AWS AmazonS3 medium security documentation change

Service: AmazonS3 · 2025-11-22 · Security-related medium

File: AmazonS3/latest/userguide/privatelink-interface-endpoints.md

Summary

Multiple changes including terminology updates ('AWS VPN' to 'Site-to-Site VPN'), added note about hybrid post-quantum TLS unsupported, URL formatting fixes, and VPN terminology consistency

Security assessment

The addition of 'Hybrid post-quantum Transport Layer Security (TLS)' to the unsupported features list directly documents a security-related limitation. This indicates awareness of cryptographic security considerations related to quantum computing threats.
