AWS fsx high security documentation change

Service: fsx · 2026-06-19 · Security-related high

File: fsx/latest/LustreGuide/configure-efa-clients.md

Summary

Added a new prerequisite step for configuring EFA-enabled security groups and renumbered subsequent steps

Security assessment

Added explicit requirement to configure security groups for EFA traffic, which prevents network misconfigurations that could expose Lustre clients. Failure to properly configure security groups could allow unauthorized access to sensitive file systems.
