The System Administrator must have the capability to 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.

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.

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 that 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. 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:

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 DoD sensitive 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.

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.

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.

AirDrop is a way to send contact information or photos to other users with this same feature 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.
Note: If the site uses Apple's optional Device Enrollment Program (DEP), this control is available as a supervised MDM control.

Authorizing Official (AO) approval is required before an Apple Watch (DoD-owned or personally owned) can be paired with a DoD-owned iPhone to ensure the AO has evaluated the risk in having sensitive DoD data transferred to and stored on an Apple Watch in their operational environment.

The AutoFill functionality in browsers and applications allows the user to complete a form that contains sensitive information, such as PII, without previous knowledge of the information. By allowing the use of the AutoFill functionality, an adversary who learns a user's iPhone and iPad passcode, or who otherwise is able to unlock the device, may be able to further breach other systems by relying on the AutoFill feature to provide information unknown to the adversary. By disabling the AutoFill functionality, the risk of an adversary gaining further information about the device's user or compromising other systems is significantly mitigated.

When an iOS/iPadOS is not supervised, the DoD mobile service provider cannot control when new iOS/iPadOS updates are installed on site-managed devices. Most updates should be installed immediately to mitigate new security vulnerabilities, while some sites need to test each update prior to installation to ensure critical missions are not adversely impacted by the update.
Several password and data protection controls can be implemented only when an Apple device is supervised.

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.

Configuration profiles define security policies on Apple iOS devices. If a user is able to remove a configuration profile, the user can then change the configuration that had been enforced by that policy. Relaxing security policies may introduce vulnerabilities that the profiles had mitigated. Configuring a profile to never be removed mitigates this risk.

An adversary could exploit vulnerabilities created by the weaker configuration to compromise DoD sensitive information.
