Title

Administrator automatic logon is enabled. (Cat I impact)

Discussion

This is a category 1 finding because it will directly log on to the system with administrator privileges when the machine is rebooted. This would give full access to any unauthorized individual who reboots the computer. By default this setting is not enabled. If this setting exists, it should be disabled. If this capability exists, the password may also be present in the registry, and must be removed.

Check Content

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 “MSS: (AutoAdminLogon) Enable Automatic Logon (not recommended)” is not set to “Disabled”, then this is a finding. The policy referenced configures the following registry value: Registry Hive: HKEY_LOCAL_MACHINE Subkey: \Software\Microsoft\Windows NT\CurrentVersion\Winlogon\ Value Name: AutoAdminLogon Type: REG_SZ Value: 0 Note: The Gold Disk will also check for the existence of the HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\defaultpassword value. If it exists this will also make this a finding.

Fix Text

Configure the policy value for Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> “MSS: (AutoAdminLogon) Enable Automatic Logon (not recommended)” to “Disabled”.
