69.30 (L1) Ensure 'Special Administration Console Helper (sacsvr)' is set to 'Disabled' or 'Not Installed'

Information

This service allows administrators to remotely access a command prompt using Emergency Management Services.

The recommended state for this setting is: Disabled or Not Installed

Note: This service is not installed by default. It is supplied with Windows, but it is installed by enabling an optional Windows capability (

Windows Emergency Management Services and Serial Console

).

Allowing the use of a remotely accessible command prompt that provides the ability to perform remote management tasks on a computer is a security risk.

Solution

To establish the recommended configuration, set the following Custom Configuration Policy to 4 or confirm that the service is Not installed :

Name: <Enter name>
Description: <Enter Description>
OMA-URI:
./Device/Vendor/MSFT/Policy/Config/SystemServices/ConfigureSpecialAdministrationConsoleHelperServiceStartupMode
Data Type: Integer
Value: 4

Note: As of January 2024, despite its inclusion in Microsoft's official documentation, using an OMI-URI to configure a Windows Service Startup Mode via a custom profile will lead to an error in Intune. This error will be logged in the local event log as 'The system cannot find the file specified.' Currently, the most reliable method for remediation is through PowerShell.

The recommended configuration can also be established via PowerShell by running the following cmdlet:

Set-Service -Name sacsvr -StartupType Disabled

Impact:

Users will not have access to a remote command prompt using Emergency Management Services.
