspicious activity
4. Consider CAPTCHA implementation

1. Update validation schemas
2. Patch security middleware
3. Review input sanitization
4. Update security tests

• Rate limiting configured and tested
• Security headers implemented
• Input validation on all endpoints
• CORS properly configured
• Authentication properly secured
• Logging and monitoring enabled
• SSL/TLS certificates installed
• Database access restricted
• Regular security audits scheduled
• Incident response plan documented

1. Injection: Input validation & sanitization ✅
2. Broken Authentication: Secure JWT implementation ✅
3. Sensitive Data Exposure: HTTPS & secure headers ✅
4. XML External Entities: Not applicable (no XML) ✅
5. Broken Access Control: Role-based authorization ✅
6. Security Misconfiguration: Secure defaults ✅
7. Cross-Site Scripting: CSP headers & validation ✅
8. Insecure Deserialization: JSON only, validated ✅
9. Known Vulnerabilities: Regular audits ✅
