Service: dcv · 2026-09-27 · Documentation low

File: dcv/latest/adminguide/manage-smart-card.md

Summary

The Windows and Linux sections for enabling/disabling smart card caching were swapped in order; content is otherwise unchanged. No new security guidance added.

Security assessment

The diff only reorders existing Windows and Linux smart card caching instructions (e.g., moving the Windows Registry steps before the Linux dcv.conf steps). No new security feature, vulnerability fix, or hardening guidance is introduced.
