The system administrator must configure VPN access to meet organization-specific policies based on mission needs. Otherwise, a user could inadvertently or maliciously set up a VPN and connect to a network that poses unacceptable risk to DOD information systems. An adversary could exploit vulnerabilities created by the weaker configuration to compromise DOD sensitive information.

Review the list of unmanaged apps installed on the iPhone and iPad and determine if any third-party VPN clients are installed. If so, verify the VPN app is not configured with a DOD network (work/managed) VPN profile.
This validation procedure is performed on the iOS device only.
On the iPhone and iPad:
1. Open the Settings app.
2. Tap "General".
3. Tap the "VPN and Device Management" line and determine if any "Personal VPN" exists.
4. If not, the requirement has been met.
5. If there are personal VPNs, open each VPN app. Review the list of VPN profiles configured on the VPN client.
6. Verify no DOD network VPN profiles are configured on the VPN client.
If any third-party unmanaged VPN apps are installed (personal VPN), and they have a DOD network VPN profile configured on the client, this is a finding.
Note: This setting cannot be managed by the MDM administrator and is a User-Based Enforcement (UBE) requirement.

Password strength is a measure of the effectiveness of a password in resisting guessing and brute force attacks. The ability to crack a password is a function of how many attempts an adversary is permitted, how quickly an adversary can do each attempt, and the size of the password space. The longer the minimum length of the password is, the larger the password space. Having a too-short minimum password length significantly reduces password strength, increasing the chance of password compromise and resulting device and data compromise.

The more attempts an adversary has to guess a password, the more likely the adversary will enter the correct password and gain access to resources on the device. Setting a limit on the number of attempts mitigates this risk. Setting the limit at 10 or less gives authorized users the ability to make a few mistakes when entering the password but still provides adequate protection against dictionary or brute force attacks on the password.

Requiring all authorized applications to be in an application allow list prevents the execution of any applications (e.g., unauthorized, malicious) that are not part of the allow list. Failure to configure an application allow list properly could allow unauthorized and malicious applications to be downloaded, installed, and executed on the mobile device, causing a compromise of DOD data accessible by these applications. Applications with the listed characteristics have features that can cause the compromise of sensitive DOD data or have features with no known application in the DOD environment.
Application note: The application allow list, in addition to controlling the installation of applications on the MD, must control user access/execution of all core and preinstalled applications, or the MD must provide an alternate method of restricting user access/execution to core and preinstalled applications.

Many mobile devices display notifications on the lock screen so users can obtain relevant information in a timely manner without having to frequently unlock the phone to determine if there are new notifications. However, in many cases, these notifications can contain sensitive information. When they are available on the lock screen, an adversary can see them merely by being in close physical proximity to the device. Configuring the MOS to not send notifications to the lock screen mitigates this risk.

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.

Data on mobile devices is protected by numerous mechanisms, including user authentication, access control, and cryptography. When the data is backed up to an external system (either locally connected or cloud based), many if not all of these mechanisms are no longer present. This leaves the backed-up data vulnerable to attack. Disabling backup to external systems mitigates this risk.

App data sharing gives apps the ability to access the data of other apps for enhanced user functionality. However, sharing also poses a significant risk that unauthorized users or apps will obtain access to sensitive DOD information. To mitigate this risk, there are data sharing restrictions. If a user is allowed to make exceptions to the data sharing restriction policy, the user could enable unauthorized sharing of data, leaving it vulnerable to breach. Limiting the granting of exceptions to either the administrator or common application developer mitigates this risk.
Copy/paste of data between applications in different application processes or groups of application processes is considered an exception to the access control policy; therefore, the administrator must be able to enable/disable the feature. Other exceptions include allowing any data or application sharing between process groups.

Passwords provide a form of access control that prevents unauthorized individuals from accessing computing resources and sensitive data. Passwords may also be a source of entropy for generation of key encryption or data encryption keys. If a password is not required to access data, this data is accessible to any adversary who obtains physical possession of the device. Requiring that a password be successfully entered before the mobile device data is unencrypted mitigates this risk.
Note: MDF PP v2.0 requires a Password Authentication Factor and requires management of its length and complexity. It leaves open whether the existence of a password is subject to management. This requirement addresses the configuration to require a password, which is critical to the cybersecurity posture of the device.

When syncing an iPhone and iPad to a computer running iTunes, iTunes will prompt the user to back up the iPhone and iPad. If the performed backup is not encrypted, this could lead to the unauthorized disclosure of DOD sensitive information if non-DOD personnel are able to access that machine. Forcing the backup to be encrypted greatly mitigates the risk of compromising sensitive data. iTunes backup and USB connections to computers are not authorized, but this control provides defense-in-depth for cases in which a user violates policy either intentionally or inadvertently.

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.

The Apple iOS/iPadOS Mail app can be configured to support multiple email accounts concurrently. These email accounts are likely to involve content of varying degrees of sensitivity (e.g., both personal and enterprise messages). To prevent the unauthorized and undetected forwarding or moving of messages from one account to another, Mail ActiveSync Exchange accounts can be configured to block such behavior. While users may still send a message from the Exchange account to another account, these transactions must involve an Exchange server, enabling audit records of the transaction, filtering of mail content, and subsequent forensic analysis.

AirDrop is a way to send contact information or photos to other users with AirDrop enabled. This feature enables a possible attack vector for adversaries to exploit. Once the attacker has gained access to the information broadcast by this feature, the attacker may distribute this sensitive information very quickly and without DOD's control or awareness. By disabling this feature, the risk of mass data exfiltration will be mitigated.

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.

App data sharing gives apps the ability to access the data of other apps for enhanced user functionality. However, sharing also poses a significant risk that unauthorized users or apps will obtain access to sensitive DOD information. To mitigate this risk, there are data sharing restrictions. If a user is allowed to make exceptions to the data sharing restriction policy, the user could enable unauthorized sharing of data, leaving it vulnerable to breach. Limiting the granting of exceptions to either the administrator or common application developer mitigates this risk.
Copy/paste of data between applications in different application processes or groups of application processes is considered an exception to the access control policy; therefore, the administrator must be able to enable/disable the feature. Other exceptions include allowing any data or application sharing between process groups.

Review configuration settings to confirm "Allow documents from unmanaged apps in managed apps" is disabled.
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 iOS management tool, verify "Allow documents from unmanaged apps in managed apps" is unchecked.
On the iOS device:
1. Open the Settings app.
2. Tap "General".
3. Tap "VPN & Device Management".
4. Tap the Configuration Profile from the iOS management tool containing the restrictions policy.
5. Tap "Restrictions".
6. Verify "Opening documents from unmanaged to managed apps not allowed" is listed.
If "Allow documents from unmanaged apps in managed apps" is checked in the iOS management tool or the restrictions policy on the iPhone and iPad does not list "Opening documents from unmanaged to managed apps not allowed", this is a finding.
