Ensure 'Restrict legacy JScript execution for Office' is set to 'Enabled'

中レベル 1自動intune-office

説明

This policy setting controls JScript execution per Security Zone within Internet Explorer and WebBrowser Control (WebOC) for Office applications. JScript is Microsoft's legacy dialect of the ECMAScript standard that is used in Microsoft's Internet Explorer 11 and older. If Enabled, Office applications will not execute legacy JScript for the Internet or Restricted Sites zones and users aren’t notified by the application that legacy JScript execution is restricted. Modern JScript9 will continue to function for all zones. ... Audit: reads the registry value(s) excel.exe, msaccess.exe, mspub.exe, onenote.exe, outlook.exe, powerpnt.exe, visio.exe, winproj.exe, winword.exe that the Intune policy writes under HKEY_LOCAL_MACHINE and prints compliant only when each satisfies the benchmark value.
