AWS workspaces-thin-client high security documentation change

Service: workspaces-thin-client · 2025-10-13 · Security-related high

File: workspaces-thin-client/latest/ag/software-updates.md

Summary

Updated documentation about Software sets to clarify update types (monthly feature updates vs urgent security patches), added expiration policies (40 days for regular updates vs 3 days for security updates), and emphasized mandatory security updates overriding maintenance windows

Security assessment

Explicitly documents security-specific update handling: 1) Security patches trigger 3-day expiration for all prior versions (vs 40 days for regular updates) 2) Mandates immediate security updates to maintain device security 3) Reveals service forces automatic security updates regardless of user sessions when expired. These changes directly address security patch management processes and vulnerabilities from outdated software.

This type of update can interrupt active sessions because it won’t honor the maintenance window or allow end users to delay the update. To avoid this, we recommend updating Software sets at least once every 30 days.
