Data Protection Strategies

Code Sanitization

# ❌ DON'T: Send real credentials to AI
DATABASE_URL = "postgresql://user:[email protected]:5432/app"
API_KEY = "sk-1234567890abcdef"
SECRET_KEY = "super-secret-production-key"

# ✅ DO: Use placeholders when seeking AI help
DATABASE_URL = "postgresql://username:password@hostname:5432/database"
API_KEY = "your-api-key-here"
SECRET_KEY = "your-secret-key"

# ✅ BETTER: Use environment variables in examples
import os
DATABASE_URL = os.getenv('DATABASE_URL')
API_KEY = os.getenv('API_KEY')
SECRET_KEY = os.getenv('SECRET_KEY')

Sensitive Data Identification

# Automated scanning before AI submission
# Use tools like git-secrets, truffleHog, or custom scripts

# Example pre-commit hook
#!/bin/bash
# Check for potential secrets before committing
git diff --cached --name-only | xargs grep -l "password\|secret\|key\|token" && {
    echo "⚠️  Potential secrets detected. Review before AI submission."
    exit 1
}

# Pattern matching for common secret formats
grep -E "(sk-[a-zA-Z0-9]{32}|[A-Za-z0-9]{32})" staged_files.txt

Local Development Practices

Safe Development Workflow:

1. 🔒 Use local environment variables
   - .env files (never committed)
   - System environment variables
   - Secret management tools

2. 🧹 Clean code before AI interaction
   - Remove hardcoded credentials
   - Replace real URLs with examples
   - Sanitize business logic

3. 🔍 Review AI suggestions
   - Check for security vulnerabilities
   - Validate against security policies
   - Test for injection vulnerabilities

4. 🧪 Security testing
   - Static analysis tools
   - Dependency vulnerability scans
   - Manual security review
