    D --> E[Audit - Logging]

Authentication

• AWS Signature V4 - Request signing
• LDAP - Enterprise integration

Authorization

• Bucket Policies - IAM-style access control
• Conditions - IP, time, MFA

Encryption

• In Transit - TLS 1.2/1.3
• At Rest - AES-256-GCM

Audit

• Access logging
• Request tracing

Best Practices

1. Enable TLS in production
2. Use strong credentials
3. Enable encryption
4. Regular key rotation
5. Monitor access logs
