TMA-INTUNE-IOS-3.5.3
Ensure "Block untrusted TLS certificates" is set to "Yes"
Description
This recommendation blocks untrusted Transport Layer Security (TLS) certificates. The benchmark marks this a Manual check of an Intune iOS/iPadOS policy setting that cannot be read from the endpoint with a script, so TMAegis lists it as a manual review item with the audit steps (the policy must be inspected in the Intune admin center or on the managed device).
How it is checked
Audit method: Manual review
This recommendation cannot be checked automatically. A scan lists it with these instructions when you pass --include-manual.
iOS/iPadOS: Intune admin center: Select the General heading; Verify that Block untrusted TLS certificates is present and set to Yes. On the device: Tap Restrictions; Confirm Establishing untrusted TLS connections not allowed is displayed
How it is fixed
Fix method: Guidance or infrastructure patch
Intune admin center: Select the General heading; Set Block untrusted TLS certificates to Yes
