Ensure 'Allow remote users to interact with elevated windows in remote assistance sessions' is set to 'Disabled'

中级别 1自动化chrome

说明

Google Chrome can be set to run the remote assistance host in a process with uiAccess permissions. This allows remote users to interact with elevated windows on the local user's desktop. If this setting is disabled, the remote assistance host will run in the user's context. Furthermore, remote users cannot interact with elevated windows on the desktop. The recommended state for this setting is: Disabled (0) Rationale: Remote users shall not be able to escalate privileges. Audit reads the Group Policy registry value and prints 'compliant', 'unset' (policy not configured, reported as FAIL) or the non-compliant value. Registry value: HKLM\SOFTWARE\Policies\Google\Chrome:RemoteAccessHostAllowUiAccessForRemoteAssistance (REG_DWORD); compliant when it is 0. Remediation writes 0 locally; in a domain set it through the ADMX so Group Policy does not revert it.
