AWS AWSCloudFormation documentation change

Service: AWSCloudFormation · 2026-06-13 · Documentation low

File: AWSCloudFormation/latest/TemplateReference/aws-properties-medialive-input-srtcallersourcerequest.md

Summary

Added detailed descriptions for SRT caller source configuration, including decryption requirements, latency settings, IP/port details, and StreamId importance for handshake

Security assessment

The change explicitly documents encryption requirements ('Complete these parameters only if the content is encrypted') and emphasizes StreamId's role in preventing SRT handshake failures. While this improves security documentation, there's no evidence of addressing a specific vulnerability.
