Title

The Smart Card removal option must be configured to Force Logoff or Lock Workstation.

Control

If the following registry value does not exist or is not configured as specified, this is a finding: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\ Value Name: SCRemoveOption Value Type: REG_SZ Value: 1 (Lock Workstation) or 2 (Force Logoff) This can be left not configured or set to "No action" on workstations with the following conditions. This must be documented with the ISSO. -The setting cannot be configured due to mission needs, or because it interferes with applications. -Policy must be in place that users manually lock workstations when leaving them unattended. -The screen saver is properly configured to lock as required.

Discussion

Unattended systems are susceptible to unauthorized use and must be locked. Configuring a system to lock when a smart card is removed will ensure the system is inaccessible when unattended.
