MP.JL.CISOFFINT.L1.038 Block Excel XLL Add-ins that come from an untrusted source is set to Enabled: Blocked

Severity: MediumGraph

Description

CIS Microsoft Intune for Office Benchmark, recommendation 2.2.4.7.2.5 (Level 1).

The test passes when an assigned settings catalog policy for Windows sets Microsoft Excel 2016 > Excel Options > Security > Trust Center > Block Excel XLL Add-ins that come from an untrusted source to Enabled, with Block Excel XLL Add-ins that come from an untrusted source set to Block in the same policy, and no other assigned policy sets it to something else.

Remediation action

  1. In the Microsoft Intune admin center, go to Devices > Configuration and open (or create) a settings catalog policy for Windows 10 and later.
  2. Add Microsoft Excel 2016 > Excel Options > Security > Trust Center > Block Excel XLL Add-ins that come from an untrusted source and set it to Enabled, then set Block Excel XLL Add-ins that come from an untrusted source to Block.
  3. Assign the policy to your Windows devices, and remove any other assigned policy that sets it to something else.
