MP.JL.CISOFFINT.L1.067 Excel: Set document behavior if file validation fails is set to Unchecked: Do not allow edit
Description
CIS Microsoft Intune for Office Benchmark, recommendation 2.2.4.7.2.3.5 (Level 1).
The test passes when an assigned settings catalog policy for Windows sets Microsoft Excel 2016 > Excel Options > Security > Trust Center > Protected View > Set document behavior if file validation fails to Enabled, with Allow edit set to Do not allow edit in the same policy, and no other assigned policy sets it to something else.
Remediation action
- In the Microsoft Intune admin center, go to Devices > Configuration and open (or create) a settings catalog policy for Windows 10 and later.
- Add Microsoft Excel 2016 > Excel Options > Security > Trust Center > Protected View > Set document behavior if file validation fails and set it to Enabled, then set Allow edit to Do not allow edit.
- Assign the policy to your Windows devices, and remove any other assigned policy that sets it to something else.
