AWS vpc medium security documentation change

Service: vpc · 2025-10-22 · Security-related medium

File: vpc/latest/mirroring/create-traffic-mirroring-target.md

Summary

Restructured console steps, added security group configuration requirements for VXLAN traffic (UDP 4789), and clarified cross-account sharing.

Security assessment

Explicitly requiring a security group rule for VXLAN traffic addresses a potential misconfiguration risk. This change directly documents a security control to prevent unintended exposure of mirrored traffic, indicating a security-related improvement.
