Before granting access to the system, the mobile operating system is required to display the DOD-approved system use notification message or banner that provides privacy and security notices consistent with applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance. Required banners help ensure DOD can audit and monitor the activities of mobile device users without legal restriction.

System use notification messages can be displayed when individuals first access or unlock the mobile device or in the User Agreement. The banner must be implemented as a "click-through" banner at device unlock (to the extent permitted by the operating system). A "click-through" banner prevents further activity on the information system unless and until the user executes a positive action to manifest agreement by clicking on a box indicating "OK".

The approved DOD text must be used exactly as required in the Knowledge Service referenced in DODI 8500.01. For devices accommodating banners of 1300 characters, the banner text is:

You are accessing a U.S. Government (USG) Information System (IS) that is provided for USG-authorized use only.

By using this IS (which includes any device attached to this IS), you consent to the following conditions:

-The USG routinely intercepts and monitors communications on this IS for purposes including, but not limited to, penetration testing, COMSEC monitoring, network operations and defense, personnel misconduct (PM), law enforcement (LE), and counterintelligence (CI) investigations.

-At any time, the USG may inspect and seize data stored on this IS.

-Communications using, or data stored on, this IS are not private, are subject to routine monitoring, interception, and search, and may be disclosed or used for any USG-authorized purpose.

-This IS includes security measures (e.g., authentication and access controls) to protect USG interests--not for your personal benefit or privacy.

-Notwithstanding the above, using this IS does not constitute consent to PM, LE or CI investigative searching or monitoring of the content of privileged communications, or work product, related to personal representation or services by attorneys, psychotherapists, or clergy, and their assistants. Such communications and work product are private and confidential. See User Agreement for details.

For devices with severe character limitations, the banner text is:

I've read & consent to terms in IS user agreem't.

The administrator must configure the banner text exactly as written without any changes.

The DOD warning banner can be displayed in the User Agreement (required text is found in the Vulnerability Discussion).

Review the signed user agreements for several iOS device users and verify the agreement includes the required DOD warning banner text.

If the required warning banner text is not on all signed user agreements reviewed, this is a finding.

Apple iOS/iPadOS 16 must implement the management setting: require the user to enter a password when connecting to an AirPlay-enabled device for the first time.

Rule Severity

Vuln Discussion

When a user is allowed to use AirPlay without a password, it may mistakenly associate the iPhone and iPad with an AirPlay-enabled device other than the one intended (i.e., by choosing the wrong one from the AirPlay list displayed). This creates the potential for someone in control of a mistakenly associated device to obtain DOD sensitive information without authorization. Requiring a password before such an association mitigates this risk. Passwords do not require any administration and are not required to comply with any complexity requirements.

Check Content

Review configuration settings to confirm "Require passcode on first AirPlay pairing" is enabled.

This check procedure is performed on both the Apple iOS/iPadOS management tool and the iPhone and iPad.

Note: If an organization has multiple configuration profiles, the check procedure must be performed on the relevant configuration profiles applicable to the scope of the review.

In the Apple iOS/iPadOS management tool, verify "Require passcode on first AirPlay pairing" is checked.

Alternatively, verify the text "<key>forceAirPlayOutgoingRequestsPairingPassword</key><false/>" appears in the configuration profile (.mobileconfig file).

On the iPhone and iPad:

1. Open the Settings app.

2. Tap "General".

3. Tap "VPN & Device Management".

4. Tap the Configuration Profile from the Apple iOS/iPadOS management tool containing the restrictions policy.

5. Tap "Restrictions".

6. Verify "AirPlay outgoing requests pairing password enforced" is listed.

If "Require passcode on first AirPlay pairing" is unchecked in the Apple iOS/iPadOS management tool, "<key>forceAirPlayOutgoingRequestsPairingPassword</key><true/>" appears in the configuration profile, or the restrictions policy on the iPhone and iPad does not list "AirPlay outgoing requests pairing password enforced", this is a finding.

Because Apple Watch is a personal device, it is key that any sensitive DOD data displayed on the Apple Watch cannot be viewed when the watch is not in the immediate possession of the user. This control ensures the Apple Watch screen locks when the user takes the watch off, thereby protecting sensitive DOD data from possible exposure.

Vuln Discussion

Managed apps have been approved for the handling of DOD sensitive information. Unmanaged apps are provided for productivity and morale purposes but are not approved to handle DOD sensitive information. Examples of unmanaged apps include those for news services, travel guides, maps, and social networking.

If a document were to be viewed in a managed app and the user had the ability to open this same document in an unmanaged app, this could lead to the compromise of sensitive DOD data. In some cases, the unmanaged apps are connected to cloud backup or social networks that would permit dissemination of DOD sensitive information to unauthorized individuals. Not allowing data to be opened within unmanaged apps mitigates the risk of compromising sensitive data.

Rule Severity

Rule Weight

Vuln Discussion

Many software systems automatically send diagnostic data to the manufacturer or a third party. This data enables the developers to understand real-world field behavior and improve the product based on that information. Unfortunately, it can also reveal information about what DOD users are doing with the systems and what causes them to fail. An adversary embedded within the software development team or elsewhere could use the information acquired to breach mobile operating system security. Disabling automatic transfer of such information mitigates this risk.
