  • • Sandboxed Execution: Code execution in isolated environment
  • • Access Controls: API key-based authentication
  • • Audit Logging: Request tracking for enterprise users

Important Privacy Considerations:

  • • Sensitive Data: Avoid including API keys, passwords, or personal information in prompts
  • • Corporate Data: Review company policies before using with proprietary code
  • • Local Processing: Some operations (file reading) happen locally before sending to API
  • • Data Retention: Google's data retention policies apply to all processed content

🔑API Key Management Best Practices

Secure API Key Setup
# Use environment variables (recommended)
export GEMINI_API_KEY="your-api-key"

# Or create a secure config file
mkdir -p ~/.local/etc
echo 'GEMINI_API_KEY="your-api-key"' > ~/.local/etc/.env
chmod 600 ~/.local/etc/.env

# Verify security
ls -la ~/.local/etc/.env
# Should show: -rw------- (owner read/write only)

Security Best Practices

  • • Rotate Keys Regularly: Generate new keys periodically
  • • Restrict Permissions: Use principle of least privilege
  • • Monitor Usage: Track API key usage patterns
  • • Secure Storage: Never commit keys to version control
  • • Team Access: Use separate keys for different team members

Enterprise Considerations

  • • Centralized Management: Use enterprise authentication
  • • Audit Trails: Comprehensive logging and monitoring
  • • Compliance: Meet regulatory requirements
  • • Data Governance: Implement data classification policies
