AWS lambda documentation change

Service: lambda · 2025-07-04 · Documentation medium

File: lambda/latest/dg/services-consume-kafka-events.md

Summary

Updated example configuration for Kafka event source mapping with simplified schema registry configuration and changed authentication type from CLIENT_CERTIFICATE_TLS_AUTH to BASIC_AUTH

Security assessment

While the change demonstrates different authentication methods (security documentation), the switch from mutual TLS to basic auth in examples could indicate security guidance changes but lacks explicit vulnerability context. The example now shows proper secret management practices.
