What are the security considerations when using AWS S3 and Cloudflare together?

Security is paramount. While S3 offers various security features like bucket policies and encryption, Cloudflare adds another layer of defense. Cloudflare's DDoS protection mitigates volumetric attacks targeting your S3 bucket. Properly configuring Cloudflare's security settings (e.g., WAF) and utilizing S3's access control mechanisms are essential to ensure data security and prevent unauthorized access. Consider using signed URLs in S3 for temporary access controlled by Cloudflare.
