CIS Microsoft Windows 10 Enterprise Release 1909 Benchmark

2.3.7.9 (L1) Ensure 'Interactive logon: Smart card removal behavior' is set to 'Lock Workstation' or higher (Scored)

ProfileApplicability:

 Level 1 (L1) - Corporate/Enterprise Environment (general use)

Description:

This policy setting determines what happens when the smart card for a logged-on user is removed from the smart card reader. The recommended state for this setting is: Lock Workstation . Configuring this setting to Force Logoff or Disconnect if a Remote Desktop Services session also conforms to the benchmark.

Rationale:

Users sometimes forget to lock their workstations when they are away from them, allowing the possibility for malicious users to access their computers. If smart cards are used for authentication, the computer should automatically lock itself when the card is removed to ensure that only the user with the smart card is accessing resources using those credentials.

Audit:

Navigate to the UI Path articulated in the Remediation section and confirm it is set as prescribed, noting that values of Force Logoff or Disconnect if a Remote Desktop Services session arealso acceptable settings. This group policy setting is backed by the following registry location:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon:ScRemoveOption

Remediation:

To establish the recommended configuration via GP, set the following UI path to Lock Workstation (or, if applicable for your environment, Force Logoff or Disconnect if a Remote Desktop Services session ):
