AWS AmazonCloudWatch documentation change

Service: AmazonCloudWatch · 2026-04-01 · Documentation medium

File: AmazonCloudWatch/latest/monitoring/DocumentHistory.md

Summary

Added two entries to document history: 1) Updated CloudWatchSyntheticsFullAccess policy with ListMetrics permission and restricted APIGateway permissions, 2) Updated AWSObservabilityAdminTelemetryEnablementServiceRolePolicy for new telemetry configurations.

Security assessment

The first update restricts APIGateway permissions from wildcard to specific resources, which follows the principle of least privilege and improves security posture. The second update documents policy changes for telemetry enablement. While these are security improvements, there's no evidence they address specific security incidents - they appear to be routine policy updates and enhancements.
