AWS dcv documentation change

Service: dcv · 2025-11-13 · Documentation medium

File: dcv/latest/adminguide/manage-cert.md

Summary

Added macOS-specific instructions for TLS certificate management including file permissions and ownership requirements.

Security assessment

Certificate management documentation relates to security best practices, but the changes only add platform-specific implementation details rather than addressing a vulnerability. The chmod 600 instruction reinforces existing security practices.
