AWS cost-management documentation change

Service: cost-management · 2025-11-22 · Documentation low

File: cost-management/latest/userguide/management-limits.md

Summary

Expanded quota details for anomaly detection monitors, added billing view limits, and clarified detection time/data requirements.

Security assessment

Changes focus on operational quotas and monitoring capabilities. While detection delays (24 hours) could indirectly impact security response, the documentation does not address a specific security vulnerability or introduce security controls.
