AWS eks documentation change

Service: eks · 2026-05-22 · Documentation low

File: eks/latest/userguide/what-is-eks.md

Summary

Minor corrections: Updated 'FSX' to 'FSx' in storage options, fixed 'Cloudtrail' to 'CloudTrail' capitalization, and replaced 'cross-account elastic network interfaces' with linked 'requester-managed network interfaces' terminology.

Security assessment

Changes are editorial/cosmetic (capitalization fixes, terminology update with documentation link). No vulnerability, weakness, or security incident is mentioned. Network interface terminology update provides clearer technical accuracy but doesn't introduce security guidance.
