AWS workspaces: WorkSpaces: add kpasswd port 464, fix TTCP typo

Service: workspaces · 2026-10-17 · Documentation medium

File: workspaces/latest/adminguide/workspaces-port-requirements.md · Type: network

Summary

Adds TCP/UDP 464 (kpasswd) to the listed directory ports that must be open, and corrects the typo 'TTCP 3268-3269 - Global Catalog' to 'TCP 3268-3269 - Global Catalog'.

Security assessment

The diff documents an additional firewall port requirement (TCP/UDP 464 for Kerberos password changes) and fixes a malformed protocol name so the Global Catalog rule is accurate; this is network configuration guidance/hardening with direct firewall-rule impact, though it is not tied to any specific vulnerability or CVE.

Evidence

+    * TCP/UDP 464 - kpasswd
