The DoD warning banner can be displayed by either of the following methods (required text is found in the Vulnerability Discussion):

1. By placing the DoD warning banner text in the user agreement signed by each iPhone and iPad user (preferred method).
2. By creating a background picture with the relevant information and configuring that picture as the background for the lock screen via the Apple iOS/iPadOS management tool (only available for supervised devices).

Determine which method is used at the iOS device site and follow the appropriate validation procedure below.

Validation Procedure for Method #1:
Review the signed user agreements for several iOS device users and verify the agreement includes the required DoD warning banner text.

Validation Procedure for Method #2:
- In the Apple iOS/iPadOS management tool, verify a picture of the DoD warning banner text has been configured as the background for the lock screen.
- On the iOS device, verify a picture of the DoD warning banner text is shown as the background for the locked screen.

If, for Method #1, the required warning banner text is not on all signed user agreements reviewed, or for Method #2, the DoD warning banner text is not set as the locked screen background, this is a finding.
