Servers - Analyze the system using the Security Configuration and Analysis snap-in. Expand the Security Configuration and Analysis tree view. Navigate to Local Policies -> Security Options. If the value for “Interactive logon: Smart card removal behavior” is not set to “Lock Workstation”, or “Force Logoff”, then this is a finding. The policy referenced configures the following registry value: 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) Documentable Explanation: If configuring this on servers causes issues such as terminating users’ remote sessions and the site has a policy in place that any other sessions on the servers such as administrative console logons are manually locked or logged off when unattended or not in use, this would be acceptable. This will be documented with the IAO.
