Ensure 'Encryption type for password protected Office Open XML files' is set to 'Enabled'

HochStufe 1Automatisiertintune-office

Beschreibung

This policy setting allows for specification of an encryption type for Office Open XML files. The chosen encryption type must have a corresponding cryptographic service provider (CSP) installed on the computer that encrypts the file. Note: This policy setting does not take effect unless the registry key HKEY_CURRENT_USER\Software\Microsoft\Office\16.0<office application name>\Security\Crypto\CompatMode is set to 0. By default the CompatMode registry key is set to 1. The recommended state for this setting is: Enabled: Microsoft Enhanced RSA and AES Cryptographic Provider,AES 256,256. Audit: reads the registry value(s) openxmlencryption that the Intune policy writes for every loaded user profile (HKEY_USERS) and prints compliant only when each satisfies the benchmark value.
