AWS eks documentation change

Service: eks · 2025-08-16 · Documentation low

File: eks/latest/userguide/hybrid-nodes-configure.md

Summary

Updated documentation to emphasize Cilium as the supported CNI, expanded application networking capabilities (BGP, Ingress, Load Balancing, Network Policies), and added new configuration guides for hybrid nodes

Security assessment

The change adds documentation for Kubernetes Network Policies configuration, which is a security control mechanism for pod communication. However, there is no evidence of addressing a specific security vulnerability. The removal of Calico support and focus on Cilium appears to be a compatibility/maintenance change rather than security-related.
